Description

适合汽车整车输送和瓦楞纸物流输送的网链输送***Mesh chain conveyor system suitable for vehicle transportation and corrugated logistics transportation 技术领域technical field
本发明属于输送设备技术领域，特别是网链输送***的结构设计。The invention belongs to the technical field of conveying equipment, in particular to the structural design of a net chain conveying system.
背景技术Background technique
网链输送***由两个传动链轮以及环形配合在传动链轮上的传送带构成，现有的汽车整车输送，瓦楞纸等重物的物流输送大多采用塑料模块化的链板作为传送带，链板由多个链节组成，相邻的链节之间以销轴形成转动相连，这种传送功能的实现是靠链板上设置的啮合槽和传动链轮的轮齿相啮合而实现的。由于啮合槽设置在链节背面，并在啮合槽的前后两侧的外端分别设置弧面，理论上要求轮齿自啮合槽的外端进入到达啮合槽的底部，使轮齿的齿面与啮合槽完全啮合，从而实现传动。但是，在重负载驱动模式下，链节会因为负载使链板节距的拉大，使后一个啮合面沿前面的转销旋转至链轮的齿面时受阻而无法顺利进入啮合槽理论位置，链轮啮合链节中啮合槽两侧弧面位置下移，改变了对弧面的受力方向，使链板受到了更大的向外推力，过大负载啮合过程造成跳齿。并且，受力状况的齿形受力面在受力过程中产生一定的位移滑动，滑动产生的摩擦使啮合弧面磨损，改变了原始的形状。链板在使用过程中跳齿会影响输送的平稳性，并会对链板造成磨损，随着长期跳齿现象的发生会对链轮的轮齿形成磨损，甚至链板会被拉断，致使链板的使用寿命缩短。这种现象会随着输送物 料重量加大，负载增加，链板的跳齿情况会更加严重，影响网链输送***的输送能力。The mesh chain conveying system is composed of two drive sprockets and a conveyor belt that is annularly fitted on the drive sprockets. The existing vehicle conveyance and the logistics conveyance of heavy objects such as corrugated paper mostly use plastic modular chain plates as conveyor belts. It is composed of a plurality of chain links, and the adjacent chain links are connected in rotation by pin shafts. The realization of this transmission function is realized by the meshing grooves set on the chain plate and the gear teeth of the transmission sprocket. Since the meshing groove is arranged on the back of the chain link, and the outer ends of the front and rear sides of the meshing slot are respectively provided with arc surfaces, it is theoretically required that the gear teeth enter from the outer end of the meshing slot to the bottom of the meshing slot, so that the tooth surface of the gear tooth and the The engaging grooves are fully engaged to achieve transmission. However, in the heavy-load driving mode, the chain link will increase the pitch of the chain plate due to the load, so that the rear meshing surface will be blocked from rotating along the front pin to the tooth surface of the sprocket and cannot smoothly enter the theoretical position of the meshing groove. , the position of the arc surface on both sides of the meshing groove in the meshing link of the sprocket moves down, which changes the direction of the force on the arc surface, so that the chain plate is subjected to a greater outward thrust, and the excessive load meshing process causes the teeth to jump. In addition, the tooth-shaped force-bearing surface in the force-bearing state produces a certain displacement and sliding during the force-bearing process, and the friction generated by the sliding wears the meshing arc surface and changes the original shape. The tooth skipping of the chain plate during the use process will affect the smoothness of the conveying and cause wear to the chain plate. With the long-term tooth skipping phenomenon, the teeth of the sprocket will be worn, and even the chain plate will be broken, resulting in The service life of the chain plate is shortened. This phenomenon will increase with the increase of the weight of the conveyed material and the increase of the load, and the tooth skipping of the chain plate will become more serious, which will affect the conveying capacity of the mesh chain conveying system.
还有一种网链输送***的链板也是由多个链节组成，每个链节的前后两端分别设置成排的凸耳，前后相邻的链节之间通过销轴相互连接，链节背面设置有可容置传动链轮轮齿的啮合槽，在啮合槽前侧链节的凸耳后表面设有弧形面。在链轮的转动下链板发生运动，是由于传动链轮的轮齿进入链节内的啮合槽，并且该轮齿的齿面抵触在链节凸耳表面的弧形面而实现的。由于这种啮合是线接触，导致轮齿在啮合过程中与凸耳的接触位置不断发生变化，当轮齿的顶角与凸耳接触时，凸耳会受到链轮径向且向外的分力，使输送网链的输送面会产生跳动，直接影响了输送网链的输送效果和使用寿命。There is also a chain plate of a mesh chain conveying system that is also composed of multiple chain links. The front and rear ends of each chain link are respectively provided with rows of lugs, and the adjacent chain links are connected to each other through pins. The back is provided with a meshing groove that can accommodate the gear teeth of the transmission sprocket, and the rear surface of the lug of the chain link on the front side of the meshing groove is provided with an arc surface. The movement of the chain plate under the rotation of the sprocket is realized because the gear teeth of the transmission sprocket enter the meshing grooves in the chain link, and the tooth surface of the gear tooth interferes with the arc surface of the lug surface of the chain link. Since this meshing is a line contact, the contact position between the gear teeth and the lug constantly changes during the meshing process. When the apex angle of the gear tooth is in contact with the lug, the lug will be divided radially and outwardly by the sprocket. The force will cause the conveyor surface of the conveyor chain to jump, which directly affects the conveying effect and service life of the conveyor chain.
发明内容SUMMARY OF THE INVENTION
针对以上现有技术的缺陷，本发明提出一种可提高输送平稳性和使用寿命的适合汽车整车输送和瓦楞纸物流输送的网链输送***。In view of the above-mentioned defects of the prior art, the present invention proposes a network chain conveying system suitable for vehicle vehicle conveying and corrugated paper logistics conveying, which can improve conveying stability and service life.
本发明包括传动链轮以及配合在传动链轮上的环形输送网链，所述环形输送网链包括沿输送网链长度方向顺次插接的多个链节，每个链节沿输送网链的长度方向分别设置前排凸耳和后排凸耳，相邻链节的凸耳之间沿输送网链的宽度方向交错布置、并通过销轴转动连接，每个链节的背面设置啮合槽，其特征在于：在与设置啮合槽的链节相邻的前一链节的后排凸耳的表面设有相互连续的弧形面和平面，所述连续的弧形面和平面朝向该啮合槽，所述弧形面较平面接近链节的正 面，传动链轮的轮齿的齿面为斜面，链节通过所述平面与轮齿的所述斜面相啮合。The invention includes a transmission sprocket and an annular conveying network chain matched with the transmission sprocket, the annular conveying network chain includes a plurality of chain links inserted in sequence along the length direction of the conveying network chain, and each chain link is along the conveying network chain. The front row lugs and the rear row lugs are respectively arranged in the length direction of the chain link, and the lugs of the adjacent chain links are arranged staggered along the width direction of the conveyor network chain and connected by the rotation of the pin shaft, and the back of each chain link is provided with a meshing groove , which is characterized in that: the surface of the rear row of the lugs of the previous chain link adjacent to the chain link with the engaging groove is provided with mutually continuous arc-shaped surfaces and planes, and the continuous arc-shaped surfaces and planes face the engagement. The arc surface is relatively flat and close to the front surface of the chain link, the tooth surface of the gear tooth of the transmission sprocket is an inclined surface, and the chain link meshes with the inclined surface of the gear tooth through the flat surface.
本发明在链节的凸耳上设置有用于与传动链轮的轮齿相啮合的平面，该平面与轮齿的齿面在啮合传动过程中保持平行贴合状态，这种面与面的相抵触使传动过程中两者之间的啮合始终是面接触，从根本上改变了现有技术的线接触，因此本发明的这种设计可有效避免了跳齿，不会出现输送网链在传送过程中传送面的起伏变化，从而有效提高了输送效果，也延长了整个***的使用寿命。In the present invention, the lug of the chain link is provided with a flat surface for meshing with the gear teeth of the transmission sprocket, and the flat surface and the tooth surface of the gear teeth maintain a parallel fit state during the meshing transmission process. The friction makes the meshing between the two always be in surface contact during the transmission process, which fundamentally changes the line contact in the prior art. Therefore, the design of the present invention can effectively avoid tooth skipping, and there will be no transmission network chain in the transmission. The fluctuation of the conveying surface during the process effectively improves the conveying effect and prolongs the service life of the entire system.
当本发明用于重负载输送时，既使链板会因为重负载使链板节距拉大，使后一个啮合面沿前面的转轴旋转至轮齿的齿面时受阻，从而进入了偏外的节圆位置，轮齿啮合链节的平面时，位置上移的链节啮合轮齿齿面的位置改变，但平面与齿面相互受力方向也不会发生改变。当链板节距变大，链板节圆变大，只要轮齿的齿面能够啮合链节的该平面的任何状态下，链轮驱动力都能传递给链节啮合面。因为轮齿的压力角度很小，轮齿对链节的向外推力小，轮齿与链节以平面接触，因此在***的使用过程中产生的位移滑动产生的磨损不会改变链节的平面和轮齿的齿面原始形状。When the present invention is used for heavy-load conveying, even if the chain plate will increase the pitch of the chain plate due to the heavy load, the latter meshing surface will be blocked when it rotates along the front rotating shaft to the tooth surface of the gear teeth, thereby entering the outer When the gear tooth meshes with the plane of the chain link, the position of the gear tooth surface of the chain link that moves up will change, but the mutual force direction between the plane and the tooth surface will not change. When the pitch of the chain plate becomes larger and the pitch circle of the chain plate becomes larger, as long as the tooth surface of the gear teeth can engage the plane of the chain link in any state, the driving force of the sprocket can be transmitted to the meshing surface of the chain link. Because the pressure angle of the gear teeth is small, the outward thrust of the gear teeth on the chain link is small, and the gear teeth and the chain link are in plane contact, so the wear caused by the displacement and sliding during the use of the system will not change the plane of the chain link. and the original shape of the tooth surface of the gear teeth.
本发明避免了中间圆弧面驱动形式链节与轮齿贴合旋转产生的翻转脱齿的现象，在一定范围内的链板节距大小使链板相应在链轮的对应径向节圆位置贴合传动，同时利用改变啮合位置的径向节圆大小来适应链板受力及磨损引起的节距变化，(更适合齿数较少的设计)。链板的较大径向啮合范围的啮合面避免了输送链板的爬齿、跳齿现 象，避免了因为跳齿引起的拉断输送网链现象的发生。The invention avoids the phenomenon of overturning and disengagement caused by the coupling and rotation of the chain link and the gear teeth in the form of intermediate arc surface driving, and the chain plate pitch size within a certain range makes the chain plate corresponding to the corresponding radial pitch circle position of the chain wheel. Fit the transmission, and at the same time use the radial pitch circle size that changes the meshing position to adapt to the pitch change caused by the force and wear of the chain plate (more suitable for designs with fewer teeth). The meshing surface of the large radial meshing range of the chain plate avoids the phenomenon of tooth climbing and tooth skipping of the conveyor chain plate, and avoids the occurrence of the phenomenon of breaking the conveyor network chain caused by the skipping tooth.
以上节圆指工作状态链节销孔中心在齿轮的圆周上的直径。The above pitch circle refers to the diameter of the center of the pin hole of the chain link on the circumference of the gear in the working state.
本发明适用于所有输送行业，尤其适合汽车整车输送、瓦楞纸物流输送这样的大负载输送行业。The present invention is suitable for all conveying industries, and is especially suitable for large-load conveying industries such as vehicle conveying and corrugated paper logistics conveying.
进一步地，上述平面可以为与弧形面相切的切面。采用切面为啮合面的优点是链节脱离齿轮时没有距离拉大的阻力。Further, the above-mentioned plane may be a tangent plane to the arc-shaped surface. The advantage of using the cut surface as the meshing surface is that there is no resistance to increasing the distance when the chain link is disengaged from the gear.
所述切面在相连续的弧形面上的切点与后排凸耳轴心的连线和切面所属的链节的前、后排凸耳的轴心连线之间的夹角为β，β＝360°/链轮齿数+n，其中，链轮齿数为大等于4的整数，n＝0～3°。当n为0°时，切面同后一节链节销孔垂直，轮齿对链节的向外推力为零，这种情况下更适合应用于大负载状况中。The angle between the tangent point of the tangent plane on the continuous arc surface and the line connecting the axis of the rear lug and the line connecting the axis centers of the front and rear lugs of the chain link to which the tangent plane belongs is β, β=360°/number of sprocket teeth+n, wherein the number of sprocket teeth is an integer greater than or equal to 4, and n=0˜3°. When n is 0°, the tangent plane is perpendicular to the pin hole of the chain link of the following link, and the outward thrust of the gear teeth on the chain link is zero. In this case, it is more suitable to be used in heavy load conditions.
上述平面也可以为与弧形面相交的相交面。采用相交面为啮合面的优点：链节脱离齿轮时有距离拉大的阻力，没有相切的容易脱开，但在上述范围内可以使用。The above-mentioned plane may also be an intersecting plane intersecting with an arc-shaped plane. The advantage of using the intersecting surface as the meshing surface: when the chain link is disengaged from the gear, there is a resistance to increasing the distance, and the one without tangent is easy to disengage, but it can be used within the above range.
所述相交面与链节上的一切面相互平行；所述切面在与相交面相连续的弧形面上的切点与后排凸耳轴心的连线和切面所属的链节的前、后排凸耳的轴心连线之间的夹角为β，β＝360°/链轮齿数+n，其中，链轮齿数为大等于4的整数，n＝0～3°，所述相交面在与该相交面相连接的弧形面上的上交点与后排凸耳轴心的连线和前、后排凸耳的轴心连线之间的夹角为α，α≥β/2。The intersection surface and the tangent plane on the chain link are parallel to each other; the connection line between the tangent point of the tangent plane on the arc surface continuous with the intersection plane and the axis of the rear row of lugs and the front and rear of the chain link to which the tangent plane belongs. The included angle between the lines connecting the axes of the row lugs is β, β=360°/number of sprocket teeth+n, wherein the number of sprocket teeth is an integer greater than or equal to 4, n=0～3°, the intersecting surface The angle between the upper intersection point on the arc surface connected to the intersecting surface and the line connecting the axis of the rear lugs and the line connecting the axis centers of the front and rear lugs is α, α≥β/2.
更进一步地，所述弧形面可以为与后排凸耳轴心同心的圆弧面。Further, the arc surface may be a circular arc surface concentric with the axis of the rear row of lugs.
在网链输送***的设计中，不但需要保证轮齿能平稳自如地与链 节啮合，也要保证轮齿能平稳自如地自链节中分离出来。当链轮转动至进入回程段时，链板的咬合斜面需要从链轮上脱开，链节驱动其平面旋离链轮的齿面，链节的弧形面与轮齿的齿面接触，脱离这个状况如果是链节上为圆弧面时，圆弧面驱动同轮齿的啮合面接触磨损后形成平面或其他的形状都会造成接触面到孔的距离小于凸耳其他位置到孔的距离，会产生链节旋离阻力，产生脱离困难勾链现象，因此，本发明所述链节上的弧形面也可以为与后排凸耳轴心非同心的弧面，弧面同斜面相切的位置离孔中心距离最大，并渐渐减小，使切线交点到销轴孔中心点的距离大于其他咬合面前部的圆弧距离，使链节与轮齿容易相互脱开。In the design of the mesh chain conveying system, it is not only necessary to ensure that the teeth can mesh with the chain links smoothly and freely, but also to ensure that the teeth can be separated from the chain links smoothly and freely. When the sprocket rotates to enter the return section, the occlusal surface of the chain plate needs to be disengaged from the sprocket, the chain link drives its plane to rotate away from the tooth surface of the sprocket, and the arc surface of the chain link is in contact with the tooth surface of the gear teeth. If it is out of this situation, if the chain link has a circular arc surface, the arc surface driving and the meshing surface of the gear teeth will form a plane or other shape after contact and wear, which will cause the distance from the contact surface to the hole to be smaller than the distance from other positions of the lug to the hole. , it will cause the chain link to rotate away resistance, resulting in the phenomenon that the chain link is difficult to escape. Therefore, the arc surface on the chain link of the present invention can also be an arc surface that is not concentric with the axis of the rear lug, and the arc surface is the same as the inclined surface. The distance between the cut position and the center of the hole is the largest, and gradually decreases, so that the distance from the intersection of the tangent line to the center of the pin shaft hole is greater than the arc distance at the front of the other occlusal surfaces, so that the chain link and the gear teeth are easily separated from each other.
另外，本发明还可在朝向啮合槽的前一链节和后一链节的凸耳的表面分别设有相互连续的弧形面和平面，以利于双向传输。In addition, the present invention can also be provided with mutually continuous arc surfaces and flat surfaces on the surfaces of the lugs of the former chain link and the latter chain link facing the engaging groove, so as to facilitate bidirectional transmission.

具体实施方式detailed description
如图1、2、3所示，本发明由至少一个传动链轮1以及配合在传动链轮1上的一根环形输送网链2组成，各传动链轮1均匀地分布有多个轮齿11，输送网链2则由多个沿输送网链2的长度方向顺次插接的链节21组成，每个链节21沿输送网链的长度方向分别设置前排凸耳211和后排凸耳212，相邻链节21的前、后排凸耳之间沿输送网链2的宽度方向交错布置、并通过销轴22转动连接。As shown in Figures 1, 2, and 3, the present invention consists of at least one transmission sprocket 1 and an annular conveying network chain 2 matched on the transmission sprocket 1, and each transmission sprocket 1 is evenly distributed with a plurality of gear teeth 11. The conveyor network chain 2 is composed of a plurality of chain links 21 that are inserted in sequence along the length direction of the conveyor network chain 2. Each chain link 21 is respectively provided with front row lugs 211 and rear row along the length direction of the conveyor network chain. The lugs 212 are arranged staggered along the width direction of the conveyor mesh chain 2 between the front and rear lugs of the adjacent chain links 21 , and are rotatably connected through the pin shaft 22 .
每个链节21的背面设置啮合槽213，在与设置有啮合槽213的链节21相邻的前一链节21的后排凸耳212的表面设有相互连续的弧形面214和平面215，弧形面214和平面215都朝向啮合槽213，并且弧形面214较平面215接近链节21的正面，弧形面214与链节21的正面形成光滑的过渡连接。An engaging groove 213 is provided on the back of each chain link 21, and a continuous arc surface 214 and a flat surface are provided on the surface of the rear row of lugs 212 of the preceding chain link 21 adjacent to the chain link 21 provided with the engaging groove 213. 215 , the arcuate surface 214 and the flat surface 215 both face the engaging groove 213 , and the arcuate surface 214 is closer to the front surface of the chain link 21 than the flat surface 215 , and the arcuate surface 214 forms a smooth transition connection with the front surface of the chain link 21 .
此处的弧形面214可以为与后排凸耳212的轴心同心的圆弧面，弧形面214也可以为与后排凸耳轴心非同心的弧面，弧面同斜面相切的位置离孔中心距离最大，并渐渐减小。The arc surface 214 here can be an arc surface concentric with the axis of the rear lug 212, and the arc surface 214 can also be an arc surface that is not concentric with the axis of the rear lug, and the arc surface is tangent to the inclined plane. The distance from the center of the hole is the largest and gradually decreases.
传动链轮1的轮齿11的齿面为斜面，链节21通过其平面215与轮齿11的斜面相啮合。The tooth surface of the gear teeth 11 of the transmission sprocket 1 is an inclined surface, and the chain link 21 meshes with the inclined surface of the gear teeth 11 through its flat surface 215 .
如图3所示，后排凸耳212的平面215为与弧形面214相切的切面。As shown in FIG. 3 , the plane 215 of the rear row of lugs 212 is a tangent plane to the arcuate surface 214 .
并且，切面在相连续的弧形面214上的切点与后排凸耳212轴心的连线L1和切面所属的链节21的前、后排凸耳的轴心连线L2之间的夹角为β。In addition, the tangent point of the tangent plane on the continuous arc-shaped surface 214 and the line L1 connecting the axial centers of the rear lugs 212 and the axis connecting line L2 of the front and rear lugs of the chain link 21 to which the tangent plane belongs. The included angle is β.
β＝360°/链轮齿数+n，其中，链轮齿数为大等于4的整数，n 为链节脱开补偿角度，n＝0～3°。β=360°/number of sprocket teeth+n, where the number of sprocket teeth is an integer greater than or equal to 4, n is the compensation angle of chain link disengagement, and n=0～3°.
采用切面为啮合面的优点：如图3中D1是在销轴径向上切点至后排凸耳212的最小距离，链节脱离齿轮时没有距离拉大的阻力。The advantage of using the tangent surface as the meshing surface: as shown in Figure 3, D1 is the minimum distance from the tangent point in the radial direction of the pin to the rear lug 212, and there is no resistance to increase the distance when the chain link is separated from the gear.
又如图4所示，后排凸耳212的平面为与弧形面214相交的相交面。As also shown in FIG. 4 , the plane of the rear row of the lugs 212 is an intersecting surface intersecting with the arc-shaped surface 214 .
并且，相交面与链节21上图3中所示的切面相互平行。并且相交面在与该相交面相连接的弧形面214上的上交点与后排凸耳轴心的连线L3和前、后排凸耳的轴心连线L1之间的夹角为α，α≥β/2。Also, the intersecting plane and the tangent plane shown in FIG. 3 on the chain link 21 are parallel to each other. And the angle between the upper intersection point of the intersecting surface on the arc-shaped surface 214 connected to the intersecting surface and the connecting line L3 of the axis of the rear lug and the axis connecting L1 of the front and rear lugs is α, α≥β/2.
采用相交面为啮合面的优点：如图4中D2是在销轴径向上相交点至后排凸耳212的距离，由于D2＜D1链节脱离齿轮时有距离拉大的阻力，没有相切的容易脱开，但在上述范围内可以使用。The advantage of using the intersecting surface as the meshing surface: as shown in Figure 4, D2 is the distance from the intersection point in the radial direction of the pin shaft to the rear lug 212. Since the D2<D1 chain link has the resistance to increase the distance when it is separated from the gear, there is no tangent. easy to disengage, but can be used within the above range.
再如图5所示，后排凸耳212中与弧形面214相交或相切的面为近似于平面的弧形面。As shown in FIG. 5 again, the surface of the rear row of lugs 212 that intersects or is tangent to the arcuate surface 214 is an arcuate surface that is approximately a plane.
如图6所示的输送网链中，在朝向啮合槽213的前一链节和后一链节的凸耳的表面分别设有相互连续的弧形面和平面215。这种结构可以用于双向传输的网链输送***中。In the conveyor mesh chain shown in FIG. 6 , the surfaces of the lugs of the previous link and the rear link facing the engaging groove 213 are respectively provided with mutually continuous arc surfaces and flat surfaces 215 . This structure can be used in the network chain conveying system of bidirectional transmission.
