Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 to 3, the present embodiment provides an online differential speed adjusting device, which includes a transmission mechanism and an adjusting mechanism.
The transmission mechanism comprises a first bevel gear 4, a second bevel gear 5 and a third bevel gear 6, the axial directions of a gear shaft of the first bevel gear 4 and a gear shaft of the third bevel gear 6 are the same, and the gear shaft are arranged oppositely at intervals. The two second bevel gears 5 are oppositely arranged, the two second bevel gears 5 are oppositely arranged at intervals, and gear shafts are coaxially arranged. The second bevel gear 5 is arranged between the first bevel gear 4 and the third bevel gear 6, and the second bevel gear 5 is meshed with the first bevel gear 4 and the third bevel gear 6 respectively; a drive shaft 12 is connected between the two second bevel gears 5, and the second bevel gears 5 are rotatable relative to the drive shaft 12. The adjusting mechanism comprises a locking piece and an adjusting piece, the locking piece and the adjusting piece are respectively connected with the third bevel gear 6, the locking piece is used for enabling the third bevel gear 6 to be switched between a self-rotation state and a locking state, and the adjusting piece is used for applying an acting force for driving the third bevel gear 6 to rotate when the third bevel gear 6 is in the self-rotation state.
Wherein, the first bevel gear 4 is a power input end, and the driving shaft 12 is a power output end; or, the driving shaft 12 is a power input end, and the gear shaft of the first bevel gear 4 is a power output end. That is, when the online differential speed adjusting device of the present embodiment is used, the gear shaft of the first bevel gear 4 may be connected to a power input mechanism, for example, the power input transmission assembly 2 (sprocket, pulley, gear, etc.), in which case the driving shaft 12 is a power output end and is connected to a member to be driven, and the driving shaft 12 may be connected to the member to be driven through the power output transmission assembly 1, for example, sprocket, pulley, gear, etc. Alternatively, the drive shaft 12 may be connected to a power input mechanism, in which case the gear shaft of the first bevel gear 4 is the power output end and is connected to a member to be driven.
The second bevel gear 5 is rotatable with respect to the drive shaft 12, that is, the drive shaft 12 is not rotatable with the second bevel gear 5, but the drive shaft 12 revolves together with the second bevel gear 5 along the third bevel gear 6.
Taking the gear shaft of the first bevel gear 4 as a power input end and the driving shaft 12 as a power output end as an example, when the third bevel gear 6 is limited in the locked state by the locking member of the adjusting mechanism, the transmission ratio of the first bevel gear 4 and the second bevel gear 5 is determined, the first bevel gear 4 can drive the second bevel gear 5 to rotate and revolve relative to the third bevel gear 6, and the second bevel gear 5 can rotate relative to the driving shaft 12, so that the second bevel gear 5 can only drive the driving shaft 12 to revolve relative to the third bevel gear 6, that is, the driving shaft 12 rotates along the same axis as the axial extending direction of the gear shaft of the third bevel gear 6, and the output speed of the driving shaft 12 is controlled by the revolving speed of the second bevel gear 5 relative to the third bevel gear 6. When the speed difference needs to be adjusted, namely the output speed of a transmission system comprising the online differential adjusting device needs to be adjusted, the locking piece limits the third bevel gear 6 to a rotatable state, and at the moment, the acting force of rotation is applied to the third bevel gear 6 through the adjusting piece, the rotating speed of the third bevel gear 6 relative to the second bevel gear 5 is changed, namely the revolving speed of the second bevel gear 5 relative to the third bevel gear 6 is changed, and the purpose of adjusting the output speed of the driving shaft 12 is achieved.
The online differential adjusting device of the present embodiment can adjust the differential speed of the transmission systems of the two conveying mechanisms online by adjusting the output speed of the driving shaft 12, specifically, the online differential adjusting device of the present embodiment is installed in the transmission system of one of the conveying mechanisms, and then the speed difference adjustment of the two transmission systems is realized by adjusting the speed ratio of the transmission system in which the online differential adjusting device is installed. The machine does not need to be stopped, the required time is less, and the production efficiency is improved; meanwhile, the differential speed is adjusted through the third bevel gear 6, the operation is convenient, the differential speed adjusting range is large, and the adjusting precision is high.
Specifically, when the locking member limits the third bevel gear 6 to be in a rotatable state, the adjusting member applies an acting force to the third bevel gear 6, so that when the rotation directions of the third bevel gear 6 and the first bevel gear 4 are the same, the revolution speed of the second bevel gear 5 relative to the third bevel gear 6 is reduced, the rotation speed of the driving shaft 12 is reduced, and the transmission speed ratio is reduced; when the adjusting member applies an acting force to the third bevel gear 6 so that the rotation direction of the third bevel gear 6 is opposite to that of the first bevel gear 4, the revolution speed of the second bevel gear 5 relative to the third bevel gear 6 is increased, so that the rotation speed of the driving shaft 12 is increased, and the transmission speed ratio is increased.
Specifically, in the present embodiment, the modulus and the number of teeth of the first bevel gear 4 and the third bevel gear 6 are the same, so as to facilitate the setting of the second bevel gear 5. The module and the number of teeth of the two second bevel gears 5 are the same so that the drive shaft 12 rotates smoothly.
In a preferred mode, the module and the number of teeth of the first bevel gear 4, the second bevel gear 5 and the third bevel gear 6 are the same. That is, the first bevel gear 4, the second bevel gear 5 and the third bevel gear 6 are bevel gears of the same size or the same type. In this form, the center of the drive shaft 12 is collinear with the centers of the first bevel gear 4 and the third bevel gear 6, i.e., both on the axis of the first bevel gear 4 and the third bevel gear 6, and the axis of rotation of the drive shaft 12 can be conveniently determined, thereby conveniently connecting the drive shaft 12 to a power input mechanism or a member to be driven.
In order to facilitate the power output or power input of the driving shaft 12, a connecting shaft 13 is connected to the center of the driving shaft 12, the connecting shaft 13 is perpendicular to the driving shaft 12, and the connecting shaft 13 and the third bevel gear 6 are coaxially arranged. Specifically, a mounting hole is formed in the center of the driving shaft 12, the connecting shaft 13 is inserted into the mounting hole, and the connecting shaft 13 and the driving shaft 12 cannot move relatively in the circumferential direction of the connecting shaft 13, that is, the connecting shaft 13 needs to be relatively fixed in the circumferential direction with the hole wall of the mounting hole, so that the driving shaft 12 can drive the connecting shaft 13 to rotate; specifically, the connecting shaft 13 may be keyed to the driving shaft 12.
In order to facilitate the arrangement of the connecting shaft 13, through holes may be axially formed in the third bevel gear 6 and/or the first bevel gear 4, so that the connecting shaft 13 can pass through the through holes and then be connected with a power input mechanism or a member to be driven.
As a concrete form of the adjusting mechanism of the wire differential adjusting device of the present embodiment, the locking member includes a worm wheel 8, a worm 7 and a fastening member 9, the worm 7 is connected with the worm wheel 8, the worm wheel 8 is fixedly connected with the third bevel gear 6, and the fastening member 9 is used for fixing the worm 7.
Specifically, the online differential adjusting device generally further comprises a box body 3, a transmission mechanism, a worm wheel 8 and a worm 7 are arranged in the box body 3, a fastening piece 9 is fixed on the box body 3, the worm 7 and the box body 3 can be relatively fixed through the fastening piece 9, namely, the fastening piece 9 can limit rotation of the worm 7, the fastening piece 9 can be a clamping piece, a clamping portion is arranged on the worm 7, and the worm 7 is fixed after the fastening piece 9 is clamped with the clamping portion. When the fastening piece 9 is separated from the clamping part, the locking piece enables the third bevel gear 6 to be in a rotatable state, and when the fastening piece 9 is clamped with the clamping part, the locking piece enables the third bevel gear 6 to be in a locking state, namely a state that the third bevel gear cannot rotate.
The worm wheel 8 and the third bevel gear 6 can be fixedly connected through bolts and the like.
In the embodiment, in order to conveniently realize the locking or separating operation of the fastening member 9 and the worm 7, the fastening member 9 is fixed on the outer side wall of the box 3, one end of the worm 7, which is far away from the worm wheel 8, is connected with the auxiliary shaft 11, the auxiliary shaft 11 penetrates out of the box 3, and the fastening member 9 is used for being connected with the auxiliary shaft 11.
Corresponding to the form of the locking piece, the adjusting piece is a hand wheel 10, the hand wheel 10 is fixedly connected with the worm 7, and the specific hand wheel 10 is fixedly connected with one end of the auxiliary shaft 11 penetrating out of the box body 3.
It is to be noted that the hand wheel 10, the auxiliary shaft 11 and the worm 7 are arranged as coaxially as possible.
The power of the differential speed adjusting device of the present embodiment is input through the chain wheel of the power input transmission assembly 2, and assuming that the rotation speed is 2Nrpm (N in 2N is a positive integer), the chain wheel of the power input transmission assembly 2 and the first bevel gear 4 are connected into a whole through a bolt, so that the rotation speed of the first bevel gear 4 is 2 Nrpm. The first bevel gear 4 drives two second bevel gears 5 (the second bevel gears 5 are equivalent to planetary gears) to rotate, the second bevel gears 5 drive a third bevel gear 6 to rotate, and the final reduction ratio is calculated as follows:
assuming an angular velocity ω 1 of the first bevel gear 4, an angular velocity ω 2 of the second bevel gear 5, an angular velocity ω 3 of the third bevel gear 6; the speed reduction ratio i12 between the first bevel gear 4 and the second bevel gear 5, the speed reduction ratio i23 between the second bevel gear 5 and the third bevel gear 6, the speed reduction ratio i13 between the first bevel gear 4 and the third bevel gear 6 (the third bevel gear 6 is in a non-locking state):
i13＝(ω1-ω2)/(ω2ω1-ω3)＝-(Z1/Z3)＝-1
1-(ω1/ω2)＝-1，(ω1/ω2)＝i12＝2
the first bevel gear 4, the second bevel gear 5 and the third bevel gear 6 have the same number of bevel gears and module, so the rotation speed of the driving shaft 12 around the center line of the connecting shaft 13 is half of the sprocket input rotation speed 2Nrpm of the power input transmission assembly 2, and is Nrpm.
The connecting shaft 13 passes through the mounting hole of the driving shaft 12, and the two are connected by a key, so that the driving shaft 12 drives the connecting shaft 13, the rotating speed of the connecting shaft 13 is Nrpm, the connecting shaft 13 is connected with a chain wheel of the power output transmission assembly 1, and the rotating speed of the chain wheel of the power output transmission assembly 1 is Nrpm by the key connection. Namely, the input-output rotation speed ratio of the online differential speed adjusting device is 2: 1.
When the machine works normally, the fastening piece 9 is in a locking state, the auxiliary shaft 11 and the worm 7 do not rotate, the worm 7 locks the worm wheel 8, and therefore the third bevel gear 6 does not rotate. When the machine is abnormally operated and needs to be adjusted, the fastening piece 9 is loosened without stopping the machine, the hand wheel 10 is rotated, and the hand wheel 10 can rotate forwards and backwards as required, so that the worm 7 drives the worm wheel 8, the worm wheel 8 drives the third bevel gear 6 to adjust the rotating speed steplessly, and the phase adjustment of the upper and lower-stage related parts of the online differential adjusting device is achieved.
Naturally, when the connecting shaft 13 is used as an input and the first bevel gear 4 is used as an output, the corresponding input-output rotation speed ratio becomes 1: 2.
The online differential adjusting device of the embodiment is similar to a planetary differential mechanism, and has compact structure and stable transmission; the adjustment can be carried out in a positive phase and negative phase two-way manner, the online stepless adjustment can be realized, and the online adjustment of parts with larger self weight is convenient and labor-saving. Can be arranged at the power input or output position, and is conveniently connected with the upper and lower power.
The embodiment also provides a transmission system which comprises the online differential speed adjusting device.
Specifically, a gear shaft of the first bevel gear 4 is connected with the power input transmission assembly 2 of the power input mechanism, and specifically, the first bevel gear 4 and a chain wheel of the power input transmission assembly 2 are fixed into a whole through a bolt; the connecting shaft 13 is connected with the power output transmission assembly 1 so as to connect the power output transmission assembly 1 with a member to be driven, and specifically, the connecting shaft 13 may be in a form of being keyed with a shaft of the power output transmission assembly 1. Or the connecting shaft 13 connected with the driving shaft 12 can be fixedly connected with the power input mechanism, and the first bevel gear 4 is fixedly connected with a member to be driven.
The transmission system of the embodiment can combine a required speed ratio by adjusting the number of teeth of the upper and lower transmission connecting members of the power output transmission assembly 1 and the power input transmission assembly 2, and the like. That is, the speed ratio of the online differential speed adjusting device of the transmission system of the embodiment is constant when the third bevel gear 6 is in the locked state, and if different speed ratios are required in different transmission systems, the online differential speed adjusting device can be realized by adjusting the gear ratios of other speed reduction gear sets connected with the power output transmission assembly 1 or the power input transmission assembly 2 of the transmission system.
The dynamic system of this embodiment has the same beneficial effects as the online differential speed adjusting device provided in this embodiment, and the description of the effects of the online differential speed adjusting device can be specifically referred to, and will not be repeated herein.
