New description: [New technical field] This creation is about the assembly and disassembly structure, especially the bearing assembly and disassembly used in the bicycle wheel axle for the main purpose, which does not need to remove the rim seat and Spokes and those who can perform the unwinding of bearings. [Prior Art] The wheel of the bicycle is mainly used to make the rim rotate smoothly after fine positioning. Therefore, in the wheel valley group, a plurality of bearing rods are usually mounted on the shaft center to be the gorge, and the silk syllabus reads it. The green wheel _ in the state of rotation 2 can produce forward. In the bicycle wire group, the role of the bearing element is quite important. The design of the position and the size of the inner and outer frame diameters requires a high degree of precision. In particular, the inner and outer frames of the bearing must be in a fixed state. The internal balls or rollers can be effectively actuated. Therefore, the butterfly members and their assembly parts are also required to have high precision requirements. However, the bearing length _ lang, plus the wheel home if there is no force to easily produce offset or wear, such as bearing wear and tear, resulting in poor accuracy, or offset, there will be a smooth rotation, affecting riding Comfort, at this time, the replacement and maintenance of the bearing must be carried out, so the appropriate disassembly and assembly tools, or the use of the fixture and the fixture are required to facilitate the maintenance work. Bicycle wheel 1^m, money_When the wheel is unloaded by the car red, it must be tilted to the financial field with the big wealth of material. The M408632 is removed from the bearing, and the bearing must be taken out with the appropriate machine. The tools for such removal are mostly gas-oil pressure drivers, in order to provide larger power to take out the tightly-positioned bearings; when assembling the bearings, the bearing assembly accuracy requirements are very high, so it is necessary to match the appropriate tools accurately, The bearings are pressed into the flower valley seat without offset. Most of these machines are pneumatic oil pressure drivers to provide greater power to press the bearings in and tightly position. In addition to the above-mentioned applications of large-scale machines, there are also simple mechanical disassembly tools for bearing disassembly assembly, bearing disassembly on the domain bike or • assembly tools will be different due to the disassembled bicycle parts and components. And there are different structural design and disassembly methods. According to the conventional structure of the bicycle bearing disassembly or assembly, such as the "bearing removal tool" disclosed in the new patent No. 099204372, the main I is provided with a card for supporting the object to be disassembled. And in the middle of the above-mentioned card fastener, there is a movable piece which is traversed and can be vertically displaced, and the bottom part of the movable piece is the bottom piece of the movable piece, and the _ end is provided for use. Wherein the width of the y-side of the abutting member is smaller than the bearing aperture, so that the abutting member is pivoted and passes through the bearing hole, and the ends of the abutting member are larger than the bearing hole k for acquitting the bearing and the bearing and the movable member Common displacement. There is also a kind of self-loading bearing loading and unloading tool, such as the "bearing loading and unloading tool" disclosed in the domestic new (4) No. 4 new patent, which has a tool body, the tool = the body has a solid piece and is fixed on the tool body and fixed The pieces are respectively formed with a connecting drive gear. The connecting end is formed at one end of the tool body, the connecting end plate tool body is formed with a clear part, and the connecting end is provided with a clip, and the working piece 4 M408632 has The other end of the body is provided with a corresponding phase portion and a light member, and corresponding adjusting portions are respectively formed between the fixing plate adjusting members, and are respectively formed on the inner and outer sides of the outer wall of each fixing portion. Department and card department. [New content] In the above-mentioned structure, 'all of them are suitable for the bearing disassembly tool of the bicycle five-way pipe part'. The main function of the former structure is that the bearing in the item to be disassembled can be pulled out by the hooking force. The hooking force is applied to reduce the damage of the bearing body, so that the disassembled bearing parts can continue to be assembled and used; the latter structure has the effect of facilitating loading and unloading. However, the former structure is only a tool for disassembling the bearing and cannot be assembled, and the structure is used when the bearing of the wheel set is disassembled, because the inner frame of the bearing is close to the one piece, the movable piece cannot be inserted into the inside. The frame is rotated behind, so it is not suitable for the rotation of the wheel group; the latter is pulled out by the Lai, and the bearing is pushed out to the opposite end. This structure is used when the bearing of the wheel group is disassembled. Because the bearing groove of the hub group has a stepped bottom edge for blocking the outer diameter frame of the bearing, it cannot be pushed out in the reverse direction, and therefore is not suitable for the bearing of the hub group. On the other hand, for large bearing disassembling machines, it is necessary to remove the wheel from the frame to carry out the replacement of the bearing operation. 'There are some special wheel hub structures and even all the spokes need to be removed to carry out the bearing replacement work. It also consumes energy in space. It is only suitable for professional assembly factories or bicycle shops. It must be a professional familiar with this machine. It is not suitable for the general consumers who want to replace the bearings themselves. 5 M408632 (Technical means for solving the problem) In view of the fact that the bearing of the bicycle hub disclosed in the present invention is provided, the inside of the fitting is provided with an abutting member to be detached from the two ends of the abutting member, and has a sleeve The outer diameter of the seat is = the disassembly seat, the disassembly and the abutment are respectively threaded through the disassembly bolt, and the basin is provided with the reverse thread--the reverse screw--installation group. a seat, and a central locking portion thereof is disposed on the outer side end of the inner diameter sleeve and at least one shaft is provided with a screw-locking seat, and a corresponding positioning seat is disposed on the other side of the corresponding rim group, The bolts are set up by the slaves and the 魄_, _ wire group, the other end snails = the _ seat 妓 妓 each of the components and the bearing is positioned in the bearing groove; the simple and suitable for the trough group The structural design eliminates the need for special wheel training and can replace the bearing. At the same time, compared with the large machine, the manufacturing cost is low and it does not occupy space. Therefore, the replacement structure can be convenient and practical. (Compared with the effect of the first miscellaneous technique) The purpose of the ΓΓ ΓΓ 即 即 在 在 在 在 在 在 自行车 自行车 自行车 自行车 自行车 自行车 自行车 自行车 自行车 自行车 自行车 自行车 自行车 自行车 自行车 自行车 自行车 自行车 自行车 自行车 自行车 自行车 自行车 自行车 自行车 自行车 自行车 自行车 自行车 自行车 自行车 自行车 自行车The reduced material is transferred into the 仃 bearing replacement to achieve the effect of simple and quick replacement operation. The second of this creation - the purpose is to provide a bicycle-wheel bearing group unloading 6 device 'is a simple mechanical structure, can be replaced without special professional training 'suitable threats - like _ people's bribes and secrets . The purpose of this creation is to provide a bicycle wheel that is unloaded and placed in comparison with the bearing set. The structure is simple and has the dual functions of "disassembling" and "assembling" the wheel bearing'. Compared with the Dalaitai Weizhi County, Lin Take up space.

Until the bearing groove (13) is completely disengaged, the disassembly is completed. The disassembly group (20) of the present invention uses the end surface of the abutting member (14) to completely abut the inner diameter frame of the bearing (33) for use. The reverse screwing structure of the positive and reverse threads's use of the screwing structure can generate a larger screwing force, so that the dismounting bolts (22) # and the abutting members (丨4) move in opposite directions, and further Push the bearing (33) completely out. For the bearing assembly operation of this creation, please refer to the eighth to eleventh drawings. At this time, the bearing group (10) is not equipped with bearings. First, the set bolts (37) are serially connected to the positioning seats. (36), an inner diameter sleeve (31), and a bearing (34), and the central protrusion (311) of the inner diameter sleeve (31) is inserted into the inner diameter hole of the bearing (34) 'The aforementioned assembly member is threaded from one end of the hub group (1〇) through the set screw (37) through the abutting member (14); and the other end of the hub group is passed through the set screw (37), and Each of the bearing (33), the inner diameter sleeve (32), and the screw lock seat (35) are serially connected in series, and the central protrusion (321) of the inner diameter sleeve (32) is threaded to abut Inside the inner diameter hole of the bearing (33); continuously set each of the set bolts (37) and the screw lock seat (35) until the members are pressed against each other' at this time each bearing (33) (34) is subjected to After the pressing, the clamping device is placed in each of the bearing slots (13), that is, the assembly operation is completed. The installation group (3〇) of the present invention uses the set bolts (37) to screw the screw lock seat (35), the gap between the two is shortened, and the screw structure can generate a large transmission 'power' And each of the members that are worn therein is pressed against each other, and the inner k-seat (31) (32) of the step 9 is completely abutted against the inner diameter frame of each of the bearings (33) (34) and On the side, when the bearing (10) (10) is tight, the yaw is not generated, which reduces the unevenness of the plane when the press-in is performed. The wheel bearing assembly unloading device of the present invention is designed in a "mechanical" structure, and the replacement of the bearing is carried out with a simple member. The principle of generating a large transmission force by using the screwing structure can be used for each bearing. (34) Remove from the tight positioning state, or press the bearing (33) (34) into the bearing groove (13) in a tightly fitting state, and the general personnel can perform bearing replacement in a general place. It is known that the main engine driven by gas oil pressure takes up space and consumes a large amount of energy, and requires a professional to perform replacement work. This creation is a simple tool design. When the car body is positioned on the ground, the bearing can be replaced directly after the two ends of the axle are removed. It is not necessary to remove the wheel on the frame. The spokes are removed one by one, so that the replacement operation can be achieved simply and quickly, and the problem of the large-scale design of the professional machine tool clips and fixtures is required, and the wheels must be removed. This creation also has the dual functions of “disassembling” and “assembling” wheel bearings. Compared with the conventional bicycle disassembly tools, the single “demolition” or single “assembly” design is more Practical and convenient. Referring to Figures 12 to 17, it is another embodiment of the present invention, which mainly combines the disassembly group (20) and the installation group (3〇) into a device, wherein A bolt (37) is integrally formed at the other end of the dismounting bolt (22), and has a rod portion (38) of a preset length; the inner diameter sleeve (31) is integrally formed on the dismounting bolt ( 22) Preset the part. In the embodiment, when assembling the bearing operation, please refer to the fourteenth to fifteenth drawings. First, the disassembly bolts (22) and the set bolts (37) are connected in series to the bearing (33), and the inner diameter is made. The central protrusion (311) of the sleeve (31) is inserted into the inner diameter hole of the bearing (33); the assembly member is passed through the end of the hub group (1〇) through the abutting member ( 14) inside; the screw (37) of the set which is pierced by the other end of the hub group (丨〇), and the bearings (34), the inner diameter sleeve (32), and the screw lock seat are sequentially connected in series. (35), and the central protrusion (321) of the inner diameter sleeve (32) is inserted into the inner diameter hole of the bearing (34); and the set bolts (37) and the screw are continuously screwed The lock seat (35) is until the members are pressed against each other, and at this time, each of the bearings (33) (34) is tightly positioned and positioned in each of the bearing grooves (13), that is, the assembly is completed. operation.
