[0002] A universal joint is a mechanical component that realizes variable-angle power transmission. It is used in positions where the direction of the transmission axis needs to be changed. It is the "joint" component of the universal joint device of the automobile drive system. The combination of the universal joint and the drive shaft is called a universal joint transmission device, and the bell housing is an important component of the universal joint.

[0003] During use, the steel ball and the bell-shaped housing of the existing universal joint will rub against each other. Long-term friction will cause the bell-shaped housing to be easily damaged, which will directly affect power transmission. Although lubricating oil is added to the contact point between the steel ball and the bell-shaped housing in advance, a dust cover is usually installed on the outside to prevent dust, which makes it inconvenient to add lubricating oil again. Therefore, it is necessary to develop a wear-resistant bell-shaped housing. Utility Model Content

[0029] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] See also Figure 1-Figure 6 , shows a schematic diagram of the structure of a wear-resistant bell-shaped housing embodiment of the utility model, please refer to Figure 1-Figure 6 , a wear-resistant bell-shaped housing is introduced in detail.

[0031] A wear-resistant bell-shaped housing, comprising a housing 100, the housing 100 is bell-shaped and has an annular fixing frame 110 at the right end, the fixing frame 110 has receiving grooves 120 formed around the center of the ring at equal intervals, and the inner side of the receiving groove 120 is provided with an oil guide hole 130 connected to the outer wall of the fixing frame 110;

[0032] Annular annular sealing plates 200 are symmetrically arranged on the left and right sides of the outer wall of the fixing frame 110, and the outer wall of the fixing frame 110 is symmetrically arranged with partitions 210 protruding around the center of the ring at equal intervals. The left and right sides of each partition 210 are fixedly connected to the side walls of two annular sealing plates 200 respectively, and the positions of the plurality of partitions 210 correspond to the positions of the plurality of oil guide holes 130, and the partitions 210 block the outer ends of the oil guide holes 130, and the side walls of the partitions 210 are opened with openings 220, and the inner side walls of the openings 220 are opened with oil inlet holes 230 connected to the outer ends of the oil guide holes 130;

[0033] An annular swivel 300 is provided on the outer edges of the two annular sealing plates 200 for rotating together, and a connecting plate 310 is protruded around the inner wall of the swivel 300 at equal intervals around its own ring center, and a sealing plate 320 is protruded from the other end of each connecting plate 310. The connecting plate 310 and the sealing plate 320 are integrally arranged and are "L" shaped as a whole. The position and number of the sealing plates 320 correspond to the opening 220, and the rotating swivel 300 drives all the sealing plates 320 to be inserted / pulled out of the opening 220 one by one.

[0034] Furthermore, a connecting shaft 140 is disposed at the left end of the housing 100 , and the connecting shaft 140 includes a connecting spline 150 for connecting other components.

[0035] Furthermore, the outer wall of the partition 210 is also opened with a through opening 240, and the inner side of the through opening 240 is staggered with the oil inlet hole 230. The space between two adjacent partitions 210 and two annular sealing plates 200, as well as the inner side of the swivel 300 and the outer side of the shell 100 can be regarded as a chamber for storing lubricating oil. Through the set through opening 240, all the chambers are interconnected.

[0036] Furthermore, a sealing gasket is provided at the gap between the outer edge of the annular sealing plate 200 and the swivel 300, and a sealing layer 250 is provided at the gap between the inner wall of the opening 220 and the outer wall of the sealing plate 320. The sealing gasket and the sealing layer 250 can be made of rubber material. Among them, although the sealing gasket will appropriately increase the friction force when the swivel 300 rotates, it makes the chamber as a whole more sealed and reduces oil leakage. In addition, the swivel 300 itself rotates manually and will not rotate frequently, and the rotation angle is also small.

[0037] Furthermore, oil filling holes 330 are opened on the inner and outer sides of the rotating ring 300, and the oil filling holes 330 are staggered with the partition 210. A sealing plug 340 is provided on the oil filling hole 330. After opening the sealing plug 340, the lubricating oil is injected into the chamber through the oil filling hole 330, and through the through port 240, so that the entire chamber is filled with lubricating oil.

[0038] Furthermore, the outer side of the rotating ring 300 is provided with anti-skid patterns 350 , and the anti-skid patterns 350 are staggered with the oil filling holes 330 . The anti-skid patterns 350 increase the friction between the fingers and the outer side of the rotating ring 300 when the rotating ring 300 is rotated, making it easier to apply force.

[0039] Furthermore, an annular convex ring 360 is protruded from the outer wall of the shell 100 near the left side of the swivel 300, and an annular fixed ring 370 is provided on the left side of the swivel 300. The inner side of the fixed ring 370 is concavely provided with an annular groove 380. The outer wall of the convex ring 360 is inserted into the groove of the groove 380 and is rotatably connected. The convex ring 360 is inserted into the groove 380, which can limit the fixing ring 370 and the swivel 300, so that the swivel 300 is rotatably set on the outside of the shell 100.

[0040] Furthermore, a plurality of rotating shafts 390 are arranged at equal intervals in the groove of the groove 380 with the center of the fixed ring 370 as the center. Each of the rotating shafts 390 is rotatably arranged in the groove of the groove 380, and the surface of the rotating shaft 390 is in contact with the outer edge of the convex ring 360. When the rotating ring 300 rotates, it drives the fixed ring 370 to rotate, and the convex ring 360 slides along the surfaces of the plurality of rotating shafts 390, thereby reducing the friction between the contact surfaces of the convex ring 360 and the groove 380 when rotating.

[0041] During specific use, after opening the sealing plug 340, the lubricating oil is injected into the chamber through the oil filling hole 330, and through the through port 240, the entire chamber is filled with lubricating oil. When it is necessary to lubricate the receiving groove 120 to reduce the friction between the receiving groove 120 and components such as steel balls, the user rotates the rotating ring 300 counterclockwise to drive all the blocking plates 320 to be pulled out of the inner side of the opening 220 one by one. At this time, the oil inlet hole 230 is opened and connected to the oil guide hole 130, and the lubricating oil flows into the groove of the receiving groove 120 through the oil guide hole 130, thereby reducing the friction with the steel balls and slowing down the wear of the inner side of the receiving groove 120 by the steel balls; after a short period of oil filling, the rotating ring 300 is rotated counterclockwise again to drive all the blocking plates 320 to be inserted into the inner side of the opening 220 one by one, thereby sealing the oil inlet hole 230, and the lubricating oil inside the chamber is ready for next use.

[0042] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
