Description

A new type of cross-axis universal joint bearing

Technical Field

The utility model relates to the technical field of universal joint bearings, and more specifically, to a novel cross-axis universal joint bearing.

Background technique

Universal joint bearing refers to a mechanical structure that uses ball-type connections to achieve power transmission on different shafts. It is a very important component of automotive bearings. The combination of universal joints and drive shafts is called a universal joint transmission device. The classification of universal joint bearings includes: constant velocity universal thrust ball bearing joints, constant velocity universal joints, ball cage universal joints, tripod universal bearing joints, double-jointed universal joints, etc.

Detailed ways

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Referring to Figures 1 and 2, a new type of cross-axis universal joint bearing includes a cross-axis 1 and a plurality of bearings 2 arranged on the cross-axis 1. The cross-axis 1 is filled with lubricating fluid. The bearing bushings in the plurality of bearings 2 include a metal base and a liner cloth. The material of the metal base is precipitation-hardened stainless steel. The use of precipitation-hardened stainless steel 05Cr15Ni5Cu4Nb can improve the bearing capacity of the bearing. The use of the liner cloth can enhance the self-lubricating performance of the bearing, reduce the friction coefficient of the bearing, and further reduce the wear of the bearing. The main materials of the liner cloth are polyester, polytetrafluoroethylene fiber and prepreg. The surface of the liner cloth has a twill texture. The raw materials of the twill cloth are polyester and polytetrafluoroethylene fiber. Since a three-up and one-down interlacing method or a two-up and one-down interlacing method is used when weaving the cloth, the twill texture is obtained. Twill texture can make more polytetrafluoroethylene fibers appear on the front of the twill cloth, so that the twill cloth has good self-lubricating properties and a lower friction coefficient. The prepreg is a mixed glue, and its main components include phenolic resin, carbon black, graphite powder, molybdenum disulfide, curing agent, and reinforcing agent. The mass ratio of each component is: 92.5:0.5:1.5:1.5:2:2. After the twill cloth and prepreg are made, the prepreg can be evenly applied to the surface of the prepreg, and then the prepreg is placed on the vulcanizer for pressurization (1.5MPa), heating and heat preservation, and heat preservation at 75-80℃ for 1-2 hours, 120-130℃ for 2-3 hours, and naturally cooled after heating and heat preservation. The cooled prepreg is then machined to make the size and thickness of the prepreg meet the design requirements. At this time, the prepreg becomes a lining cloth with self-lubricating and wear-resistant properties. After the liner cloth and the metal base are bonded and fixed by an adhesive, a bearing bushing with self-lubricating performance is manufactured, and the bearing bushing is matched with a cross shaft to complete the manufacture of the cross shaft type universal joint bearing.

Two conical rings 32 are fixedly connected to the side wall of the dust stop ring 31. The two conical rings 32 are located on one side of the bearing 2 respectively. The cross section of the conical ring 32 is triangular, so that one end of the conical ring 32 can overlap the bearing 2, which can further prevent impurities and foreign matter from entering. At the connection between the bearing 2 and the cross shaft 1, a protective ring 33 is fixedly connected to the side wall of the dust stop ring 31, and a plurality of balls 34 in contact with the bearing 2 are inlaid on the side wall of the protective ring 33. The plurality of sealing assemblies 3 are respectively located on one side of the plurality of bearings 2. It is particularly noteworthy that the balls 34 can block relatively large impurities and foreign matter, and at the same time, the balls 34 can enable the normal operation of the bearing 2, and the protective ring 33 is cylindrical, which further prevents foreign matter from the outside from contacting the bearing 2, thereby extending the service life of the bearing 2.

5, 6 and 7, a conducting component 8 is connected to the rotating component 7, and the conducting component 8 is located inside the cross shaft 1. The conducting component 8 includes two turbine blades 81 coaxially fixedly connected to the side wall of the rotating shaft 71, a collar 82 coaxially fixedly connected to the side wall of the rotating shaft 71, and two symmetrical scraper rods 83 fixedly connected to the side wall of the collar 82. One end of the two scraper rods 83 is respectively located below the through hole 65, and a notch is provided at the top of the scraper rod 83. When the grease is discharged, the scraper rod 83 can scrape the grease to one side, thereby avoiding that part of the grease is accumulated on one side of the through hole 65. The lower end surface of the second sealing cover 62 is provided with two second bearings 84, and the two second bearings 84 are rotatably connected to friction cylinders 85 respectively in contact with the two scraper rods 83. It is particularly noted that the friction cylinder 85 and the scraper rod 83 are in contact with each other, and the scraper rod 83 can generate heat, which can further soften the grease, so that it can be quickly melted into the lubricating oil.

In actual operation, when the electromagnetic column 52 is working, with the assistance of the magnetic column 72, when the cross shaft 1 moves back, the lubricating oil in the cross shaft 1 can be continuously moved, so that the turbine blades 81 can rotate accordingly, and with the assistance of multiple forces, the rotating shaft 71 can be rotated, and with the assistance of the reciprocating thread 74 and the vertical rod 64, the circular plate 63 can be moved accordingly.

At the same time, when the rotating shaft 71 rotates, the collar 82 can be rotated, so that the scraper rod 83 can be rotated. At the same time, when the scraper rod 83 rotates, the scraper rod 83 and the friction cylinder 85 can be brought into contact. It is particularly noteworthy that the scraper rod 83 is made of heat-conducting material, so that the grease accumulated on the scraper rod 83 can be quickly softened, and the grease can be further melted into the lubricating oil.
