Description
Technical Field
[0001] This utility model relates to the field of air conditioning compressor technology, and in particular to a wear-resistant structure for the drive disc of an air conditioning compressor for new energy vehicles. Background Technology
[0002] During the operation of an air conditioner compressor, the drive component drives the drive disc to rotate. The drive disc works with the stationary disc to compress air. However, prolonged rotation will cause wear at the connection between the drive disc and the drive component, thus shortening the service life of the drive disc.
[0003] To address the shortcomings of existing technologies, it is necessary to design a wear-resistant drive disc structure for air conditioning compressors in new energy vehicles. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wear-resistant drive disc structure for a new energy vehicle air conditioning compressor.
[0005] A wear-resistant drive disc structure for a new energy vehicle air conditioning compressor includes a base plate, turbine teeth, a first bearing, several pin rings, and a drive component. The turbine teeth are fixed to one side of the base plate, and a bearing groove is formed at the center of the other side of the base plate. Several auxiliary rotating grooves are also formed on the same side of the bearing groove, surrounding the bearing groove. The first bearing is set in the bearing groove and is sleeved on the drive component to perform eccentric movement. The bottom of the auxiliary rotating groove is a single-layer stepped shape. The pin rings are set in the auxiliary rotating grooves and are flush with the opening and bottom step of the auxiliary rotating grooves, so that there is a gap between the pin rings and the bottom of the auxiliary rotating grooves.
[0006] Furthermore, the drive component includes a housing, a support plate, a rotor, an eccentric pin, and several auxiliary pins. The housing includes a large end and a small end, and a second bearing groove is formed inside the housing. A rotating annular groove is formed on the rotor shaft. The support plate is fixed to the large end of the housing, and the rotating shaft passes through from the small end to the large end, so that the small end of the housing is located in the rotating annular groove of the rotating shaft. A second bearing is sleeved on the rotating shaft and is located in the second bearing groove. The eccentric pin is fixed to the end of the rotating shaft and is located away from the axis of the rotating shaft. Several auxiliary pins are fixed to the support plate.
[0007] Furthermore, a counterweight is fitted onto the eccentric pin, and the first bearing is fitted onto the counterweight, so that the auxiliary pin is inserted into the auxiliary rotating groove and flush with the edge of the pin ring, and the large end is set to be polygonal.
[0008] Furthermore, a sealing groove is provided on the side of the turbine tooth away from the substrate, and a sealing strip is provided in the sealing groove.
[0009] Furthermore, the arc-shaped surface of the pin ring fits into the inner wall of the auxiliary rotating groove, and the plurality of auxiliary rotating grooves are equally distributed.
[0010] Furthermore, the substrate is provided with several oil grooves on the same side as the auxiliary rotating groove, and the support plate is also provided with several oil grooves.
[0011] Beneficial effects: By setting a pin ring, the wear of the auxiliary pin on the substrate is reduced to a certain extent, and the service life of the drive disk is increased. By setting the bottom of the auxiliary rotating groove to a single-layer stepped shape, the auxiliary pin is flush with the edge of the pin ring when it is submerged in the auxiliary rotating groove, which prevents the auxiliary pin from directly contacting the bottom of the auxiliary rotating groove and wearing the substrate. At the same time, the auxiliary pin helps the substrate to rotate stably when it makes eccentric movements. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] Please refer to Figures 1-4This embodiment proposes a wear-resistant drive disc structure for a new energy vehicle air conditioning compressor, including a base plate 1, turbine teeth 2, a first bearing 3, several pin rings 4, and a drive component 5. A sealing groove is formed on the side of the turbine teeth 2 away from the base plate 1, and a sealing strip is provided inside the sealing groove to ensure a tighter fit with the stationary disc and improve compression efficiency. The turbine teeth 2 are fixed to one side of the base plate 1. A bearing groove is formed at the center of the other side of the base plate 1. Several auxiliary rotation grooves 1a are also formed on the same side as the bearing groove, surrounding the bearing groove. The first bearing 3 is disposed in the bearing groove and is sleeved on the drive component 5 to perform eccentric movement, so that the inner... The oil-gas mixture can be rapidly compressed from the periphery to the center of the turbine tooth 2 to compress the oil and gas. The bottom of the auxiliary rotating groove 1a is a single-layer stepped shape. The pin ring 4 is set in the auxiliary rotating groove 1a and is flush with the opening and bottom step of the auxiliary rotating groove 1a, so that there is a gap between the pin ring 4 and the bottom of the auxiliary rotating groove 1a to prevent wear on the substrate 1 and affect its service life. The arc-shaped surface of the pin ring 4 fits against the inner wall of the auxiliary rotating groove 1a. Several auxiliary rotating grooves 1a are equally distributed to ensure the stability of the substrate 1 when it makes eccentric movements. Several oil grooves are opened on the substrate 1, which are opened on the same side as the auxiliary rotating groove 1a.
[0015] The drive component 5 includes a housing 51, a support plate 52, a rotor 53, an eccentric pin 54, and several auxiliary pins 55. The housing 51 has a large end and a small end, with the large end being polygonal. A second bearing groove is provided inside the housing 51. A rotating annular groove is provided on the rotating shaft of the rotor 53. The support plate 52 is fixed to the large end of the housing 51. The housing 51 and the support plate 52 are installed in a housing for mounting the drive component 5. The rotating shaft extends from the small end to the large end, so that the small end of the housing 51 is located in the rotating annular groove of the rotating shaft, allowing the rotating shaft to rotate within the housing 51. A second bearing groove is sleeved on the rotating shaft. Two bearings are provided, with the second bearing located in the second bearing groove. An eccentric pin 54 is fixed to the end of the rotating shaft and located away from the axis of the rotating shaft. Several auxiliary pins 55 are fixed on the support plate 52. A counterweight 56 is sleeved on the eccentric pin 54, and the first bearing 3 is sleeved on the counterweight 56, so that the auxiliary pins 55 are inserted into the auxiliary rotating groove 1a and flush with the edge of the pin ring 4, preventing direct contact with the substrate 1 and wear of the substrate 1. The counterweight 56, the auxiliary rotating groove 1a, and the auxiliary pins 55 ensure the stability of the substrate 1 during eccentric movement without abnormal noise. Several oil grooves are also provided on the support plate 52.
[0016] The eccentric pin 54 drives the substrate 1 to make eccentric movements. The auxiliary pin 55 assists the substrate 1 to rotate stably when it makes eccentric movements. In order to prevent the auxiliary pin 55 from wearing the substrate 1 when it rotates, the pin ring 4 is set to reduce the wear of the auxiliary pin 55 on the substrate 1 to a certain extent and increase the service life of the drive disk. By setting the bottom of the auxiliary rotation groove 1a to a single-layer stepped shape, the auxiliary pin 55 is prevented from directly contacting the bottom of the auxiliary rotation groove 1a and wearing the substrate 1.
[0017] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
