Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wheel rear cover technology, and more specifically, it relates to a heat dissipation structure for a rear cover assembly. Background Technology
[0002] The rear cover and the pump body together form a closed volume space (pump chamber). In traditional wheels, the rear cover shaft is solid and the bearing has a straight groove. When rotating, the liquid can only enter by the pressure of the pump body itself. The liquid cannot flow out to carry away the heat, which serves as simple lubrication. When the heat reaches a certain level, the shaft will break and the bearing will be damaged by friction. Utility Model Content
[0003] This disclosure relates to a heat dissipation structure for a rear cover assembly, which addresses the problem mentioned in the background art that the traditional wheel rear cover shaft is solid, the bearing has a straight groove, and when rotating, the liquid can only enter by the pressure of the pump body itself, and the liquid cannot flow out to carry away the heat, thus providing simple lubrication. When the heat reaches a certain level, problems such as shaft breakage and bearing friction damage will occur.
[0004] The heat dissipation structure of the back cover assembly of this utility model is achieved by the following specific technical means:
[0005] This utility model provides a heat dissipation structure for a rear cover assembly, comprising: a rear cover body, the rear cover body further comprising: a shaft, the shaft being circular in shape and fixedly installed inside the middle of the rear cover body; a bushing, the bushing being circular in shape and rotating outside the shaft; two planar slots, the planar slots being symmetrically opened at one end of the bushing; and a spiral groove, the spiral groove being opened inside the bushing.
[0006] As a preferred embodiment of this utility model, the rear cover body further includes a bearing, which is fixedly installed on the outside of the bushing.
[0007] As a preferred embodiment of this utility model, the back cover body further includes a perforation, which is formed in a cross shape in the middle of the axis, and the left and right ends of the perforation are designed to be through.
[0008] Compared with the prior art, the present invention has the following beneficial effects:
[0009] The coordinated rotation of the rear cover body and the precision-designed spiral grooves on the bushing drives the coolant or lubricating oil to be pumped out efficiently from the spiral grooves and flow smoothly into the perforation inside the shaft through the flat groove of the bushing, forming a continuous and stable internal circulation. This dynamic circulation system not only significantly improves the heat dissipation efficiency of key moving parts during high-speed operation and effectively prevents performance degradation or equipment damage caused by overheating, but also enhances the lubrication effect between friction pairs, greatly reducing wear and running resistance, thereby comprehensively improving the operational stability, reliability and service life of the equipment.

[0015] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.
[0016] Example: As attached Figure 1 To be continued Figure 3 As shown:
[0017] This utility model provides a heat dissipation structure for a rear cover assembly, comprising: a rear cover body 1, the rear cover body 1 further comprising: a shaft 101, the shaft 101 being circular in shape and fixedly installed inside the middle of the rear cover body 1; a bushing 102, the bushing 102 being circular in shape and rotating outside the shaft 101; two planar slots 103, the planar slots 103 being symmetrically opened at one end of the bushing 102; a spiral groove 104, the spiral groove 104 being opened inside the bushing 102; a bearing 105, the bearing 105 being fixedly installed outside the bushing 102; and a through hole 106, the through hole 106 being cross-shaped and opened in the middle of the shaft 101, with the left and right ends of the through hole 106 being designed to pass through.
[0018] The specific usage and function of this embodiment: As the rear cover body 1 and the spiral groove 104 of the bushing 102 rotate, the liquid will flow out from the spiral groove 104 of the bushing 102 and enter the through hole 106 of the shaft 101 in the flat groove 103 of the bushing 102 to form a circulation. This design greatly enhances the heat dissipation and lubrication when the spiral groove 104 rotates.
