Embodiment Construction

[0012] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, the electric wheel hub motor gear is composed of a sun gear 1, a planetary gear 2 and an outer ring gear 3. The sun gear 1 is installed on the top of a mandrel, and when the mandrel rotates, the sun gear 1 will also rotate accordingly. With the sun gear 1 as the center, it meshes with three planetary gears 2, and the angles between the three planetary gears 2 are 120 degrees. There is an annular outer ring gear 3 outside the three planetary gears 2 , and the outer ring gear 3 meshes with the three planetary gears 2 at the same time.

[0014] On the sun gear 1, there is a sun gear boss 11, and the sun gear boss 11 is provided with teeth of different specifications on the sun gear 1. And the planet gear 2 meshed with the sun gear 1 also has a planet boss 21 , and the teeth provided on the planet boss 21 mesh ...

Abstract

The invention provides a firm and durable gear for a hub motor of an electric vehicle. The firm and durable gear comprises a sun gear, three large planetary gears and an outer gear ring. The three large planetary gears are meshed with the sun gear which is positioned in the center, and the outer annular gear ring is positioned outside the three large planetary gears and meshed with the same. The sun gear is provided with a sun gear boss, each large planetary gear is provided with a planetary boss, teeth of each planetary boss are meshed with teeth of the sun gear, and the outer gear ring is provided with an outer gear ring boss meshed with the planetary boss. Teeth of the sun gear, the large planetary gears and the outer gear ring are coated with abrasion-resistant layers with abrasion-resistant compositions. Therefore, abrasion resistance of the gears can be improved, and service lives of the gears can be prolonged. The firm and durable gear for the hub motor of the electric vehicle has the advantages that closeness of the gears is improved, abrasion of the gears is alleviated, and durability of the gears is improved.

Description

technical field [0001] The invention relates to an electric wheel hub motor part, in particular to a sturdy and durable electric wheel hub motor gear. Background technique [0002] As an essential part of the electric vehicle motor, the hub motor gear plays an important role. However, due to the long-term friction between the gears, each gear is damaged to varying degrees, thereby affecting the use of the electric vehicle and bringing potential safety hazards to the driver. In addition, ordinary gears may not mesh well with each other due to wear and tear, resulting in loosening of the gears. Contents of the invention [0003] The problem to be solved by the present invention is that the gears of the electric wheel hub motor will be worn due to long-term friction, and the worn gears are prone to loosening and other problems, which brings great potential safety hazards to the driver. [0004] In order to solve the above-mentioned technical problems, the technical solution...
