AI Technical Summary

Technical Problem

In existing reducers, excessive lubricating media will affect the rotation efficiency when the gear is running, reducing the efficiency of the reducer.

Method used

A reducer is designed, with an oil barrier plate inside, which together defines an oil cavity with the shell body. An oil guide port is provided on the oil barrier plate to communicate with the oil cavity, thereby reducing the amount of lubricating media and avoiding affecting the operating efficiency of the gear set.

Benefits of technology

Through the design of the oil barrier plate, the lubricating medium can be stored in the oil chamber without affecting the operating efficiency of the gear set. When necessary, it enters the accommodation space through the oil guide port for lubrication, ensuring the normal lubrication of the gear set.

Abstract

The utility model discloses a speed reducer and a vehicle, the speed reducer comprises a shell body, the shell body is provided with a containing space, a gear set and an oil baffle plate are arranged in the containing space, the oil baffle plate is arranged on the shell body and located below the gear set, an oil liquid cavity is defined by the oil baffle plate and the shell body, and the oil liquid cavity is communicated with the containing space. At least one oil guide opening is formed in the oil baffle plate, and the containing space is communicated with the oil liquid cavity through the oil guide opening. According to the speed reducer, the oil baffle plate is arranged in the shell body, the oil liquid cavity is defined by the oil baffle plate and the shell body together, and therefore lubricating media can be stored in the oil liquid cavity and cannot affect the operation efficiency of a gear set, and the oil guide opening in the oil baffle plate can be communicated with the oil liquid cavity and the containing space. In this way, the gear set can be lubricated by the lubricating medium during operation.
