Embodiment Construction

[0028] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0029] refer to figure 1 , figure 2 and image 3 , a lightweight bearing provided in the embodiment of the present invention includes an outer ring 1 and an inner ring 2, the inner ring 2 and the outer ring 1 are provided with arc-shaped grooves 3 on the opposite side, and between the two arc-shaped grooves 3 are arranged There are a plurality of balls 4 evenly distributed. Specifically, the outer ring 1 and the inner ring 2 are made of steel, which is used to ensure the strength requirements of the high-speed rotation of the bearing. The surfaces of the arc groove 3 and the ball 4 are ...

Abstract

The invention relates to the technical field of bearings, in particular to a lightweight bearing, which solves the problem of relatively large friction between balls, cages and inner and outer rings in the prior art. A lightweight bearing, including an outer ring and an inner ring, arc grooves are formed on the opposite sides of the inner ring and the outer ring, and a plurality of evenly distributed balls are arranged between the two arc grooves, and the outer ring and the inner ring There are two symmetrically distributed cages between them. The two cages are located on both sides of the balls. There is a lubrication channel inside the outer ring. A lubrication mechanism is provided on the top of one of the balls. The mechanism communicates with the lubricating channel. The invention drives the lubricating oil to lubricate the ball and the arc groove through the relative rotation of the ball in the arc groove, effectively reducing the friction force between the ball and the arc groove, making the rotation effect of the bearing better, and meeting the high-speed rotation requirement of the bearing .

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a lightweight bearing. Background technique [0002] Lightweighting refers to the technical lightweighting of automobile production. The lightweight of the car is to reduce the curb weight of the car as much as possible on the premise of ensuring the strength and safety performance of the car, thereby improving the power of the car, reducing fuel consumption and reducing exhaust pollution. [0003] With the development of automotive technology, energy saving, light weight, maintenance-free, and low noise are the development directions of automotive applications. As a clutch release bearing, it is a power transmission component and is in a high-load and high-speed working state. High-frequency quenching is added to the steel material to meet the requirements of use. Modern light passenger vehicles require low energy consumption, low noise, and maintenance-free. Therefore, as a ...
