AI Technical Summary

Technical Problem

The existing turntable flange structure design results in a large weight, making it difficult to meet the requirements for vehicle lightweighting.

Method used

By setting an outer raceway on the outer wall of the upper flange and an inner raceway on the inner wall of the lower flange, the balls are filled in the space enclosed by the outer raceway and the inner raceway. The outer arc surface design of the flange is optimized to reduce the outer diameter of the lower flange. At the same time, oil injection holes and sealing structures are set on the upper and lower flanges to facilitate lubrication and fixation of the balls.

Benefits of technology

The turntable was made lightweight, reducing the overall weight and meeting the requirements for vehicle lightweighting, thus improving transportation efficiency.

Abstract

This utility model relates to the field of turntable technology, specifically a lightweight turntable, comprising an upper flange, a lower flange, and ball bearings. The upper flange has an outer raceway on its outer wall, and the lower flange has an inner raceway on its inner wall. The ball bearings are filled in the space enclosed by the outer and inner raceways. The inner wall of the lower flange includes a first upper inner arc surface and a first lower inner arc surface, with the inner raceway located between the first upper and lower arc surfaces. By optimizing the structure of the upper and lower flanges and placing the ball bearings between the outer wall of the upper flange and the inner wall of the lower flange, the outer diameter of the lower flange can be smaller than that of the upper flange. This reduces the weight of the flanges while maintaining structural strength, achieving a lightweight turntable that allows vehicles to carry more cargo and improves transportation efficiency.
