A ball screw multi-arc end plug reverser

Abstract

The invention discloses a novel ball screw multi-arc end plug inverter. According to the end plug inverter disclosed by the invention, the fluency of balls passing through the inverter is improved by optimizing a ball return curve of the inverter, so that the vibration and the noises of a ball screw pair are reduced, and the comprehensive performance of the ball screw pair is improved. The novel ball screw multi-arc end plug inverter is characterized by comprising an inverter inlet raceway (101), a plurality of arc raceways (102, 103 and 104), and an inverter inlet raceway (105), wherein the inlet ends of the arc raceways (102, 103 and 104) are tangent to the inverter inlet raceway (101); the inlet of the inverter inlet raceway (105) is tangent to the outlets of the arc raceways (102, 103 and 104).

Description

technical field [0001] The invention relates to the field of high performance rolling features. In particular, it relates to a novel multi-arc end plug ball reverser. Background technique [0002] High-performance ball screw pair is the key rolling function part of high-end CNC machine tools. High-performance ball screw sets need to have a smoother ball return method than ordinary screws. In order to meet the development needs of high-performance ball screw pair, a new type of reverser must be developed and optimized. [0003] The reverse ball return curve of the ball screw pair is a key factor affecting the performance of the ball screw pair. The quality of the inverter directly affects the noise, vibration, temperature rise, service life and maximum feed speed of the ball screw pair. At present, the end plug inverter is a smooth inverter, which is suitable for low noise, low temperature rise, and high speed ball screw pair. However, the design of the ball return line ...

[0004] The traditional reverser is only a single arc raceway, and its return curve is as follows: image 3 As shown, the traditional reverser ball return raceway includes reverser inlet raceway, single-arc raceway, and reverser outlet raceway, which cannot arbitrarily adjust the circle according to the change of the collision force of the ball in the reverser. The radius of the arc cannot shorten the length of the ball return curve while reducing the collision force
