Embodiment Construction

[0013] The low-noise ball screw pair of the present invention will be further described below in conjunction with the accompanying drawings.

[0014] Such as Figure 1-2 The low-noise ball screw pair shown includes a screw 1, a nut 2, and a ball 3. The above-mentioned screw 1 is provided with a screw raceway 11, and the above-mentioned nut 2 is internally provided with a nut internal thread raceway 21. , the difference is that the above-mentioned balls 3 are embedded in the elastic isolation chain 4, and the balls 3 are arranged in sequence to form a chain-like rolling body, and placed in the above-mentioned screw raceway 11 and nut internal thread raceway 21.

[0015] An oil storage cavity 5 is built inside the link of the above-mentioned elastic isolation chain 4, and lubricating grease is placed in the above-mentioned oil storage cavity 5. Above-mentioned elastic isolation chain is plastic or rubber or rubber-plastic material.

[0016] When working, the screw 1 is driven ...

Abstract

The invention discloses a ball screw with low noise, including a lead screw, a nut, a ball, wherein the lead screw is arranged with lead screw race, and the inner of the nut is provided with a nut inner worm race, characterized in that, the ball is embedded in the elastic separating chain, and the ball is arranged in sequence to form the chain rolling element and arranged in the lead screw and the nut internal thread race. The ball screw does not generate the friction to cause overheat between the balls with advanced precision, low noise, stable movement, long service life.

Description

technical field [0001] The invention relates to a mechanical transmission technology, more specifically to a transmission device of a screw and nut mechanism for mechanical transmission. Background technique [0002] The ball screw pair is the key component of the key function of precision mechanical transmission. In recent years, with the higher and higher requirements for the accuracy of machine tool functions, the requirements for the ball screw pair are also getting higher and higher. The existing ball screw pair mainly includes a screw, a nut, and balls. The balls roll in the cavity formed between the screw raceway and the nut internal thread raceway, so that the linear motion is converted into rotary motion, or the rotary motion is converted into Linear motion, due to the certain error between the screw raceway and the nut internal thread raceway during processing, the ball is in point contact or line contact with the screw raceway and the nut internal thread raceway d...
