Abstract

The invention discloses a biconical roller lead screw pair with large bearing capacity and high rigidity. The biconical roller lead screw pair is mainly composed of a screw rod, a nut and a rolling body, the rolling body is a biconical roller, the biconical roller is a single-biconical roller or a multi-biconical roller, and the single-biconical roller is a biconical rolling body with the large middle and the two small ends. The rolling body of the biconical roller lead screw pair is the biconical roller, the biconical roller is clamped by a V-shaped groove raceway of the lead screw and a V-shaped groove raceway of the nut, bidirectional four-line contact is formed, and the biconical roller lead screw pair has the characteristics of being large in bearing capacity, high in rigidity, high in impact resistance, good in stability, long in service life, light in weight, small in size, high in efficiency, high in precision and the like. Under the same size, compared with a ball screw, the dynamic load of the biconical roller screw pair is improved by about three times, the static load is improved by about five times, the limit moving speed is improved by about two times, and the biconical roller screw pair can replace an existing ball and roller screw pair.

Description

technical field [0001] The invention relates to the field of rolling screws, in particular to a double-tapered roller screw pair with large load and high rigidity. Background technique [0002] At present, the rolling elements used in the existing ball screw are usually balls, which are widely used and the technology is mature. However, the balls and the raceway of the existing ball screw are basically in point contact, with small bearing capacity, low rigidity, weak impact resistance, poor stability, short life, heavy weight, large volume, and low precision. Low. Contents of the invention [0003] The purpose of the present invention is to provide a large-load high-rigidity double-tapered roller screw pair, aiming to solve the problem that the balls and the raceway of the ball screw in the prior art are basically in point contact, the bearing capacity is small, the rigidity is low, Technical problems such as weak impact resistance, poor stability, short life, heavy weig...
