Cylindrical gear tooth backlash adjusting device with bend screw

Abstract

The invention relates to a cylindrical gear tooth backlash adjusting device with a bend screw. The cylindrical gear tooth backlash adjusting device with the bend screw comprises a gear pair, wherein a gear 5 is of an integral type, the other gear consists of a fixed gear 1 and an adjustable gear 2, one end of the fixed gear 1 is provided with a ring boss 11, the adjustable gear 2 sleeves the ring boss 11, one end of an adjusting screw 6 is provided with a bend 61 and is clamped in an axial through hole 21 of the adjustable gear 2, the other end of the adjusting screw 6 is provided with external threads and is spirally connected with a threaded hole in the fixed gear 1, a fastening nut 62 is spirally connected with the outwards extending part of the adjusting screw 6, a locking device comprises a locking screw 7, the locking screw 7 penetrates through a through hole of the fixed gear 1, and the end with the external threads is spirally connected with the threaded hole of the adjustable gear 2. By adopting the structure, the bend 61 drives the adjustable gear 2 to rotate by rotating the screw 6, thus the adjustable gear 2 can rotate for a tiny angle relative to the fixed gear 1 and the adjustment of the tooth backlash is realized.

Description

technical field [0001] The invention relates to the technical field of cylindrical gear transmission, in particular to a device with an elbow screw rod for adjusting the tooth side clearance of a cylindrical gear. Background technique [0002] In cylindrical gear transmission, there will be tooth backlash between the meshing teeth. As the use time goes by, the wear of the gear teeth will increase, and the backlash between the meshing teeth will gradually increase. In mechanical equipment with precision transmission requirements, backlash will seriously affect the accuracy of mechanical equipment operation. [0003] At present, there are generally two methods for adjusting the side clearance of cylindrical gear transmission: first, use the spring force as the loading force to cause an axial displacement of the moving gear relative to the fixed gear to eliminate a pair of cylindrical skew. Backlash of gear transmission. Its working principle: the moving gear is set on the fi...

Problems solved by technology

Because manual rotation cannot rotate evenly and continuously, the adjusted backlash size cannot be controlled, and once the hand loosens the rotating gear and tightens the screw, the backlash may change, so the adjustment accuracy of the backlash is low, and it is returned to the operation It brings inconvenience to the operator and makes the operator's work efficiency low
