A bearing with adjustable speed

Abstract

The invention discloses a load-bearing bearing with the adjustable rotating speed, and belongs to the technical field of bearing design. The load-bearing bearing comprises an outer ring, an inner ringand pull rods. Multiple rollers are matched between the outer ring and the inner ring. The rollers comprise balls and cylinders. Each ball comprises a pair of cylinders and a ball body, wherein the two cylinders are connected to the ball body through short shafts. The opposite surfaces of the outer ring and the inner ring are each provided with a circle of screw hole set, and each screw hole setcomprises a same-rotating-speed positioning hole, a hanging plate hole position and a base hole, wherein the hanging plate hole position in each screw hole set is located between the same-rotating-speed positioning hole and the base hole. One end of one pull rod is fixed to one base hole through a bolt, stepped holes are formed in the two ends of the pull rod, a screw of the bolt penetrates through the stepped holes, a thread of a screw section is engaged with the base hole, and the other end of the pull rod is installed in one same-rotating-speed positioning hole or one hanging plate hole position through a bolt. The outer ring and the inner ring of the bearing can be connected and fixed through the detachable pull rods, and therefore same-speed rotating of a driven part and a driving shaft which are connected through the bearing is achieved.

Description

technical field [0001] The invention belongs to the technical field of bearing design, in particular to a load-bearing bearing with adjustable rotational speed. Background technique [0002] Rolling bearing is a part that supports the shaft. It has the purpose of guiding the rotation of the shaft or bearing the idling parts on the shaft. When the bearing is rotated and loaded, the rotation speed of the outer ring of the bearing cannot be controlled. In machining, Objects need to be idling and driven to rotate at a certain speed, and the existing rolling bearings can provide idling, but cannot drive and rotate the load at a constant speed. At this time, the object needs to be directly connected to the object, thereby causing the object to be processed. Not convenient. Contents of the invention [0003] The purpose of the present invention is to provide a load-bearing bearing with adjustable speed. By connecting and fixing the outer ring and the inner ring of the bearing th...
