Novel bearing adapter sleeve

Abstract

The invention discloses a novel bearing adapter sleeve. The novel bearing adapter sleeve comprises an adapter sleeve body, a bearing, a locking nut and a pin shaft; thread segments are connected with a small-diameter end of a conical segment, a tool withdrawal groove is formed in the intersection portion of the thread segments and the conical segment in the circumferential direction, the conical segment is arranged at one end of the adapter sleeve body, the thread segments are arranged at the other end of the adapter sleeve body, the locking nut is arranged on the tool withdrawal groove, and is equal to the tool withdrawal groove in width, the connecting position of the locking nut and the tool withdrawal groove is completely wedged, the bearing is arranged on the conical segment, the locking nut is connected with the bearing, a rotating shaft penetrating the upper end and the lower end of the whole body is arranged in the middle of the adapter sleeve body, the two end faces of the pin shaft are each provided with a first positioning hole, the first positioning holes are symmetric about the rotating shaft, the multiple thread segments extend to the intersection position of the thread segments and the conical segment, the pin shaft is in screw movable connection with the bearing and extends outwards, the fastening effect is reinforced, operation, use and accelerated operation are facilitated, work efficiency is high, the cost is low, and large-range use by the factory is facilitated.

Description

technical field [0001] The invention relates to the field of mechanical parts, in particular to an adapter sleeve for easy disassembly and locking. Background technique [0002] In existing adapter sleeves, the end of the threaded section transitions directly into the cone section. Fasteners are used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, molds, hydraulics, etc., in various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments All kinds of fasteners can be seen on the , chemical industry, instruments and supplies, etc., which are the most widely used mechanical basic parts. There are 4 bearings on the transmission shaft of the barrel mill, and 4 adapter sleeves are used for positioning. According to the positioning principle of the adapter sleeve, when the lock nut is tightened, the lock nut squeezes the bearing, thereby causing a relative displacem...

AI Technical Summary

Problems solved by technology

But when the lock nut is screwed in place, the small end of the inner diameter of the bearing is just aligned with the small end of the tapered surface of the adapter sleeve. At this time, the lock nut cannot be screwed in further, and the bearing can no longer move to the large end of the adapter sleeve, so The bearing cannot be tightened more fully, so axial movement occurs
