Adapter sleeve easy to detach

Abstract

The invention discloses an adapter sleeve easy to detach comprising a locking nut, a positioning ring and a rotating shaft. A mounting part is arranged on the rotating shaft. The positioning ring is arranged on the left side of the mounting part. The locking nut is arranged on the right side of the mounting part. A conic hole self-aligning bearing is arranged on the inner side of the mounting part. A strain groove and a sleeve are fixed below the mounting part. A cylindrical shaft is fixed between the strain groove and the sleeve. A spring is fixed on the right side of the cylindrical shaft. A hand rocking rotating handle is arranged on the right side of the spring. A thread part is fixed on the sleeve. An adapter screw is fixed inside the locking nut. Adapter threads are arranged on the lower portion of the adapter screw and the upper portion of the thread part. A chamfer is arranged on the upper portion of the locking nut. A locking spacer is arranged between the mounting part and the locking nut. By arranging the locking nut, the conic hole self-aligning bearing is convenient to mount, the machining difficulty of the rotating shaft is reduced, matching of the conic face of the locking nut and the conic hole self-aligning bearing is good, operation is easy, the cost is low, and working efficiency is high.

Description

Technical field [0001] The technical field of the adapter sleeve of the present invention is specifically an easy-to-disassemble adapter sleeve. Background technique [0002] In the existing technology, the adapter sleeve is mostly installed mechanically on the rotating shaft, and the adapter sleeve is tightened against the tapered hole self-aligning bearing through the tightening nut. The mechanically installed adapter sleeve is not installed tightly enough, and tools need to be used during installation. Beating, therefore, can easily lead to damage to the adapter sleeve, greatly affecting its accuracy and making it impossible to disassemble or reuse the adapter sleeve. According to the positioning principle of the adapter sleeve, when the locking nut is tightened, the locking nut squeezes the bearing, causing relative displacement between the bearing and the adapter sleeve. The greater the displacement, the better the tightening effect, so theoretically This form of assem...

AI Technical Summary

Problems solved by technology

However, in the prior art, 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. Movement, so the bearing cannot be tightened more fully, so axial movement occurs

In addition, the design of the bearing tightening device in the prior art is unreasonable, and the installation and disassembly are not very convenient
