Abstract
The utility model relates to a hollow axle with an inner spline. The utility model is characterized in that a main body (1) is a through hole whose end without internal spline is provided with internal thread matching a pipe plug (2). The combined hollow axle with inner spline has the advantages of simple processing, good processing smoothness, high precision, high productive efficiency, small conicity of the hole from 0.03 to 0.05 mm, and low cost. The utility model can adopt advanced computer autocontrol wire cut machining process, suitable for high-speed mechanical transmission.
Description
The utility model relates to the mechanical transmission hollow shaft, is the highi degree of accuracy internal spline hollow shaft that uses in a kind of high speed machine transmission.
At present, the internal spline hollow shaft that uses on the dry method eyeball synthetic fibre spinning equipment crimping machine of U.S.'s import is one, and endoporus is a blind hole, sees accompanying drawing 1.Its design shortcoming is an internal spline involute processing difficulties, and problem is as follows:
One, with common process method such as gear shaping, heat treatment again after surviving, distortion is big, and degree of finish is low, low precision.
Two, the internal spline hollow shaft of U.S.'s import is to adopt electrical pulse processing, and its manufacturing efficiency is low, the cost height, and hole taper is bigger, and actual measurement CONCENTRIC REDUCER error is 0.06～0.08mm.
The purpose of this utility model is: provide a kind of internal spline hollow shaft, to solve former internal spline hollow shaft processing difficulties, cost height, problems such as low precision.
The purpose of this utility model is achieved in that this internal spline hollow shaft is made of main body, and main body is a through hole, is provided with internal thread at its no internal spline end, is provided with plug with screw-internal thread fit.
This model utility compared with prior art has the following advantages: the utility model is because of changing former internal spline hollow shaft one into two combinations, and main body changed be designed to through hole, easy to process, main body after heat treatment earlier can adopt advanced computer to control automatically at the bottom of the profile of tooth of involute in the wire cutting technology cutting, tooth root, the tooth.Its degree of finish is good, the precision height, and the manufacturing efficiency height, hole taper is little, is 0.03～0.05mm, and analysis cost is the of import like product.
Be described further below in conjunction with accompanying drawing:
Fig. 1: the utility model internal spline hollow shaft structure schematic representation;
Fig. 2: the utility model internal spline hollow shaft C is to view;
Fig. 3: former U.S. import internal spline hollow shaft structure schematic representation.
At Fig. 1--in 2, main body (1) is a through hole, is provided with internal thread at its no internal spline end, and screw-thread fit has plug (2).Plug (2) periphery is provided with outside thread, and its exterior edge face is provided with two symmetrical blind holes, to protect former blind interior hole shape and usability.
Main body among Fig. 3 (1) is one, is blind hole.
Claims (2)
1, a kind of internal spline hollow shaft is to be made of main body (1), it is characterized in that: main body (1) is provided with internal thread for through hole at its no internal spline end, with screw-internal thread fit plug (2) is arranged
2, internal spline hollow shaft according to claim 1 is characterized in that: plug (2) periphery is provided with outside thread, and its exterior edge face is provided with two symmetrical blind holes.
