Description

The syndeton of motor and shaft coupling
Technical field:
The utility model relates to the syndeton of a kind of motor and shaft coupling.
Background technology:
The syndeton of existing machine shaft and shaft coupling as shown in Figure 1, the outer wall of rotating shaft 11 is provided with external splines, the inwall of shaft coupling 12 is provided with internal spline, external splines and internal spline are cooperatively interacted and shaft coupling 12 are arranged on the output of machine shaft 11 by screw 13 and baffle plate 14, but this mounting connection structure exists following several weak point:
1) production internal spline and external splines need to be equipped with cutter, and the cycle manufacturing cutter is long, and production cost is high, and precision is difficult to be guaranteed, and production efficiency is low;
2) internal spline and external splines need to heat-treat, technique relative complex, and the cycle is long;
3) in use, internal spline and external splines easily wear and tear, and useful life is relatively low.
Summary of the invention:
The purpose of this utility model is to provide the syndeton of a kind of motor and shaft coupling, and this structure is simple, and easily process, production efficiency is high, and reliability is high, long service life.
The purpose of this utility model is achieved by following technical proposals.
The syndeton of motor and shaft coupling, described motor comprises rotating shaft, rotor assembly, stator module, casing and end cap, rotor assembly is arranged in rotating shaft, stator module and casing are installed together and are nested in outside rotor assembly, end cap is arranged on casing end, shaft support is on the bearing of two end cap, and shaft coupling is linked together by the output of expansion sleeve and machine shaft.
The first set cylinder base that expansion sleeve described above comprises annular base and up stretches out in the middle of annular base, shaft coupling stretches out the second receiver, expansion sleeve is sleeved on the output of machine shaft, to be nested in outside first set cylinder base thus shaft coupling and expansion sleeve are installed together by the second receiver.
The outer wall of first set cylinder base described above arranges the first tapering, and the inwall of the second receiver arranges the second tapering, and the first tapering and the second tapering cooperatively interact.
Be installed together by some screws between shaft coupling described above and expansion sleeve, screw is through shaft coupling and to be screwed into inside annular base thus shaft coupling and expansion sleeve are installed together.
The output of machine shaft described above is provided with ring-shaped step, and the bottom surface of annular base is against on ring-shaped step.
The utility model compared with prior art, has following effect:
1) shaft coupling is linked together by the output of expansion sleeve and machine shaft, and this structure is simple, and easily process, production efficiency is high, and reliability is high, long service life;
2) expansion sleeve comprises annular base and from the first set cylinder base up stretched out in the middle of annular base, shaft coupling stretches out the second receiver, expansion sleeve is sleeved on the output of machine shaft, to be nested in outside first set cylinder base by the second receiver thus shaft coupling and expansion sleeve are installed together, structure is simple, easy for installation;
3) outer wall of first set cylinder base arranges the first tapering, and the inwall of the second receiver arranges the second tapering, and the first tapering and the second tapering cooperatively interact, and structure is simple, is connected firmly, reliably, long service life;
4) be installed together by some screws between shaft coupling and expansion sleeve, screw is through shaft coupling and to be screwed into inside annular base thus shaft coupling and expansion sleeve are installed together, and structure is simply, easy for installation, firm.
Accompanying drawing illustrates:
Fig. 1 is the schematic diagram of existing motor and shaft coupling syndeton;
Fig. 2 is stereogram of the present utility model;
Fig. 3 is exploded view of the present utility model;
Fig. 4 is front view of the present utility model;
Fig. 5 is A-A cutaway view in Fig. 4;
