Description

Shaft end internal spline housing combined member easy to process and replace

Technical Field

The utility model relates to a motor shaft technical field, in particular to axle head internal spline cover built-up member of easily processing, changing.

Background

The motor is used as a power source for underground work of the coal mine, and if problems occur, the efficiency of the underground work can be improved and the coal mine benefit is increased. Therefore, the main engine plant is connected with the main engine through the torque shaft in order to protect the motor, the torque shaft is connected with the main engine in order to protect the motor when the main engine is designed, the motor can be protected when the overload torque shaft is broken, the torque shaft is matched with a motor spline, and although the main engine plant is designed for protection, the motor is good in performance after being used for a long time, and the spline cannot be used due to abrasion.

Disclosure of Invention

In view of the above, there is a need for a shaft end internally splined hub combination member that is easy to machine and replace.

The utility model provides an axle head internal spline cover combined member who easily processes, changes, is including dismantling piece, spline housing, retaining ring and motor shaft, dismantles the piece and the inboard assembly back of spline housing one end, assembles in the one end of motor shaft, and the spline housing outside cooperates with the motor shaft, and the both sides edging of spline housing, both sides edging part processing retaining ring slot, and the retaining ring clamps in the retaining ring slot, and the outside and the motor shaft cooperation of the spline housing other end are fixed through the retaining ring.

Preferably, the recess is seted up to the one end of spline housing, dismantles soon including bellying and main part, bellying and main part integrated into one piece, and bellying and main part center part set up the dismantlement screw, and the bellying cooperates with the recess of spline housing, adopts the screw and dismantles the screw cooperation fixed.

When the motor shaft is machined, the requirement on the coaxiality of the spline sleeve and the motor shaft can be met as long as the requirement on the coaxiality of the inner hole of the motor shaft and a reference is well controlled according to the matching size of the spline sleeve, and the positioning spline sleeve groove and the retainer ring groove are easy to machine. This kind of structure is the groove of the inboard processing both sides edge milling of conventional motor shaft, non-circumference groove, and easy to operate is convenient for process the location benchmark, and is lower to the requirement of processing equipment, so, the utility model discloses processing motor that can be swift improves motor manufacturer's maneuverability simultaneously because of the problem that spline wearing and tearing can not use.

in the figure: the dismounting device comprises a dismounting block 1, a convex part 10, a main body part 11, a spline housing 2, a check ring 3, a motor shaft 4, a check ring groove a, a groove b and a dismounting screw hole c.

Detailed Description

In order to make the technical solution of the present invention easier to understand, the present invention adopts the mode of the specific embodiment with reference to the attached drawings, and the technical solution of the present invention is clearly and completely described.

Referring to fig. 1, fig. 2, fig. 3 and fig. 4, the shaft end internal spline housing combined member easy to process and replace includes a dismounting block 1, a spline housing 2, a retainer ring 3 and a motor shaft 4, after the dismounting block 1 is assembled with the inner side of one end of the spline housing 2, the dismounting block is assembled at one end of the motor shaft 4, the outer side of the spline housing 2 is matched with the motor shaft 4, both sides of the spline housing 2 are chamfered, retainer ring grooves a are processed at both sides of the chamfered portions, the retainer ring 3 is clamped in the retainer ring grooves a, and the outer side of the other end of the spline housing 2 is matched with the motor shaft 4 and is fixed by the retainer ring 3.

The groove b is formed in one end of the spline housing 2, the dismounting block 1 comprises a protruding portion 10 and a main body portion 11, the protruding portion 10 and the main body portion 11 are integrally formed, dismounting screw holes c are formed in the center of the protruding portion 10 and the center of the main body portion 11, the protruding portion 10 is matched with the groove b of the spline housing 2, and the spline housing is fixed in a matched mode through screws and the dismounting screw holes c. The spline of the inner side of the spline housing 2 is matched with the torque shaft, the cylindrical part of the outer side is in small clearance fit with the motor shaft 4, and the retaining ring grooves a machined on the chamfered edges at both sides and the chamfered edge parts at both sides are fixed with the corresponding parts of the motor shaft 4 through retaining rings 3.

When the motor shaft is machined, as long as the requirement on the coaxiality of the inner hole of the motor shaft and the reference is well controlled as to the matching size of the spline sleeve, the reference is set to be 0.04A in diameter, the requirement on the coaxiality of the spline sleeve and the motor shaft can be met, and the positioning spline sleeve groove and the retainer ring groove are easy to machine. This kind of structure is the groove of the inboard processing both sides edge milling of conventional motor shaft, non-circumference groove, and easy to operate is convenient for process the location benchmark, and is lower to the requirement of processing equipment, so, the utility model discloses processing motor that can be swift improves motor manufacturer's maneuverability simultaneously because of the problem that spline wearing and tearing can not use.

It should be noted that the embodiments described herein are only some of the embodiments of the present invention, not all implementations of the present invention, and the embodiments are only exemplary, and only serve to provide a more intuitive and clear way to understand the contents of the present invention, but not to limit the technical solutions of the present invention. Without departing from the concept of the present invention, all the other embodiments that can be conceived by those skilled in the art without creative efforts, and other simple replacements and various changes to the technical solution of the present invention, all belong to the protection scope of the present invention.
