Abstract
The utility model provides the combination of a worm and a shaft of a hanging-basket motor, wherein shaft hole knurl interference fit and end riveting technology are employed to inward press one end of the worm along own step to an outward convex step of a motor rotor shaft for connecting by riveting. Axial movement between the motor rotor shaft and the worm the can be effectively stopped by using the method of worm shaft hole knurl interference fit and the method of end riveting. As the motor rotor shaft and the worm are in a sleeved connecting composite structure, so that the diameter of the worm is increased, namely the size of the worm teeth is increased, the intensity and the self-locking strength of the worm teeth are increased, the service life is prolonged, and the efficiency is improved.
Description
Affiliated technical field
The utility model relates to worm screw and axle, particularly relates to the worm screw of hanging-basket motor and the combination of axle.
Background technology
Hanging-basket motor mainly is used in the low weight goods and materials of lifting weight on the mine, but its power output main shaft is the same with other direct current machines, rotor axis of electric and worm screw entire body are made, because the worm screw diameter is less, and the tooth thinner thickness, intensity is low, because tooth is too little, too little with the field of conjugate action of worm gear, self-lock force is inadequate again, fragile, thus working life affected.
Summary of the invention
The worm screw of the hanging-basket motor of the defectives such as the purpose of this utility model is to provide a kind of worm tooth intensity difference that solves hanging-basket motor, and the self-locking dynamics is little and the combination of axle.
The purpose of this utility model is reached by following technical scheme: it comprises rotor axis of electric and worm screw, and wherein said worm screw has hollow hole and described axle is complementary.The outer cylinder surface of described axle has axially rolled anti-skid design, is with the hollow hole inner surface of described worm screw to be closely connected, and the engagement that an end of the hollow hole of described worm screw is provided with indent becomes to be connected with a joggle with the side, evagination rank of described rotor axis of electric along rank.
The utility model is completed by following process: first the outer cylinder surface with rotor axis of electric uses machine tooling to become axial annular knurl decorative pattern, be pressed in the hollow hole of pre-processed worm screw, one-tenth closely cooperates, and then with the riveted of worm screw one end along rank inwardly the evagination rank riveted of pressurization and rotor axis of electric be connected.
Use the technical solution of the utility model that following advantage is arranged:
1, owing to adopting rotor axis of electric and worm screw socket combining structure, strengthened the diameter of worm screw, namely strengthened the size of worm tooth, strengthened intensity and the self-locking dynamics of worm tooth, working life increases, and has improved efficient.
2. adopted axis hole annular knurl interference fit and termination riveting process, worm screw one end riveted inwardly has been pressed on the evagination rank riveted connection of rotor axis of electric along rank.Adopt the method for worm screw axis hole annular knurl interference fit and termination riveted joint, can effectively stop moving axially, coming off between rotor axis of electric and worm screw, the ectonexine relative sliding can be avoided breaking down, and increases the service life.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing and embodiment
Fig. 1 is the structural representation of the utility model embodiment
Fig. 2 is for using the hanging-basket motor schematic diagram of the utility model embodiment
Number in the figure explanation: 5. rotor axis of electric, 4. riveted along rank, 3. rotor axis of electric butt end, 2. worm screw, 1. rotor axis of electric taper end.
Embodiment
The rotor beam warp worm screw combination of hanging-basket motor connects with worm gear, its rotor axis of electric worm combined mechanism is: rotor axis of electric 5 overcoats have the worm screw 2 of hollow, rotor axis of electric 5 is divided into two parts in the hollow hole of worm screw 2: a part is thick section 3 of rotor axis of electric, a part is the taper end 1 of rotor axis of electric, the thick section 3 of rotor axis of electric and motor shaft thin segment 1 outer cylinder surface are processed into the annular knurl line, and the hollow hole of worm screw 2 is also with corresponding porose thick section and porose thin segment and mate with the rotor axis of electric outside cylinder.The connection that becomes to closely cooperate of the hollow hole of rotor axis of electric thick section 3 external cylindrical surfaces and rotor axis of electric thin segment 1 external cylindrical surface and worm screw 2, thick section of corresponding hole and hole thin segment.The riveted that is provided with indent in the termination, the inside of worm screw 2 is along rank 4, after rotor axis of electric 5 and worm screw 2 sockets, becomes the riveted connection through technique for riveting with the thick section of a rotor axis of electric side, rank.
After adopting technical pattern provided by the utility model, owing to adopting rotor axis of electric and worm screw socket combining structure, strengthened the diameter of worm screw, namely strengthened the size of worm tooth, strengthened intensity and the self-locking dynamics of worm tooth, working life increases, and has improved efficient.
Claims (1)
1. the combination of the worm screw of a hanging-basket motor and axle, comprise rotor axis of electric and worm screw, it is characterized in that: described worm screw has hollow hole and matches with described rotor axis of electric, the outer cylinder surface of described rotor axis of electric is provided with the annular knurl decorative pattern, be to closely cooperate with the hollow hole internal circular surfaces of described worm screw and connect, the riveted that one end of the hollow hole of described worm screw is provided with indent is along rank, and becomes to be connected with a joggle in the side, evagination rank of described rotor axis of electric.
