Abstract
The utility model relates to a machinery dismounting device technical field, especially an abrasionproof type draws horse. It includes the lead screw, draw the seat, transport persons or goods by cart and draw the claw, and the lead screw is inserted in the central authorities of drawing the seat, transports persons or goods by cart and connects the edge drawing the seat, draws the claw to connect at the end of transporting persons or goods by cart, is equipped with sheath, two -way thrust ball bearing and cushion on the lead screw, draws and is equipped with pull ring and thrust roller bearing on the seat. Set up sheath, two -way thrust ball bearing and cushion on the lead screw, set up pull ring and thrust roller bearing on drawing the seat, accessible slewing mechanism inside and outside the formation. The during operation, the radial revolving force of lead screw is blocked by two -way thrust ball bearing to be dissolved, can't pass on the cushion, has avoided the wearing and tearing of lead screw to the axis body, simultaneously, draws the radial revolving force of seat production under the influence of lead screw to be blocked by thrust roller bearing and dissolves, can't pass on the pull ring, has avoided drawing the claw to the wearing and tearing of wheel body, has guaranteed the integrality of work piece.
Description
Technical field
The utility model relates to mechanical provision for disengagement technical field, and especially a kind of wear-resistance draws horse.
Background technology
In machinery industry, often relate to motor pulley, stator, rotor and the field-strip between various gear and axle in motor, need to use a kind of instrument being referred to as to draw horse.Form screw mechanism between its nut and screw mandrel, nut is fixed in main body, and after the front end of pulling claw is linked up with gear hook jail, turn screw mandrel makes its front end and is coupling tactile and continues forward to withstand axle, and wheel shaft can be made to be separated.Existing when drawing horse to work screw mandrel withstand on axle, implement pulling force by radial rotary, wearing and tearing in various degree can be caused to axis body and wheel body, affect the integrality of workpiece.
Utility model content
Existingly draw horse axis body easy to wear and wheel body to overcome, affect the deficiency of workpiece integrality, the utility model provides a kind of wear-resistance and draws horse.
The utility model solves the technical scheme that its technical problem adopts: a kind of wear-resistance draws horse, comprise screw mandrel, pulling seat, transport persons or goods by cart and pulling claw, screw mandrel is inserted in the central authorities of pulling seat, transport persons or goods by cart and be connected to the edge of pulling seat, pulling claw is connected to the end of transporting persons or goods by cart, screw mandrel is provided with sheath, double-direction thrust ball bearing and cushion block, and pulling seat is provided with draw ring and thrust roller bearing, transports persons or goods by cart and is connected on draw ring.
According to another embodiment of the present utility model, comprise the two ends up and down that sheath and cushion block are connected to double-direction thrust ball bearing further.
According to another embodiment of the present utility model, the bottom comprising screw mandrel is further inserted in sheath.
According to another embodiment of the present utility model, comprise draw ring further and thrust roller bearing is all enclosed within pulling seat, draw ring is positioned at the top of thrust roller bearing.
The beneficial effects of the utility model are, screw mandrel arranges sheath, double-direction thrust ball bearing and cushion block, double-direction thrust ball bearing is installed between sheath and cushion block, pulling seat arranges draw ring and thrust roller bearing, thrust roller bearing is installed between draw ring and pulling seat, forms inside and outside accessible rotating mechanism.During work, the radial rotary power of screw mandrel is blocked by double-direction thrust ball bearing and is dissolved, cushion block cannot be relayed to, avoid the wearing and tearing of screw mandrel to axis body, meanwhile, the radial rotary power that pulling seat produces under the impact of screw mandrel is blocked by thrust roller bearing and is dissolved, and cannot be relayed to draw ring, avoid the wearing and tearing of pulling claw to wheel body, ensure that the integrality of workpiece.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure, 1. screw mandrels, 2. pulling seat, 3. transport persons or goods by cart, 4. pulling claw, 5. sheath, 6. double-direction thrust ball bearing, 7. cushion block, 8. draw ring, 9. thrust roller bearing.
Detailed description of the invention
If Fig. 1 is structural representation of the present utility model, a kind of wear-resistance draws horse, comprise screw mandrel 1, pulling seat 2, transport persons or goods by cart 3 and pulling claw 4, screw mandrel 1 is inserted in the central authorities of pulling seat 2, to transport persons or goods by cart 3 edges being connected to pulling seat 2, pulling claw 4 be connected to transport persons or goods by cart 3 end, screw mandrel 1 is provided with sheath 5, double-direction thrust ball bearing 6 and cushion block 7, pulling seat 2 is provided with draw ring 8 and thrust roller bearing 9, transports persons or goods by cart 3 to be connected on draw ring 8.Sheath 5 and cushion block 7 are connected to the two ends up and down of double-direction thrust ball bearing 6.The bottom of screw mandrel 1 is inserted in sheath 5.Draw ring 8 and thrust roller bearing 9 are all enclosed within pulling seat 2, and draw ring 8 is positioned at the top of thrust roller bearing 9.
Screw mandrel 1 arranges sheath 5, double-direction thrust ball bearing 6 and cushion block 7, double-direction thrust ball bearing 6 is installed between sheath 5 and cushion block 7, pulling seat 2 arranges draw ring 8 and thrust roller bearing 9, and thrust roller bearing 9 is installed between draw ring 8 and pulling seat 2, forms inside and outside accessible rotating mechanism.During work, the radial rotary power of screw mandrel 1 is blocked by double-direction thrust ball bearing 6 and is dissolved, cushion block 7 cannot be relayed to, avoid the wearing and tearing of screw mandrel 1 pair of axis body, meanwhile, the radial rotary power that pulling seat 2 produces under the impact of screw mandrel 1 is blocked by thrust roller bearing 9 and is dissolved, and cannot be relayed to draw ring 8, avoid the wearing and tearing of pulling claw 4 pairs of wheel bodys, ensure that the integrality of workpiece.
