Abstract
The utility model discloses the anti-retraction means of a kind of torque axis, and torque axis can slide in main shaft; The end of described torque axis arranges groove, and the outside of described groove is fixedly installed pallet, and the centre position of described pallet arranges through hole, and one end of pull bar is fixed on the bearing in described groove through after described through hole; Other one end of pull bar is through fixing with handle after the spacing hole of fixed cap; Pallet arranged outside spacing collar; Rod outer sleeve between pallet and spacing collar has spring; Spacing collar arranged outside backing pin, the external diameter of backing pin is less than the internal diameter of spacing hole; The external diameter of spacing collar is greater than the internal diameter of described spacing hole.The utility model has the advantages that: utilize spring to produce thrust and guarantee that spacing collar and backing pin are tightly fixed on the both sides of fixed cap, limited the axial and radial displacement of torque axis, solved when unit is overhauled because unit produces vibration, make Motor torque axle automatically return and mesh, thereby safety in production is brought to the technical problem of hidden danger.
Description
Technical field
The utility model relates to electric motors, is on the motor using with torque axis arrangement of clutch motor specifically.
Background technology
Motor in use will now need to make the torque axis of motor and main shaft to depart to machinery check and repair, makes the unpowered input of motor, thereby unit is overhauled.Because unit produces vibration, this vibrational energy makes Motor torque axle automatically return and mesh, thereby safety in production is brought to hidden danger.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide the anti-retraction means of a kind of torque axis, and concrete technical scheme is as follows:
The anti-retraction means of torque axis, is characterized in that: comprise torque axis, main shaft, pallet, spring, spacing collar, backing pin, pull bar, fixed cap, handle, described torque axis can slide in main shaft; The end of described torque axis arranges groove, and the outside of described groove is fixedly installed pallet, and the centre position of described pallet arranges through hole, and one end of described pull bar is fixed on the bearing in described groove through after described through hole; Other one end of described pull bar is through fixing with handle after the spacing hole of fixed cap; Described pallet arranged outside spacing collar; Rod outer sleeve between pallet and spacing collar has spring; Described spacing collar arranged outside backing pin, the external diameter of described backing pin is less than the internal diameter of described spacing hole; The external diameter of described spacing collar is greater than the internal diameter of described spacing hole.
Described fixed cap arranges strip-shaped clamp groove.
The utility model has the advantages that: utilize spring to produce thrust and guarantee that spacing collar and backing pin are tightly fixed on the both sides of fixed cap, limited the axial and radial displacement of torque axis, solved when unit is overhauled because unit produces vibration, make Motor torque axle automatically return and mesh, thereby safety in production is brought to the technical problem of hidden danger.Processing technology is simple, and cost is low, can be used for various motors, has higher economy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the utility model is used view;
Fig. 3 is fixed cap structural representation;
In figure, 1. torque axis; 2. main shaft; 3. pallet; 4. spring; 5. spacing collar; 6. backing pin; 7. pull bar; 8. bearing end cover; 9. fixed cap; 10. shake hands; 11. spacing holes; 12. strip-shaped clamp groove.
Embodiment
Below in conjunction with accompanying drawing, illustrate the utility model, as shown in Figure 1-Figure 3, comprise torque axis 1, main shaft 2, pallet 3, spring 4, spacing collar 5, backing pin 6, pull bar 7, fixed cap 9, handle 10, described torque axis 1 can be in the interior slip of main shaft 2; The end of described torque axis 1 arranges groove, and the outside of described groove is fixedly installed pallet 3, and the centre position of described pallet 3 arranges through hole, and one end of described pull bar 7 is fixed on the bearing in described groove through after described through hole; Other one end of described pull bar 7 is rear fixing with handle 10 through the spacing hole 11 of fixed cap 9; Described pallet 3 outsides (right side of Fig. 1) arrange spacing collar 5; Pull bar 7 overcoats that pallet 3 and spacing collar are 5 have spring 4; Described spacing collar 5 arranged outside backing pins 6, the external diameter of described backing pin 6 is less than the internal diameter of described spacing hole 11; The external diameter of described spacing collar 5 is greater than the internal diameter of described spacing hole 11.
Described fixed cap 9 arranges strip-shaped clamp groove 12.
Principle of the present utility model is, when needs torque axis 1 departs from main shaft 2, pulls out handle 10, and it drives pull bar 7 and torque axis 1 outwards to move together, as shown in Figure 2.When backing pin 6 is by after the spacing hole 11 of fixed cap 9, spacing collar 5 Compress Springs 4 also produce thrust, handle 10 drives pull bar 7 and backing pin 6, half-twist, and backing pin 6 is placed in the strip-shaped clamp groove 12 of fixed cap 9 (Fig. 3), now spring is compressed, thereby torque axis can not be moved axially, can not rotate, torque axis 1 is fixed like this.
Claims (2)
1. the anti-retraction means of torque axis, is characterized in that: comprise torque axis, main shaft, pallet, spring, spacing collar, backing pin, pull bar, fixed cap, handle, described torque axis can slide in main shaft; The end of described torque axis arranges groove, and the outside of described groove is fixedly installed pallet, and the centre position of described pallet arranges through hole, and one end of described pull bar is fixed on the bearing in described groove through after described through hole; Other one end of described pull bar is through fixing with handle after the spacing hole of fixed cap; Described pallet arranged outside spacing collar; Rod outer sleeve between pallet and spacing collar has spring; Described spacing collar arranged outside backing pin, the external diameter of described backing pin is less than the internal diameter of described spacing hole; The external diameter of described spacing collar is greater than the internal diameter of described spacing hole.
2. the anti-retraction means of torque axis according to claim 1, is characterized in that: described fixed cap arranges strip-shaped clamp groove.
