Abstract
The utility model provides a first straight burr face and second straight burr face are formed, this internal axially extending bore that is equipped with of axle sleeve, and the axially extending bore both ends are equipped with first straight burr face and second straight burr face respectively that titanium alloy central hub, by the axle sleeve body and set up in axle sleeve body both sides first straight burr face and second straight burr face on all be equipped with the straight burr, first straight burr face and second straight burr face encircle into the ring form through its surperficial straight burr separately, straight burr direction and axially extending bore direction unanimity, wherein, the central line of axle sleeve body, first straight burr face and second straight burr face is point -blank, the outside diameter of first straight burr face is 0.8 times of outside diameter of axle sleeve body, and the outside diameter of second straight burr face is 0.9 times of outside diameter of axle sleeve body, and the straight burr length of first straight burr face is 1.2~1.5 times of straight burr length of second straight burr face, first straight burr face and second straight burr face are equipped with the recess respectively on the contact surface with the axle sleeve body, the other end of first straight burr face and second straight burr face all is equipped with the chamfer, and the chamfer is 15~30.
Description
Technical field:
This use is novel relates to a kind of central axle sleeve, particularly relates to a kind of titanium alloy central axle sleeve.
Background technology:
Central axle sleeve be a kind of bearing surface that is arranged in order to slide and to protect the standard component of bearing, have a wide range of applications in production equipment.In existing central axle sleeve, when bearing is given a shock or during external force, the axle center axle sleeve of bearing surface is very easily lax or comes off, and not only have impact on the normal operation of bearing, also loses slip and the defencive function of central axle sleeve, bring inconvenience to user.
Utility model content:
For the deficiency of above-mentioned technology, this utility model devises a kind of titanium alloy central axle sleeve, by sleeve body and be arranged on the first ruled surface of sleeve body both sides and the second ruled surface forms.
This utility model solves to be provided with axially extending bore in the technical scheme is that sleeve body of its technical problem, axially extending bore is respectively arranged at two ends with the first ruled surface and the second ruled surface, the first described ruled surface and the second ruled surface are equipped with straight burr, first ruled surface and the second ruled surface each encompass circular by the straight burr on its surface, straight burr direction is consistent with axially extending bore direction, wherein, the centrage of sleeve body, the first ruled surface and the second ruled surface is point-blank；The outside diameter of the first ruled surface is 0.8 times of the outside diameter of sleeve body, and the outside diameter of the second ruled surface is 0.9 times of the outside diameter of sleeve body, 1.2～1.5 times of the straight burr length that straight burr length is the second ruled surface of the first ruled surface；First ruled surface and the second ruled surface with the contact surface of sleeve body on be respectively equipped with groove, the other end of the first ruled surface and the second ruled surface is equipped with chamfering, and chamfering is 15 °～30 °.
The beneficial effects of the utility model: prevent axle sleeve lax or come off.
Accompanying drawing illustrates:
Fig. 1 is main TV structure figure of the present utility model；
Wherein, 1-sleeve body, 2-the first ruled surface, 3-the second ruled surface.
Detailed description of the invention:
This utility model devises a kind of titanium alloy central axle sleeve, by sleeve body and be arranged on the first ruled surface of sleeve body both sides and the second ruled surface forms, axially extending bore it is provided with in sleeve body, axially extending bore is respectively arranged at two ends with the first ruled surface and the second ruled surface, the first described ruled surface and the second ruled surface are equipped with straight burr, first ruled surface and the second ruled surface each encompass circular by the straight burr on its surface, straight burr direction is consistent with axially extending bore direction, wherein, the centrage of sleeve body, the first ruled surface and the second ruled surface is point-blank；The outside diameter of the first ruled surface is 0.8 times of the outside diameter of sleeve body, and the outside diameter of the second ruled surface is 0.9 times of the outside diameter of sleeve body, 1.2～1.5 times of the straight burr length that straight burr length is the second ruled surface of the first ruled surface；First ruled surface and the second ruled surface with the contact surface of sleeve body on be respectively equipped with groove, the other end of the first ruled surface and the second ruled surface is equipped with chamfering, and chamfering is 15 °～30 °.
This utility model by being respectively provided with the first ruled surface and the second ruled surface in the both sides of sleeve body, effectively increase the friction between the standard component on central axle sleeve and bearing, prevent the central axle sleeve caused because of vibrations or transient cause from relaxing or coming off, very easy to use.
Claims (2)
