Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a bearing stop device, including axis body conical surface step 1, taper sleeve 2, sleeve 3, double-screw bolt 4, nut 5 and screw 6, there is one section conical surface step for the spiale excircle in axis body conical surface step 1, 2 suits of taper sleeve are on conical surface step 1, 3 suits of sleeve are in 2 excircle departments of taper sleeve, taper sleeve 2 is subdivision structure and through the synthetic whole ring structure of screw 2, taper sleeve 2 and hole have one section to be the taper hole, and there is one end flange structure, all be provided with the screw on its flange face, taper sleeve 2 passes through double-screw bolt 4 and nut 5 and is connected with sleeve 3, sleeve 3 is overall structure, the hole is the step hole, big step hole closely laminates with 2 excircles of taper sleeve, and the terminal surface all is provided with the through-hole, 2 hole conical surfaces of taper sleeve and 1 interference fit of axis body conical.

The working principle is as follows: the limiting device cannot move towards the conical surface direction under the limitation of the connecting shaft conical surface step 1 and the semi-ring conical sleeve 2, and cannot move axially or rotate radially under the limitation of the sleeve 3, the stud 4 and the nut 5; when the limiting device is arranged on the shaft, a fixed step surface is formed to limit the axial movement of the bearing; because this is novel need not to process the recess on the spiale, the spiale body conical surface is a little higher than the axial plane, does not have right angle or closed angle structure, does not influence spiale bulk strength, avoids stress concentration simultaneously to there is the problem that has effectively reduced the increase of axial clearance in the bearing use, improved the life of bearing and axis body.

To sum up, this bearing stop device adopts novel limit structure to make the spiale avoid stress concentration, has effectively reduced the problem of axial clearance increase in the bearing use, has improved the life of bearing and axis body simultaneously, guarantees to produce the line safe and stable operation.
