Problems solved by technology

However, especially when the lock nut is installed on the main shaft, the locking torque of the lock nut provides an axial force to the main shaft bearing to maintain the proper clearance of the main shaft bearing, but the lock nut often fails due to centrifugal force after working for a period of time. And loose, causing the spindle bearing to fail, which will cause serious damage to the spindle system
This kind of failure occurs frequently, and the time cost and economic cost required for repair are high

Embodiment Construction

[0029] figure 1 A side view of a cage nut assembly according to a preferred embodiment of the present invention is shown. The lock nut assembly includes two lock nuts that fit together in the axial direction, that is, a first lock nut 1 and a second lock nut 2 . The first lock nut 1 and the second lock nut 2 together form a substantially circular lock nut assembly. Such as figure 1 As shown, the first lock nut 1 and the second lock nut 2 have the same shape, and both are non-rotationally symmetrical structures. The first lock nut 1 and the second lock nut 2 have coaxial central holes with the same diameter, and internal threads (not shown) are all provided in each central hole, and the internal thread of the central through hole of the lock nut assembly is Consistent and continuous. exist figure 1 The axial end face of the second lock nut 2 can be clearly seen in . figure 2 shows the basis figure 1 A side view of the union nut from another angle, namely showing the axi...

Abstract

The invention relates to a lock nut assembly for a rotating shaft (6) and a method for assembling the lock nut assembly. The lock nut assembly has a rotation axis, wherein the center of mass of the lock nut assembly is located on the rotation axis; the lock nut assembly comprises two lock nuts (1 and 2) which abut against each other, wherein the centers of mass of the lock nuts (1 and 2) deviate from the rotation axis, and due to the positions of the centers of mass, when the lock nuts (1 and 2) rotate with the rotating shaft (6), the centrifugal force of the lock nuts (1 and 2) generates a torque which can press the lock nuts (1 and 2) to the rotating shaft (6).

Description

technical field [0001] The invention relates to a lock nut assembly, in particular to a lock nut assembly for a main shaft bearing. The present invention relates to a method for assembling a cage nut assembly. Background technique [0002] The lock nut can be used to position and fix the fixed parts such as bearings installed on the shaft. The lock nut has a locking mechanism so that even if there is a gap between the lock nut and the fastening surface due to vibration or impact, it will not Looseness occurs. [0003] In the prior art, various measures are taken to prevent the nut from loosening. For example, two identical nuts are screwed on the same bolt, and an additional tightening torque is added between the two nuts to make the bolts reliably connected. Alternatively, a lock nut can be used in conjunction with a lock washer. Another solution is to form a lock nut with two parts. For example, in the patent document US 6,609,867 B2, a lock nut is taught, wherein each...
