The utility model will be further described with reference to fig. 1-3.

In order to solve the problems in the background technology, the utility model provides the following technical scheme:

the utility model provides an open and shut nut bearing cap, includes bearing 1, enclosing cover 2 and inner cup 3, and the inner cup 3 is installed on the inner race of bearing 1 for bear the radial impact force that produces when the inner race rotates, the outer lane of bearing 1 is provided with the recess, and the recess shape is annular, installs split nut 4 in the enclosing cover 2, and enclosing cover 2 divide into two halves, and split nut 4's two halves are respectively fixed mounting on two halves of enclosing cover 2, are used for controlling the rotation state of bearing 1 inner race.

Further, the connecting block 5 is fixedly installed on the outer cover 2, the connecting blocks 5 are in threaded connection through the bolts 6, the bolts 6 are rotated, the distance between the outer covers 2 is controlled, the outer ends of the outer covers 2 are sleeved on the outer ring grooves of the bearings 1 through the protruding rings 21, the outer covers 2 can be controlled to abut against the outer rings of the bearings 1 when workers adjust the distance between the outer covers 2, and the outer covers 2 are prevented from being separated.

More specifically, the split nuts 4 are disposed in the inner ring of the bearing 1, and the distance between the outer covers 2 is controlled to control the distance between the split nuts 4 fixedly mounted on the outer covers 2, and the distance between the split nuts 4 is controlled to control the movement state of the inner ring of the bearing 1.

In order to enable the bearing 1 to be connected to an external rotating shaft, a key groove 11 is provided in the inner ring of the bearing 1, and the bearing 1 is connected to the external rotating shaft through the key groove 11.

To illustrate the function of the inner cap 3, a plurality of sets of arc edges 31 are provided on the inner cap 3 and one side of the arc edges 31 is slightly protruded, so that the contact area between the inner cap 3 and the outer cap 2 is reduced, thereby reducing friction between the inner cap 3 and the outer cap 2.
