Detailed Description

Example 1:

referring to fig. 1-2, the utility model discloses a bearing mounting and cap locking device, which comprises a bearing seat 1, a bearing 2, a shaft 3 and a locking and cap 4; the locking nut 4 is provided with a fastening screw 5 and a force increasing rod 6 which are matched with the locking nut;

the bearing 2 is fixed on the bearing seat 1 and sleeved on the periphery of the shaft 3, the locking nut 4 is also sleeved on the periphery of the shaft 3 and arranged side by side with the bearing 2, and the locking nut is rotationally locked to abut against the inner ring of the bearing 2 through the threads on the shaft during installation;

one end of the locking nut 4 is provided with a counter bore 41 which is matched with the fastening screw 5 and the force increasing rod 6. The number of the counter bores 41 and the number of the fastening screws 5 are two, and the counter bores and the fastening screws are symmetrically arranged on two sides of the shaft 3.

The counter bore 41 is divided into a rod hole 411 and a screw hole 412 from top to bottom; the rod hole 411 communicates with the screw hole 412. The diameter of the rod hole 411 is matched with the outer diameter of the force increasing rod 6, and the rod hole is used for accommodating the end part of the force increasing rod 6 to be inserted and not to shake; the screw hole 412 has an inner diameter that fits the set screw 5 for accommodating the screwing-in of the set screw 5. And the bearing seat 1 is also provided with a hole clamp spring 7 for blocking the locking bearing.

The working process is as follows:

firstly, a bearing 2 and a locking nut 4 which are fixed on a bearing seat 1 are sequentially sleeved on the periphery of a shaft 2, the locking nut 4 is rotationally locked through a thread on the shaft and abuts against the inner ring of the bearing 2, a force increasing rod 6 is inserted into a rod hole 411 of a counter bore 41 of the locking nut 4 to play a role of rotationally locking and the nut 4 rotates relative to the shaft, and the bearing 2 is pushed to be rotationally pressed into a bearing gear position while the shaft 2 rotates as a center; after the bearing 2 is installed in place, the force increasing rod 6 is removed; the fastening screw 5 is screwed into the screw hole 412 of the counter bore 41 of the locking nut 4, so that the locking nut 4 is fixed to the shaft 2 without loosening.
