A bearing pressing mechanism

Abstract

A bearing press-in mechanism of the present invention comprises: a support base, a retaining sleeve and a push-in mechanism; the support base is formed by connecting a pair of baffles through double-headed studs around them, and the gap between the baffles and the baffles is There is a gap; a bushing is installed in the through hole in the center of the upper surface of the support seat, and the bushing can fit the push-in mechanism with clearance; the end of the push-in mechanism is facing the thrust of the lower surface of the support seat hole; the front end of the push-in mechanism is equipped with a stopper; the stopper is fixed on the upper surface of the support seat under the action of the fastener. Through the above method, a bearing press-in mechanism is provided, which can adjust the spacing of the support seats according to different types of bearings, and can also optimize the press-in process of the bearings with the shift sleeve. And use the block to fix the bearing parts, adopt the way of reducing the contact surface to ensure the press-in effect of the bearing, and avoid the damage of the bearing parts as much as possible.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a bearing press-in mechanism. Background technique [0002] As an important part of fixing and reducing the friction coefficient of load during mechanical rotation, bearing plays an irreplaceable role in the field of mechanical engineering. For example: the two ends of the rotating shaft on the motor rotor need to install bearings to rotate smoothly. In the prior art, some bearing push-in machines are used to complete the bearing press-fit installation, thereby improving the efficiency of mechanical production. However, in the same type of bearing pushing machine, due to the unstable pushing power and the excessive contact surface between the press-in mechanism and the bearing, both the inner ring and the outer ring of the bearing will be affected by the pushing power and cause damage to the bearing. cause economic loss.
