Axial locating device for jumbolter motor

Abstract

The invention discloses an axial locating device for a jumbolter motor. A right end shaft of a motor gear is additionally provided with a threaded hole or a threaded rod and fixed by a pressing plate, a spring washer and a screw or nut. The axial locating device has the advantages that the axial locating device for the jumbolter motor is connected into a fixed assembly through the pressing plate, the spring washer and the screw or nut; before the assembly is assembled with a motor shell, the gap is adjusted through an adjusting pad, and therefore friction between the motor gear and a bearing pedestal can be avoided, and the gap between the motor gear and the inner end surface of the motor shell can be guaranteed through a measuring tool after assembly. The motor gear is located at an ideal position inside the motor shell under the axial resistance of a bearing. When the motor works, the two end surfaces of the motor gear do not rub against the inner end surface of the motor shell or the inner end surface of the bearing pedestal to emit heat, and therefore the phenomenon that the bearing is damaged due to heat emission is avoided, and the service life of the jumbolter motor is prolonged.

Description

technical field [0001] The invention relates to a rock bolter motor. Background technique [0002] The right end shaft of the motor gear of the bolter motor is installed in the bearing, the bearing is installed in the bearing seat, and an adjustment pad is also installed between the motor gear and the bearing. The adjustment pad is higher than the bearing seat. Its function is that when the motor gear rotates, its end face does not rub against the end face of the bearing seat. The left end shaft of the motor gear penetrates the through hole in the motor housing, and the bearing is installed on the left end shaft of the motor gear and the motor from the left end. In the bearing hole of the housing, snap rings on both ends of the motor gear, press the paper pad and the bottom plate on the motor housing with screws in turn. The ideal position of the motor gear installed in the motor housing is that there is a gap of 0.03-0.05 around, so that the motor can run efficiently witho...

AI Technical Summary

Problems solved by technology

The ideal position of the motor gear installed in the motor housing is that there is a gap of 0.03-0.05 around, so that the motor can run efficiently without friction. Since the motor gear has no axial positioning device, the snap ring is affected by the assembly gap and the adjustment pad. Affected by thickness changes, it cannot play the role of axial positioning

Once the motor gear shaft and the bearing or the bearing and the bearing hole are loosened, the motor gear will move axially in the motor housing, which will cause friction and heat generation between the end face of the motor gear and the inner end face of the motor housing or the inner end face of the bearing seat and damage the bearing.
