In ceramic processing industry, stirrer is common equipment, is subject to the processing technology of pottery, and the speed reducer that requires to drive stirrer has the characteristic that input power is little, output torque is large, and requires the continuous normal operation of twenty four hours in a day.
Present stage, cycloidal planetary gear speed reducer commonly used or worm and worm gear speed reducer in the whipping process of pottery processing, the former complex structure, maintenance difficult and cost are higher, and the latter's efficient is lower, can not satisfy the requirement of ceramic large-scale mass production.
The model utility content
For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of twin-stage gear reduction unit, and it is simple in structure, convenient for maintaining, cost is lower and have higher efficient.
For achieving the above object, the utility model adopts following technological scheme:
The twin-stage gear reduction unit, comprise the first casing, the second casing, input shaft, output shaft, the first transmission shaft, second driving shaft, the first casing is fixedly connected with the second casing, input shaft is articulated in the first casing, one end of the first transmission shaft is articulated in the first casing, the other end cross-under is in the second casing, and be connected with synchronously on the first transmission shaft one with the first input gear of input shaft engagement, second driving shaft is articulated in the second casing, and be connected with synchronously the second input gear of the one and first transmission shaft engagement on the second driving shaft, output shaft is articulated in the second casing, be connected with synchronously on the output shaft one with the second output gear of second driving shaft engagement.
Be positioned at the first output gear that is connected with synchronously the engagement of the one and second input gear on the part of the second casing on the first transmission shaft.
The end that the first transmission shaft is positioned at the second casing is fixed with a lock washer for backstop the first output gear.
Be provided with an axle sleeve between the first casing and the second casing, this axle sleeve is socketed on the first transmission shaft and its two ends are fixed with the first casing and the second casing respectively.
The inboard of axle sleeve also is provided with an oil sealing that is enclosed within on the first transmission shaft.
The beneficial effects of the utility model are:
