Lower-lever transmission device of double-lever vacuum extruder

Abstract

The invention relates to a lower-stage transmission device of a double-stage vacuum extruder, which comprises an electric motor 1. A power output shaft of the electric motor 1 is provided with a steel ball coupling 2 which is provided with a belt 3, the other end of the belt 3 is sleeved on a large belt pulley 4 which is connected with an input shaft 8 at the power input end of a planetary decelerator 5, a flange 7 of the planetary decelerator 5 is directly connected with a receiving box 6, and an output shaft 9 of the planetary decelerator 5 is connected with an extruding shaft 10 inside thereceiving box 6 together through a spline. During working, the electric motor 1 drives the steel ball coupling 2, then the steel ball coupling 2 drives the lower-stage large belt pulley 4 to rotate through the belt 3, the large belt pulley 4 drives the input shaft 8 of the planetary decelerator 5 to rotate, and the output shaft 9 of the planetary decelerator 5 is rotated by the driving of each-stage driving deceleration of the planetary decelerator 5 so as to drive the extruding shaft 10 to rotate. The lower-stage transmission device has the characteristics of compact structure, high mechanical efficiency, and convenient maintenance and operation.

Description

technical field [0001] The invention relates to a transmission device in the field of brick and tile machinery, in particular to a lower-stage transmission device of a two-stage vacuum extruder. Background technique [0002] In the existing domestic two-stage vacuum extruder, the power of the lower extrusion part is transmitted to the extrusion shaft by the motor, belt, pneumatic clutch, and planetary reducer. When the extruder stops, disengage the pneumatic clutch, that is, the motor does not stop, and the extrusion shaft stops by stopping the reducer. This will easily lead to heavy-duty parking and overloaded starting, which will have a very adverse effect on the transmission system. At the same time, the extrusion shaft will deform and torsional vibration due to excessive instantaneous torque; and the existing lower-level transmission methods mostly use the following two types: 1. A fulcrum bearing seat is set between the reducer and the receiving box; 2. The reducer and ...
