Problems solved by technology

The cycloid reducer mostly adopts the cantilever structure of the pin shaft, and the two planetary wheels bear uneven loads, which increases the friction loss of the pin sleeve and reduces the efficiency of the reducer; and the manufacturing precision is high, and special machine tools are required for processing, and the equipment investment is relatively high. Larger and more expensive to manufacture
Applied in long-term high-load operation equipment, the service life is greatly reduced and the cost of the whole set is relatively high

Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with specific embodiments.

[0015] Such as figure 1 As shown, the reducer of the mixer hoist includes: brake motor 1, input shaft 3, eccentric sleeve 9, left arm 4, right arm 10, pin shaft 6, planetary wheel 8, rope wheel (internal gear) 7 , Pin sleeve 5. The brake motor 1 is connected to the input shaft 3 through a spline shaft to transmit power, and an eccentric sleeve 9 with a displacement of 180 degrees is installed on the input shaft 3. δ( figure 2 The shown δ is 4.5mm), the size of δ is equal to the center distance a between the rope wheel (internal gear) 7 and the planetary wheel 8 meshing, that is: δ=a], two symmetrical ball bearings are installed on the eccentric sleeve 9, and the two The two planetary wheels 8 are mounted symmetrically on the outer rings of the two ball bearings to form an H mechanism (eccentric mechanism). The power drives the H mechanism to rotate through the input ...

Abstract

The invention discloses a reducer of an elevator special for stirrers. The reducer comprises a brake motor (1), an input shaft (3), an eccentric sleeve (9), a left turn arm (4), a right turn arm (10), a pin (6), planet gears (8), a sheave (7) and a pin sleeve (5). Balanced transmission by inner and outer gears is applied, a hole-pin output mechanism is applied, the pin is in a double support structure, and accordingly the reducer is compact in structure. The reducer is large in speed ratio, available for stable transmission at high speed, and low in noise and is also available for transmission of large power and large torque, resistant to overload and energy-saving and 30% lower in cost.

Description

technical field [0001] In particular, the present invention relates to a speed reducer for a special hoist for a mixer. Background technique [0002] At present, the commonly used elevators for mixers mostly use the extension of the output shaft of the reducer to connect the sheave, and the other end is supported by a cantilever or a bracket. The reducer mostly adopts cylindrical gear transmission reducer or cycloid reducer. The cycloid reducer mostly adopts the cantilever structure of the pin shaft, and the two planetary wheels bear uneven loads, which increases the friction loss of the pin sleeve and reduces the efficiency of the reducer; and the manufacturing precision is high, and special machine tools are required for processing, and the equipment investment is relatively high. Larger and more expensive to manufacture. When used in equipment that operates under heavy load for a long time, the service life is greatly reduced and the cost of the whole set is relatively ...
