Abstract
The utility model discloses a sub-driven electric gourd, which comprises an electric gourd, wherein a motor of the electric gourd and a speed reducer are arranged at the same end of a drum, a motor shaft is connected with the speed reducer shaft I through a coupler, the other end of the speed reducer shaft I is positioned in the hollow shaft of the drum, the other end of the drum is rotatively arranged on a cylinder cover, a gear on the speed reducer shaft II is engaged on the gear of the hollow shaft. The utility model saves a master driving shaft and a coupler and directly uses the motor to anchor the speed reducer through the above modification, which causes driving torque big, improves lifting height and operation stability, reduces noise and lengthens use time.
Description
Technical field:
The utility model relates to hoisting crane, the rear drive electric block that particularly a kind of lifting altitude height, running are steadily, noise is little, the life-span is long.
Background technology:
Existing electric block, its structure is that two ends are separately installed with motor and retarder on a frame, be connected with a reel by two coupler in the frame between motor and retarder, in-line is fixed with protective cover on the frame in motor, reel and the retarder outside, one of retarder is connected on the motor shaft by the main driving axle in the reel hollow shaft, and the meshed transmission gear on gear and the reel hollow shaft is arranged on two of retarder.This structure because motor and retarder are installed in the two ends of reel respectively, causes main driving axle oversize, and it is excessive to cause driving amount of deflection, not only restricted hoisting force and height, and noise is big, and the life-span is short.
Summary of the invention:
The purpose of this utility model provides a kind of lifting altitude height, operates steadily, and noise is little, the rear drive electric block that the life-span is long.
The technical solution of the utility model is finished as follows, it comprises an electric block, it is characterized in that: the motor of this electric block and retarder are installed in the same end of reel, motor shaft is connected by one of coupler and retarder, the other end that retarder is one is rotatably installed in the hollow shaft of reel, the other end of reel is rotatably installed on the tube cover, and the gear mesh on two of the retarders is on the gear of hollow shaft.The utility model has saved main driving axle and a coupler through above-mentioned improvement, directly uses the driven by motor retarder, makes the driving torque big, has improved lifting altitude and degree of operating steadily, and noise is little, long service life.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
The utility model is equipped with reel cover 3 and coupling guard 5 at the two ends of reduction-gear housing 4 in-line, the output shaft of motor 6 is connected and fixed with one 8 of the retarder in a coupler 7 and the reduction-gear housing in coupling guard, like this retarder and motor is installed in the same end of reel 2.Other end of retarder is rotatably connected in the hollow shaft 9 of reel, has the gear on two of gear and the retarders to be meshed on the hollow shaft, drives spool and rotates.There is the axle normal-running fit on bearing 1 and the reel cover at the other end center of spool.During work, rotation of driven by motor retarder, through being rotated by the hollow shaft on the gear driven reel on two of the retarders after the variable gear speed change, reel drives the steel cable that is coiled on the reel and hoists with suspension hook, convey materials, owing to saved main driving axle, motor shaft directly drives one of retarder, drives reel work nearby with two of retarders, shortened torque greatly, improved lifting altitude and stationarity, it is little to make it have a noise, the advantage that the life-span is long.
