Abstract
The utility model discloses an electric block without a second nodal shaft, which belongs to a crane. The utility model solves the technical problem of the height of a weight lifted by one electric block without a second nodal shaft is large, and a transmission shaft can not generate deflection. The electric block without a second nodal shaft comprises a motor, a speed reducer and a reel drum, wherein the motor and the speed reducer are on the same side of the reel drum; a shaft coupling arranged between the motor and the speed reducer is respectively connected with a motor shaft and an input shaft of the speed reducer. The utility model is especially suitable for the crane with large height of the lifted weight.
Description
Technical field
The utility model relates to a kind of hoisting crane, particularly a kind of nothing two nodal axisn electric blocks.
Background technology
The transmission device of existing electric block is that motor is connected with the reducer shaft of the reel other end by two nodal axisns that are through in the reel, this electric block is for the big occasion of some lift heavy object height degree, the length that need add long carriage, but when reel length rose to certain value, two nodal axisns in it will produce the amount of deflection problem.
Summary of the invention
The utility model technical issues that need to address provide a kind of nothing two nodal axisn electric blocks, can the higher weight of sling height and the transmission shaft of electric block can not produce the amount of deflection problem.The technical solution of the utility model is, a kind of nothing two nodal axisn electric blocks, it comprises electrical motor, retarder and reel, it is characterized in that: electrical motor and retarder are provided with coupler and are connected with reducer input shaft with motor reel respectively in the same side of reel between electrical motor and retarder.The utility model is owing to place retarder and motor the same side of reel, motor is connected with reducer shaft by coupler, do not have two nodal axisns in the reel, thus the utility model to have the hoisting heavy height compared with the prior art big and transmission shaft can not produce the advantage of amount of deflection problem.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
In conjunction with above-mentioned accompanying drawing the utility model is elaborated, retarder 3 and electrical motor 1 are set, be provided with coupler 2 between electrical motor 1 and the retarder 3 and be connected with reducer input shaft with motor reel respectively in a side of electric gourd drum 4.Thereby this electric block do not have two nodal axisns in the reel, and the length of reel can determine according to the height of hoisting crane lifted weight, and is not subjected to two nodal axisns to increase the restriction that produces amount of deflection.This electric block is made especially in the big hoisting crane of sling height.
