Abstract

A double-driving speed reducing motor comprises a reduction box and two motors. An output shaft which extends out of the box is disposed on a third wheel in the reduction box, two symmetrically meshed third shaft teeth are arranged on two sides of the backward lower side of the third wheel, two second wheels are respectively backwardly connected onto two third shafts, two symmetrically mounted second shaft teeth are respectively meshed on the two second wheels, two first wheels are mounted at rear edges of the two second shafts, a motor shaft tooth is meshed on the outer side of each first wheel, a motor shaft is mounted in a shaft hole of each motor shaft tooth and penetrates through a box body via a bearing block to be connected onto one tertiary motor, and the motors are respectively fixed onto outer walls of a box cover of the reduction box via bolts. The two tertiary motors jointly drive a speed reducer to drive an electric hoist and double outputted rotation torque, and the double-driving speed reducing motor has the advantages of simple structure, easiness in manufacture and convenience in maintenance.

Description

Two driving reducing motors

Technical field:

The utility model belongs to motor, particularly a kind of two reducing motors that drive of installing on 10 tons of electric blocks that are applicable to.

Background technology:

At present, the reducing motor of driving electric block all is to combine with a motor and a decelerator.Increase the output rotating torque if desired, also need to increase again set of gears group and casing thereof.Not only drive mechanism complexity, and volume is big, and parts are many, brings a lot of inconvenience for manufacturing and maintenance.

Summary of the invention:

The purpose of this utility model provides and a kind ofly exports that rotating torque is big, volume is little, simple in structure, manufacturing and two reducing motors that drive easy to maintenance.

The technical solution of the utility model is finished as follows, it includes a reduction box and two motors, it is characterized in that: outside case, be extended with an output shaft on the three-wheel in reduction box, on three-wheel, be engaged with two three axle teeth to back lower place bilateral symmetry, being connected with one two respectively backward on two three takes turns, take turns two axle teeth that are engaged with a symmetry installation respectively at two two, installing one one in the back respectively on each two takes turns, each one is taken turns the outside and is engaged with a motor shaft tooth respectively, be separately installed with a motor shaft in the axis hole of each motor shaft tooth, each motor shaft passes casing through bearing pedestal respectively and is connected on the three-grade electric machine, and each motor is fixed by bolts to respectively on the case lid outer wall of reduction box.

The utility model drives a reductor and removes to drive electric block with two three-grade electric machines are common, the rotating torque of output is increased be twice, and has advantage simple in structure, easy to manufacture, easy to maintenance.

Description of drawings:

Fig. 1 is vertical sectional structure schematic diagram of the present utility model,

Fig. 2 is a drive connection schematic diagram of the present utility model.

Embodiment:

Further describe embodiment in conjunction with above accompanying drawing, the utility model is to be extended with an output shaft 7 on the three-wheel 6 in a reduction box 8 outside case, on three-wheel, be engaged with two three axle teeth 5 and 5 ' to back lower place bilateral symmetry, be connected with one two respectively backward on two three and take turns 4 and 4 ', take turns two axle teeth 3 and 3 ' that are engaged with a symmetry installation respectively at two two, install one one respectively on each two and take turns 2 and 2 ', each one is taken turns the outside and is engaged with a motor shaft tooth 1 and 1 ' respectively, be separately installed with a motor shaft in each motor shaft tooth centre bore, each motor shaft passes casing through bearing pedestal respectively and is connected on a three-grade electric machine 10 and 10 ', and each motor is fixed by bolts to respectively on the case lid 9 of reduction box.The utility model with two three-grade electric machines by the two-way transmission, drive speed reducer output shaft and rotate, more change under the situation of reduction box not having, the driving torque of output is multiplied, be particularly suitable on 10 tons of electric blocks, using.

Claims

1. two driving reducing motors, it includes a reduction box and two motors, it is characterized in that: outside case, be extended with an output shaft on the three-wheel in reduction box, on three-wheel, be engaged with two three axle teeth to back lower place bilateral symmetry, being connected with one two respectively backward on two three takes turns, take turns two axle teeth that are engaged with a symmetry installation respectively at two two, installing one one in the back respectively on each two takes turns, each one is taken turns the outside and is engaged with a motor shaft tooth respectively, be separately installed with a motor shaft in the axis hole of each motor shaft tooth, each motor shaft passes casing through bearing pedestal respectively and is connected on the three-grade electric machine, and each motor is fixed by bolts to respectively on the case lid outer wall of reduction box.
