Abstract

The utility model relates to a starting engine for an electric motor, which relates to an improved structure of a starting engine for an electric motor. The utility model provides a starting engine for an electric motor, which can adjust the reduction ratio of the starting engine and save energy sources. The utility model comprises an electric motor. A planetary gear set is arranged in the case body outside the principal axis of the electric motor. The utility model has the structural proposal that the planetary gear set is connected with an output shaft through a clutch.

Description

A kind of motor starter

Technical field:

The utility model relates to the improvement of motor starter structure.

Background technology:

At present, contain the motor starter of planetary gear speed reducing mechanism, have only a kind of fixed torque output usually; And can not adjust speed reducing ratio according to different operating modes, therefore caused the waste of the energy.

The utility model content:

The utility model is exactly at the problems referred to above, and a kind of motor starter of adjusting starter motor speed reducing ratio, energy savings is provided.

The utility model adopts following technical scheme, and the utility model comprises motor, is planetary gearsets in the casing outside the main shaft of motor, and its structural feature planetary gearsets links to each other with output shaft by clutch.

The beneficial effects of the utility model:

1, energy-conservation:

Because planetary gearsets of the present utility model links to each other with output shaft by clutch, just can be as required, or a kind of speed after the employing planetary gearsets speed change, or directly adopt motor speed, energy savings effectively;

2, make simply:

The utility model is on the basis that keeps existing structure, only increases clutch between planetary gearsets and output shaft; Therefore, make easily, be easy to popularize.

Embodiment:

The utility model comprises motor 1, is planetary gearsets 5 in the casing 2 outside the main shaft 4 of motor 1, and planetary gearsets 5 links to each other with output shaft 20 by clutch 11.

Clutch 11 can adopt following structure, clutch 11 comprises the end cap 18 of the sky cover on the output shaft 20, bolt 17 on the end cap 18 links to each other with driving center 16, planet tooth 7 outer ring gears 8, and ring gear 8 has with the side between the gear bush 9 of jaw clutch 32 and is copper sheathing 14; The side of the positioning sleeve 12 that ring gear 8 is outer is provided with the pushing ring 10 that the jacking block 13 with 2 15 upper springs 31 of casing links to each other, and the side of pushing ring 10 has groove 30; The joystick 19 of casing 2 links to each other with connecting rod 25, pivoted loop 26 by the axle 24 on the casing 2, and the axle 28 of the two ends pawl 23 of the dog collar 27 on 2 22 of the casings contacts with pivoted loop 26 outer slideways 29; Left side side on pivoted loop 26, the dog collar 27 is respectively arranged with pushing ring 10 corresponding push rods 3.

Output shaft 20 is outside equipped with belt pulley 21.

Below in conjunction with a description of drawings course of action of the present utility model:

When the utility model starter motor was used to start: joystick 19 rotated, connecting rod 25 drives pivoted loop 26 and rotates around axle 24, push rod 3 on pivoted loop 26, the dog collar 27 moves along the side plane of pushing ring 10, making positioning sleeve 12 drive driving center 16 moves to left (meanwhile along copper sheathing 14, the rotation of pivoted loop 26 makes pawl 23 be meshed with the fluted disc 6 of planetary gearsets 5).The jaw clutch 32 of the left side of gear bush 9 is left in driving center 16 right sides, and at this moment, motor 1 drives output shaft 20 low-speed runnings by planetary gearsets 5.

When the utility model starter motor normally used: joystick 19 rotated, and connecting rod 25 drives pivoted loop 26 and rotates around axle 24, and the push rod 3 on pivoted loop 26, the dog collar 27 falls within the groove 30 of pushing ring 10; Spring 31 promotes positioning sleeves 12 makes driving center 16 along copper sheathing 14 move to right (meanwhile, the rotation of pivoted loop 26 makes pawl 23 leave the fluted disc 6 of planetary gearsets 5).The right side of driving center 16 links to each other with gear bush 9 jaw clutches 32, at this moment, and the connection that planetary gearsets 5 breaks away from output shaft 20, and motor 1 runs up by the gear bush 9 direct output shafts 20 that drive.
