Abstract

The utility model discloses a motor non-return mechanism, which comprises a rotor output gear, a ratchet wheel, a non-return gear and a non-return claw; the ratchet wheel is fixed on a rotor output gear; the non-return gear is engaged with the rotor output gear; the non-return claw is arranged on the non-return gear; and the non-return claw is in interference with the ratchet wheel when the motor reversely rotates. The motor non-return mechanism can compel the motor to be started towards the same direction at a time by arranging the ratchet wheel and the non-return claw which can be in interference when the motor reversely rotates, and is simple in structure and low in machining process.

Description

The non-return mechanism of a kind of motor

Technical field

The utility model relates to the non-return mechanism of a kind of motor.

Background technology

Synchronous machine is when starting, and the turning to of motor is not to fix, therefore is not suitable for being used in the timer of some household electrical appliance (like washing machine and microwave oven).In order to overcome this shortcoming, a non-return mechanism need be set, identical to guarantee the each direction that starts of synchronous machine.

The utility model content

The utility model technical problem to be solved provides a kind of simple in structure, can force the each non-return mechanism that all starts in the same direction of motor.

In order to solve the problems of the technologies described above, the technical scheme that the utility model provided is: the non-return mechanism of a kind of motor comprises rotor output gear, ratchet, non-return gear and non-return claw; Said ratchet is fixed on the rotor output gear; Said non-return gear and the engagement of rotor output gear; Said non-return claw is arranged on the non-return gear; Said non-return claw when the motor counter-rotating and ratchet interfere.

The edge of said ratchet is provided with serrated slot; One end of said non-return claw is connected with non-return gear elasticity, and the other end stretches in the serrated slot of ratchet; Said non-return claw props up the serrated slot of ratchet when the motor counter-rotating.

After having adopted technique scheme; The utlity model has following beneficial effect: the utility model is through being provided with the ratchet and the non-return claw that can interfere when the motor counter-rotating; Force motor all to start in the same direction, simple in structure, processing cost is low at every turn.

Description of drawings

For the content that makes the utility model is expressly understood more easily,, the utility model is done further detailed explanation, wherein below according to specific embodiment and combine accompanying drawing

The structural representation of the utility model when Fig. 1 is rotated in the forward for motor.

The structural representation of the utility model when Fig. 2 is the motor counter-rotating.

Label in the accompanying drawing is:

Output gear 1, ratchet 2, serrated slot 21, non-return gear 3, non-return claw 4.

Embodiment

(embodiment 1)

The non-return mechanism of the motor of present embodiment comprises rotor output gear 1, ratchet 2, non-return gear 3 and non-return claw 4.

Ratchet 2 is fixed on the rotor output gear 1.

Non-return gear

3 and 1 engagement of rotor output gear.Non-return claw 4 is arranged on the non-return gear 3.The edge of ratchet 2 is provided with serrated slot 21.One end of non-return claw 4 is connected with non-return gear 3 elasticity, and the other end stretches in the serrated slot 21 of ratchet 2.

See Fig. 1, when motor was rotated in the forward, non-return claw 4 was followed non-return gear 3 and is rotated, and motor normally rotates.

See Fig. 2, when the motor counter-rotating, non-return claw 4 is followed non-return gear 3 and is rotated, and non-return claw 4 interferes with the serrated slot 21 of ratchet 2, and this moment, non-return claw 4 propped up the serrated slot 21 of ratchet 2, resisted ratchet 2 rotations, thereby forced the motor commutation rotation.

Above-described specific embodiment; Purpose, technical scheme and beneficial effect to the utility model have carried out further explain, it should be understood that the above is merely the specific embodiment of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection range of the utility model.
