As all can former speed continue to rotate a trip and could stop completely, certain damage can be caused to motor, accelerates the aging of motor,
Need a kind of transmission mechanism for protecting motor.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of power output shafts that can preferably protect motor unidirectionally to pass
Motivation structure.
The technical scheme of the invention to solve the technical problem is: a kind of power output shaft one-way driving mechanism,
Including gear, needle roller seat and power output shaft, the needle roller cover for seat is located on the power output shaft, the geared sleeve
It is located on the needle roller seat, multiple equally distributed mounting grooves is offered on the needle roller seat, are set in the mounting groove
It is equipped with needle roller, the needle roller is located between the inner wall of the gear and the outer wall of the power output shaft, the tooth
Its inner wall is provided with quantity needle roller stroke control block identical with the needle roller, the needle roller stroke control block on wheel
Needle roller stroke control block of the position needle roller corresponding and described with the position of the needle roller corresponding to it in the range of
Movement.
A further preferred embodiment of the present invention are as follows: the needle roller stroke control block includes the tripping concave part of integrally connected
With clamping lug boss, when the gear rotates clockwise, the needle roller is located at the clamping lug boss, described
Needle roller top is located between clamping lug boss and the outer wall of the power output shaft；When the gear rotates counterclockwise
When, the needle roller is located at the tripping concave part, and the needle roller is not contacted with the outer wall of the power output shaft.
A further preferred embodiment of the present invention are as follows: the lower end of the needle roller seat is provided with bearing, the bearing inner sleeve
In in the gear and resisting the needle roller.
A further preferred embodiment of the present invention are as follows: the upper end of the needle roller seat is provided with unilateral bearing.
Compared with the prior art, the advantages of the present invention are as follows when motor is out of service, needle roller on needle roller seat can with it is dynamic
Power output shaft is detached from, and light to motor fret, the service life is longer.

Specific embodiment
The present invention will be described in further detail below with reference to the embodiments of the drawings.
As shown, a kind of power output shaft one-way driving mechanism, including gear 1, needle roller seat 2 and power output shaft 3, rolling
Needle stand 2 is set on power output shaft 3, and gear 1 is set on needle roller seat 2, and multiple equally distributed peaces are offered on needle roller seat 2
Tankage 21 is provided with needle roller 4 in mounting groove 21, and needle roller 4 is located between the inner wall of gear 1 and the outer wall of power output shaft 3, gear
Its inner wall is provided with quantity needle roller stroke control block identical with needle roller 4, the position of needle roller stroke control block and needle roller on 1
It is moved in the range of 4 position is corresponding and needle roller stroke control block of the needle roller 4 corresponding to it, needle roller stroke control block includes
The tripping concave part 51 and clamping lug boss 52 of integrally connected, when gear 1 rotates clockwise, needle roller 4 is located at clamping lug boss
At 52, the top of needle roller 4 is located between clamping lug boss 52 and the outer wall of power output shaft 3；When gear 1 rotates counterclockwise, needle roller 4
At tripping concave part 51, needle roller 4 is not contacted with the outer wall of power output shaft 3, and the lower end of needle roller seat 2 is provided with bearing 6, axis
It holds and is placed in 6 in gear 1 and resists needle roller 4, the upper end of needle roller seat 2 is provided with unilateral bearing 7.
Working principle: when being in original state, the inner wall of gear and the outer wall of power output shaft are not contacted with needle roller, when
When gear rotates clockwise, needle roller top is located between clamping lug boss and the outer wall of power output shaft of gear inner wall at this time, just
Power output shaft can be driven to rotate, when motor stops operating, gear tapers off rotation, effect of the power output shaft in inertia
Lower original speed continues to rotate, and needle roller is back rolled to tripping concave part at this time, and needle roller is not contacted with the outer wall of power output shaft, power
Output shaft tapers off rotation.
A kind of power output shaft one-way driving mechanism provided by the present invention is described in detail above, is answered herein
With a specific example illustrates the principle and implementation of the invention, the explanation of above example is only intended to help to manage
The solution present invention and core concept.It should be pointed out that for those skilled in the art, not departing from original of the invention
