The utility model is characterized in that a spline with an internal spiral is arranged on the inner wall of the driving shell (5), the driving shell is matched with a gear which is arranged on the outer circumference of the friction copper sheet (7) through the spline with an internal spiral (14), the outer wall of the driving shell (5) is provided with a gear, the driving shell is matched with a gear of a power output shaft of the driving motor through the gear (15) which is arranged on the outer wall of the driving shell (5), and the power transmission of the motor can be realized. Because the utility model can realize that a high-power low-speed motor can be replaced by a corresponding small-size high-speed motor, the whole volume of a starter can be reduced, the operation of the starter is stable, the cost can be correspondingly reduced and the utility model has a good development prospect.
Description
Technical field
The utility model belongs to the starter motor field of motor, refers more particularly to a kind of deceleration the friction type overrunning clutch.
Background technique
The friction type one-way element is usually used in the start-up course of starter motor of high power engine.The feature of this one-way element is that power is directly to be carried on the wearing piece of one-way element by armature shaft, realizes the process of motor driving transmission of power to the engagement starting gear, and its advantage is simple in structure.But because the structure characteristic that direct driving force is transmitted, when having determined the one-way element use of this structure, can only select for use the powerful motor of the slow-speed of revolution as actuating motor, thereby cause single clutch long-pending excessive, limit its use on high rotating speed slowdown type starter to body.
The model utility content
The purpose of this utility model is to provide a kind of high-speed electric expreess locomotive with relative smaller size smaller to substitute the high-power low-speed motor, to reduce the starter motor volume, improve the starter motor working efficiency, increase the service life, alleviate complete machine weight, reduce production costs, improve the initial stage frictional resistance between friction copper sheet and the friction steel disc simultaneously, prevent the overrunning clutch that wearing piece skids.
The utility model is realized by following manner: a kind of external gear deceleration friction chip overrunning clutch, by actuation gear, ratch, the driving gear axle, the friction copper sheet, the friction steel disc, drive shell, movable sheath, locating stud, removable insole pieces, drive motor constitutes, on the driving gear axle with the friction steel disc the spiral spline in corresponding part, the inner circumference of friction steel disc is the helical spline fitted on gear shape and the driving gear axle, actuation gear is fixed in an end of driving gear axle by ratch, the excircle of friction copper sheet is gear shape, by movable sheath will rub copper sheet with the friction steel disc be buckled into one, be loaded on the driving gear axle, its outer end one of suit again drives shell, establish spline on the inwall of driving shell, by the excircle gear matched of spline with the friction copper sheet, the outer wall that drives shell is established gear, by the gear on the driving outer shell outer wall and the armature shaft gear matched of drive motor, realize the motor power transmission.
In order to reduce the noise of outer wall gear during that drives shell, the be processed into helical tooth that the driving outer shell outer wall cogs with the generator shaft gear transmission.
Also be provided with buffer stopper with the removable insole pieces corresponding part on the driving gear axle, in by driving shell and end cap it being wrapped in.
The end that ratch cooperates with actuation gear is a quill shaft, and hollow wall is provided with the key pin groove, and gear shaft cooperates with ratch by key pin, and the quill shaft of ratch is provided with coil tension spring, withstands on the termination of gear shaft.
Its working principle is: during starting, after the fork of starter motor advances big flywheel with actuation gear, the actuating motor circuit is connected, the rotation torque of motor is passed to friction copper sheet group by driving shell, by the effect of helical spline, make the reach of friction copper sheet, produce bigger frictional resistance with the friction steel disc, rotation torque combines with the friction of friction steel disc by the friction copper sheet and is passed to the driving gear axle, finally pilots engine by actuation gear.And after engine start, the rotating speed of driving gear axle is greater than the rotating speed that actuating motor transmitted, under the effect of helical spline, thrust after forming one, the friction steel disc separates with the friction copper sheet, makes the power of starter motor and driving gear axle get in touch cut-out, and the drive engaging gear breaks away from big flywheel.
Because the utility model has been realized under the prerequisite that does not reduce the starter output torque, by gear reduction, improve the motor output torque, with the alternative high-power low-speed motor of the high-speed electric expreess locomotive of relative smaller size smaller, starter motor volume integral body is dwindled greatly, and the also corresponding decline of cost.In addition, by internal thread spline being set at the driving outer casing inner wall, make overrunning clutch when work under the effect of internal thread spline, the power that pushes away before on the friction copper sheet, producing one, guaranteed the frictional resistance between friction copper sheet and the friction steel disc, prevent skidding of overrunning clutch, therefore the utlity model has good DEVELOPMENT PROSPECT.
