[background technique]
Known, the free wheel device of conventional two retainer structure, it generally comprises interior retainer, outer retainer, voussoir, wavy spring band and damping card, interior retainer, outer retainer, wavy spring band and damping cartoon often adopt metal stamping to be shaped, this structure free wheel device comprises design of part complexity, quantity is many, the effect of wavy spring band in this structure free wheel device applies spring force to voussoir, but at high speeds, the elastic force of spring needed for voussoir is the function of velocity squared, and wavy spring band elasticity is less, and overall elastic force skewness weighing apparatus, clutch engagement can be caused to throw off unreliable, therefore, the free wheel device of two retainer structure is not suitable for the use at high-speed working condition.
[summary of the invention]
In order to overcome the deficiency in background technique, the invention discloses a kind of high speed free wheel device of single retainer structure, by the independently spring sheet 3 of the outer installment at each voussoir 2, spring sheet 3 can apply spring force to voussoir 2 respectively, to achieve in the process of running up not only overall elastic force to be evenly distributed, elastic force is large, and better adapts to the object of centrifugal forces affect suffered by voussoir 2 at high speeds.
For achieving the above object, the present invention adopts following technological scheme:
A kind of high speed free wheel device of single retainer structure, comprise retainer, voussoir and spring sheet, at the circumferentially interval of retainer, multiple fenestra is set uniformly, described voussoir is separately positioned in fenestra, spring sheet is equipped with in the outside of voussoir, the external diameter of described retainer bi-side is double polarizing keys sprocket-type structure, the external diameter of retainer is interval with multiple boss exceeding retainer external diameter, downward holding sheet is provided with in the both sides of spring sheet plane, described holding sheet is circular shape, is provided with the support plate of extension in the bottom of holding sheet.
The high speed free wheel device of described single retainer structure, the external diameter of described retainer and outer raceway are interference fit.
The high speed free wheel device of described single retainer structure, the holding sheet of described spring sheet is connected on the lintel of retainer fenestra, and the support plate of described spring sheet is arranged on the bottom of voussoir bi-side.
The high speed free wheel device of described single retainer structure, described retainer material is engineering plastics.
Owing to have employed technique scheme, the present invention has following superiority:
1, by the outer installment independently spring sheet 3 at each voussoir 2, spring sheet 3 can apply spring force to voussoir 2 respectively, in the process of running up, not only overall elastic force is evenly distributed, elastic force is large, voussoir 2 centrifugal force larger at a high speed can also be adapted to, and the support plate 6 of spring sheet 3 bottom is arranged on the bottom of voussoir 2 bi-side, can be used for applying the elastic force of voussoir 3 when engaging and voussoir 3 from surmount engage time required reposition force, when the present invention is used under high-speed working condition engagement and disengagement more reliable.
2, the both sides external diameter of retainer 1 is set to double polarizing keys sprocket-type structure, and with outer raceway interference fit,
In the fenestra 8 of retainer 1, voussoir 2 is installed, in the process of running up, make retainer 1 and voussoir 2 be rubbing contact with outer raceway all the time, overcome the inertial force of retainer 1 and voussoir 2 when the rapid acceleration, deceleration of clutch, to ensure the engagement of clutch and to throw off rapider, and reduce wear.
The material of 3, described retainer 1 is engineering plastics molding and forming, and centrifugal force is less, and shock-resistant.
