Son 111 and the driven rotor 121 being sheathed on output shaft 120, are provided between the power rotor 111 and driven rotor 121
The active cone pulley 112 and driven cone pulley 122 being oppositely arranged, the active cone pulley 112 are arranged on input shaft 110, driven cone pulley
122 are arranged on output shaft 120, and ball 20, the initiative taper are provided between the active cone pulley 112 and driven cone pulley 122
Compression spring 140 is provided between wheel and power rotor, the compression spring two ends are resisted against active cone pulley and actively turned respectively
Son is to ensure that ball is sandwiched between active cone pulley and driven cone pulley;It is located in the housing 10 between power rotor and driven rotor
With shading ring 130.Bearing, the output shaft and shell are provided between the input shaft and housing, power rotor, active cone pulley
Body, driven rotor, driven cone pulley are provided with bearing.In the present embodiment, power rotor is provided with the bullet for placement force spring
Spring groove.
Ball 20 described in the present embodiment is provided with 4, periphery and power rotor 111 and the driven rotor 121 of ball 20
It is in contact;The ball is evenly distributed in the circumferential direction, and is provided with live roller 30, the transmission between adjacent ball 20
Roller 30 is in contact with ball 20, and each live roller 30 is axially fixed on a worm gear 40, the turbine 40 and live roller
30 are sandwiched between active cone pulley 112 and driven cone pulley 122 and active cone pulley and driven cone pulley forward surface have for roller and snail
The groove of wheel;The middle part of the input shaft is through there is a drive rod 50, and active cone pulley is run through and driven in the end of drive rod 50
Cone pulley and end are provided with the worm screw 510 with worm gear 40 to cooperation.
During work, power rotor 111 and driven rotor 121 press tightly against ball under the promotion of compression spring 140
20, and them is fitted close respectively with four live rollers 30.When power rotor 111 is rotated under the drive of input shaft 110,
It will drive four balls 20 to do corresponding rotation respectively, and rotation is passed into driven biography 121;Meanwhile, four balls 20
Also live roller 30 is driven to rotate respectively.It is relative due in the presence of spring pressure 30, being done between ball 20 and live roller 30
