Embodiment
For the ease of the understanding of those skilled in the art, the present invention is made further with reference to embodiment and accompanying drawing
Bright, the content that embodiment refers to not is limitation of the invention.
It is as shown in Figures 1 to 5 the embodiment one of modified reference circle subtractive speed variator, including body 1, input shaft is installed
Set 2, planetary gear set 3, output circle set 4 and the first ring gear 4a, export circle set 4 and be provided with the second ring gear 4b, the planetary gear
Group 3 includes main planetary gear 31, the secondary planetary gear 32 being fixedly and coaxially connected with main planetary gear 31 and for supporting primary planet
The planetary wheel carrier 33 of gear 31 and secondary planetary gear 32, the input axle sleeve 2 are integrally formed with the planetary wheel carrier 33, primary planet tooth
Wheel 31 is connected by meshing transmission with the first ring gear 4a, and secondary planetary gear 32 is connected by meshing transmission with the second ring gear 4b, in first
Gear ring 4a reference diameter is more than or less than the second ring gear 4b reference diameter；The installation body 1 is equiped with and pacified
The inwall of the gear ring installation lid 6 that the dress pairing of body 1 is fixedly connected, gear ring installation lid 6 and output circle set 4 offers spline
7, the first ring gear 4a and the second ring gear 4b are provided with spline tooth 8 corresponding with spline 7, the first ring gear 4a's
Spline tooth 8 is embedded in the spline 7 of gear ring installation lid 6, the spline 7 of the second ring gear 4b insertion output circle of spline tooth 8 set 4
It is interior.
During the deceleration transmission of modified reference circle subtractive speed variator, the main shaft of motor is passed by input axle sleeve 2
Planetary wheel carrier 33 is handed to, and drives main planetary gear 31 and secondary planetary gear 32 to do synchronous circular motion, and respectively passes moment of torsion
Be handed to the first ring gear 4a and the second ring gear 4b, due to the first ring gear 4a with installation body 1 be fixedly connected, the first ring gear
4a can not be rotated, and the moment of torsion of motor output is all transferred to the second ring gear 4b, and is exported torque by output circle set 4,
It is achieved thereby that modified reference circle subtractive speed variator deceleration transmission function.
