Problems solved by technology

When the speed changer is connected to the motor, the drive wheel is positioned by the output shaft of the motor, and the power is transmitted by the flat key. Its disadvantages are: the fit between the shaft and the hole is a tight transition fit or interference fit when the flat key is used to connect. The gap is small, but there are the following errors due to processing and assembly accuracy and other reasons: 1. The axis of the driving wheel positioned by the planetary cone is offset from the design axis, resulting in a coaxiality error; 2. The active wheel positioned by the planetary cone There is a verticality error between the axis of the wheel and the radial direction of the planetary cone; 3. There is a coaxiality error between the motor output shaft and the connecting flange; 4. There is a verticality error between the motor output shaft and the connecting flange; 5. There is a coaxiality error between the motor output shaft and the transmission drive wheel when the motor is assembled with the transmission; 6. There is a parallelism error between the centerline of the motor output shaft and the centerline of the transmission drive wheel when the motor is assembled with the transmission
The combined effect of these errors makes the driving wheel not only be affected by the circumferential force during normal operation, but also the driving wheel is affected by the radial force due to the coaxiality error, and the driving wheel is subjected to the bending moment in the axial direction due to the verticality error, and the driving wheel The radial force on the wheel causes it to deviate from the centering position of the planetary cone, causing the planetary cone to be stressed unevenly, and individual planetary cones to slip, and the bending moment on the driving wheel in the axial direction is transmitted to the planetary cone The disk is subjected to alternating torque during operation, which causes loud noise, accelerated wear, and even damage, which seriously endangers the normal operation of the equipment.

Abstract

The invention relates to a spline direct-connected planetary conical disc type stepless reducer which is characterized in that the driving wheels thereof and the output shaft of a motor are in larger-gap splined connection so that the splines only transmit the torque and can be adapted to the installing and manufacturing error of the driving wheels and the output shaft of the motor. The spline direct-connected planetary conical disc type stepless reducer has the advantages of low installing and manufacturing precision requirement, strong bearing capacity, low noise and long service life.

Description

technical field [0001] The invention relates to a spline connection of a directly connected planetary cone-disk type stepless speed changer, belonging to the technical field of stepless speed reducers. Background technique [0002] At present, the direct-connected planetary cone-disc continuously variable transmission has been widely used due to its advantages of small size, large output torque, and stepless wide-range speed regulation during operation. It consists of a transmission mechanism, a pressurizing device, a speed control mechanism and a frame. Its structure is a group of planetary cones (usually 3 to 7) uniformly arranged in the circumferential direction in the friction transmission mechanism. The planetary cones revolve outside the radial direction. The end is clamped between the fixed ring and the flywheel, and the inner end is clamped between the pressure ring and the driving wheel. The radial position of the planetary cone revolution is positioned by the clamp...
