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
The spline that the present invention relates to a kind of direct-connected planetary conical disc type stepless reducer connects, and belongs to mechanical stepless speed reducer technical field.
Background technique
At present, direct-connected planetary conical disc type stepless reducer is little with its volume, output torque is big, the advantages such as carrying out stepless speed governing on a large scale that can be in operation is used widely, planetary conical disc type stepless reducer is by motor, slip gear, pressurization device and speed regulation control mechanism and frame are formed, its structure is one group of planetary bevel-type (being generally 3～7) of circumferentially evenly arranging in the slip gear, planetary bevel-type revolution radial direction outer end is clipped between retaining ring and the flywheel, the inner is clipped between pressure ring and the driving wheel, location, planetary bevel-type revolution clamping gap, the inner outer end of radial position, to pressure ring end face pressurization the outer end is all stepped up with belleville spring, each planetary bevel-type axle inserts in the slide block also free to rotate, slide block places the radial groove of planet carrier and can be free to slide along groove, and driving wheel supports by planetary bevel-type under free state, the location.Driving wheel is located by motor output shaft when variable-speed motor is connected with motor, by the flat key transferring power, the shortcoming of its existence is: the cooperation in axle and hole is tighter transition fit or interference fit when connecting owing to the employing flat key, matching gap is less, and owing to there is following error in reasons such as processing, assembly precision: 1. rely on the axis of the driving wheel of planetary bevel-type location to produce skew, coaxiality error occurs with the design axis; 2. rely on the axis and the planetary bevel-type radial direction of the driving wheel of planetary bevel-type location to produce the error of perpendicularity; 3. there is coaxiality error between motor output shaft and the adpting flange; 4. there is the error of perpendicularity between motor output shaft and the adpting flange; 5. there were coaxiality error in motor output shaft and variable-speed motor driving wheel when motor and variable-speed motor assembled; 6. there were parallelism error in motor output shaft center line and variable-speed motor driving wheel center line when motor and variable-speed motor assembled.The effect of the peripheral force when these error actings in conjunction make driving wheel not only be subjected to proper functioning, also can be subjected to the effect of radial force owing to coaxiality error causes driving wheel, because the error of perpendicularity causes driving wheel axially being subjected to the moment of flexure effect, the radial force that driving wheel is subjected to departs from it and relies on the planetary bevel-type centered positions, make the planetary bevel-type unbalance stress, indivedual planetary bevel-types occurring skids, driving wheel is delivered to planetary bevel-type in the moment of flexure that axially is subjected to, planetary bevel-type is on-stream to be subjected to the alternate torque effect, the operation noise is big, accelerated wear test, even damaged, serious harm equipment proper functioning.
Summary of the invention
For overcoming the shortcoming that above-mentioned linkage structure exists, the purpose of this invention is to provide a kind of to making and the assembly precision requirement is low, stressed evenly, bearing capacity is strong, noise is low, the spline direct-connected planetary conical disc type stepless reducer of long service life.
The present invention is achieved by the following technical solutions: direct-connected planetary conical disc type stepless reducer driving wheel endoporus adopts internal spline, motor output shaft adopts external splines, motor output shaft adopts spline directly to be connected with the variable-speed motor driving wheel, spline tooth number is more than 2 or 2, spline connects employing bigger radial clearance and sideshake, to eliminate the influence that the coaxiality error between motor output shaft and the direct-connected planetary conical disc type stepless reducer driving wheel and the error of perpendicularity cause to proper functioning, the variable-speed motor driving wheel is bearing radial force and axial moment of flexure no longer, only transmit the work peripheral force, radial clearance the best is got 0.25mm～1mm, and sideshake the best is got 0.25mm～1mm.
Because spline is connected to multiple tooth work, bearing capacity height, transmitting torque are stablized.
The present invention has manufacturing compared to existing technology and the assembly precision requirement is low, stressed evenly, bearing capacity is strong, noise is low, the advantage of long service life.
Description of drawings
Fig. 1 is spline direct-connected planetary conical disc type stepless reducer of the present invention and motor connection diagram.
Fig. 2 is the cross-sectional end view that spline direct-connected planetary conical disc type stepless reducer of the present invention is connected with motor.
