Abstract
A kind of stepless speed-regulating belt sheave of motor,By speed ratio adjustment handwheel (1),Bearing (2),Planet carrier (3),Pulley groove hub (4),Steel ball (5),Compression plate (6),Spring base (7),Small ball (8),Small ball gland (9),Spring (10),Bearing (11) and motor axle sleeve (12) composition,It is directly installed on the output shaft of motor with motor axle sleeve (12),Rotation speed ratio adjustment handwheel (1) can make belt pulley realize stepless speed regulation,The method for rotating speed ratio adjustment handwheel both can be used manual,Electric drive can also be used,To realize automatic speed regulation,Stepless speed-regulating belt sheave has compact-sized,It is small,Light weight,Stable working,The rotating speed of motor output can be made to be finely adjusted according to the use of equipment needs,It can also be under conditions of not changing current speed reducer speed ratio,The rotating speed of the output shaft of speed reducer is dropped to lower,The function of frequency converter and adjustable frequency motor can be substituted,And solid reliable price is low,Therefore there is good economic benefit.
Description
One, technical field
A kind of stepless speed-regulating belt sheave of motor of the present invention belongs to a critical piece of mechanical equipment.
Two, background technology
Used motor pulley as shown in Fig. 2, motor output rotating speed cannot needed for the use according to equipment into
Row fine tuning, can not under conditions of not changing current speed reducer speed ratio, the rotating speed of the output shaft of speed reducer is dropped to it is lower, when
Preceding this function frequency converter and adjustable frequency motor realize that frequency converter can change motor in a certain range
Rotating speed, but be the speed adjustable range upper limit the shortcomings that frequency converter be more than 10%, when lower limit is less than 30%, magnetic field, performance of operating condition, heat dissipation
Etc. can deteriorate, heating burnout is even resulted in, and expensive, short life turns because the invention one kind can reduce motor output
Speed and the stepless speed-regulating belt sheave for carrying out rotating speed fine tuning will be very necessary.
Three, invention content
The object of the present invention is to provide a kind of stepless speed-regulating belt sheaves of motor, mainly by speed ratio adjustment handwheel, bearing,
Planet carrier, pulley groove hub, steel ball, compression plate, spring base, small ball, small ball gland, spring, bearing, motor axle sleeve group
At.Stepless speed-regulating belt sheave is directly installed on motor axle sleeve on the output shaft of motor.One end spiral shell of pulley groove hub
Bolt is fixedly connected with planet carrier, be mounted on speed ratio adjustment handwheel bearing on, speed ratio adjust handwheel sleeve motor reel set on simultaneously
It is connected thereto with screw thread.The other end of pulley groove hub is supported on the small ball of the spring base of compression plate, and spring base is mounted in again
On the bearing of motor axle sleeve, the spring in spring base withstands on the rear end of compression plate, and compression plate is made to remain enough always to steel ball
Pressure, the tail portion of spring base holds out against on the shell of motor, prevents compression plate from being rotated as motor axle sleeve rotates.Speed
Front end than adjusting handwheel is cone, and steel ball is mounted between planet carrier, compression plate and the cone of speed ratio adjustment handwheel, planet carrier
The radius of curvature of working surface is slightly larger than the radius of steel ball.When rotating speed ratio adjustment handwheel, centrum contacts half with steel ball and passes through
It will change, the contact point of steel ball and planet carrier working surface changes therewith, leads to the rotating speed of planet carrier and pulley groove hub
Change.
Four, it illustrates
Fig. 1 is the structure principle chart of speed-regulating pulley.
Fig. 2 is the structure chart of old-fashioned belt pulley
Five, specific implementation mode
The embodiment of the present invention is further described below according to attached drawing 1, referring to Fig. 1, a kind of stepless speed regulation skin of motor
Belt wheel, by speed ratio adjustment handwheel (1), bearing (2), planet carrier (3), pulley groove hub (4), steel ball (5), compression plate (6), spring
Seat (7), small ball (8), small ball gland (9), spring (10), bearing (11) and motor axle sleeve (12) composition.Stepless speed regulation
Belt pulley is directly installed on motor axle sleeve on the output shaft of motor, one end bolt and planet of pulley groove hub (4)
Frame (3) is fixedly connected, and is mounted on the bearing (2) of speed ratio adjustment handwheel (1), and speed ratio adjusts handwheel (1) and motor axle sleeve
(12) it is threadedly coupled.The other end of pulley groove hub (4) is supported on the spring base (7) of compression plate (6) by small ball (8)
On, for spring base (7) on the bearing (11) of motor axle sleeve (12), the spring (10) in spring base (7) withstands on compression plate (6)
Rear end, make compression plate (6) maintain enough pressure, the tail portion of spring base (7) to withstand on the shell of motor always steel ball (5)
On, to prevent compression plate (6) from being rotated with the rotation of motor axle sleeve (12).The front end that speed ratio adjusts handwheel (1) is cone, steel
Ball (5) is mounted between planet carrier (3), compression plate (6) and the cone of speed ratio adjustment handwheel (1), the working surface of planet carrier (3)
Radius of curvature is slightly larger than half warp of steel ball (5).When rotating speed ratio adjustment handwheel (1), centrum is straight with steel ball (5) contact position
Diameter changes, and steel ball (5) changes therewith with the contact point along planet carrier (3) working surface, makes planet carrier (3) and pulley groove
The rotating speed of hub (4) changes.
, stepless speed-regulating belt sheave is compact-sized, small, light weight, stable working, the rotating speed of motor output can be made according to setting
Standby use needs are finely adjusted, moreover it is possible under conditions of not changing current speed reducer speed ratio, turn of the output shaft of speed reducer
Prompt drop can substitute the function of frequency converter and adjustable frequency motor, and solid reliable price is low to lower, therefore with warp well
Ji benefit.
