Description
One, technical field
The utility model relates to electronic stepless speed-regulating belt sheave, belong to a main component of mechanical equipment.
Two, background technique
Used motor pulley as shown in Fig. 2, motor output revolving speed cannot according to needed for the use of equipment into
Row fine tuning, can not under conditions of not changing current speed reducer speed ratio, the revolving speed of the output shaft of speed reducer is dropped to it is lower, when
This preceding function is realized with frequency converter and adjustable frequency motor, and frequency converter can change motor in a certain range
Revolving speed, but be the speed adjustable range upper limit the shortcomings that frequency converter be more than 10%, when lower limit is lower than 30%, magnetic field, performance of operating condition, heat dissipation
Etc. can deteriorate, heating burnout is even resulted in, and expensive, the service life is short, turns because the invention one kind can reduce motor output
Speed and the stepless speed-regulating belt sheave for carrying out revolving speed fine tuning will be very necessary.Patent Office of the People's Republic of China announces special on August 10th, 2018
Benefit application No. is 2018101448352 " a kind of stepless speed-regulating belt sheave of motor ", tested realize substantially it is stepless
Speed regulation, but using the mode of artificial spanner handle, the output revolving speed for adjusting belt pulley has to shutdown descendant and carries out at the scene
Operation, be not able to satisfy do not shut down or remote operation needs, the purpose of the utility model is to provide a kind of electronic stepless-adjustments
Fast belt pulley can be such that the output revolving speed of belt pulley realizes and not shut down or long distance wireless adjust automatically, especially suitable for oil field
The pumping unit of oil recovery under conditions of unattended according to the variation automatic adjusting oil production speed of oil well output, to reduce energy consumption
And cost for oil production.
Three, summary of the invention
The purpose of the utility model is to provide a kind of electronic stepless speed-regulating belt sheaves, mainly adjust handwheel, planet by speed ratio
Frame, pulley groove hub, steel ball, compression plate, spring, spring base, motor axle sleeve, feather key, turbine body and worm screw composition.Nothing
Grade speed-regulating pulley is directly installed on the output shaft of motor with motor axle sleeve.One end bolt and row of pulley groove hub
Carrier is fixedly connected, and is mounted on speed ratio adjustment handwheel, and speed ratio adjusts handwheel thread bush on motor reel set, speed ratio adjustment
The front end of handwheel is cone, and rear end is worm gear, and the transmission that worm gear and worm screw form a worm-drive is paid, and worm screw uses radio
Driving.The other end of pulley groove hub is supported on the spring base for being equipped with spring and compression plate, and spring base is mounted in motor again
On axle sleeve, using being keyed, spring withstands on the rear end of compression plate, and compression plate is made to maintain foot always to steel ball for compression plate and spring base
Enough pressure holds out against the tail portion of spring base on the shell of motor, steel to prevent spring base from motor axle sleeve being followed to rotate
Between planet carrier, compression plate and the cone of speed ratio adjustment handwheel, the radius of curvature of the working surface of planet carrier is slightly larger than ball
The radius of steel ball.When worm screw through worm-drive pay make speed ratio adjust hand wheel rotating when, under the driving of screw thread with motor reel
It covers and is axially generating relative displacement, speed ratio adjustment handwheel cone contacts half with steel ball through changing, and steel ball and planet carrier work
The contact point on surface also changes therewith, and the revolving speed of planet carrier motor output shaft opposite with pulley groove hub is caused to change,
To achieve the purpose that adjust speed ratio.
Four, Detailed description of the invention
Fig. 1 is the structure principle chart of electronic stepless speed-regulating belt sheave.
Fig. 2 is the structure chart of old-fashioned belt pulley.
Five, specific embodiment
The embodiments of the present invention are further described below according to attached drawing 1, referring to Fig. 1, electronic stepless speed-regulating belt sheave
By speed ratio adjustment handwheel 1, planet carrier 2, pulley groove hub 3, steel ball 4, compression plate 5, spring 6, spring base 7, motor axle sleeve 8,
Feather key 9, worm gear shell 10 and worm screw 11 form, and electronic stepless speed-regulating belt sheave motor axle sleeve 8 is directly installed on motor
Output shaft on, one end bolt of pulley groove hub 3 be fixedly connected with planet carrier 2 is mounted on speed ratio adjustment handwheel 1 on, speed
It is threadedly coupled than adjustment handwheel 1 with motor axle sleeve 8, the front end that speed ratio adjusts handwheel 1 is cone, and rear end is made worm gear, snail
The transmission that wheel forms a worm-drive with worm screw 11 is paid, and the feather key 9 of worm gear shell 10 is connect with motor axle sleeve 8, belt pulley
The other end of slot hub 3 is supported on the spring base 7 equipped with spring 6 and compression plate 5, and spring base 7 is mounted on motor axle sleeve 8,
Tail portion is withstood on again on the shell of motor, and spring 6 withstands on the rear end of compression plate 5, and compression plate 5 is made to remain enough always to steel ball 4
Pressure, steel ball 4 mounted in planet carrier 2, compression plate 5 and speed ratio adjustment handwheel 1 cone between, the working surface of planet carrier 2
Radius of curvature is slightly larger than half warp of steel ball 4, when worm screw 11 pays rotation speed ratio adjustment handwheel 1 through worm-drive, cone and steel
The diameter of 4 contact position of ball changes, and steel ball 4 changes therewith with along the contact point of 2 working surface of planet carrier, makes pulley groove hub
The revolving speed of 3 opposite motor output shafts changes, to achieve the purpose that speed regulation.
The stepless speed-regulating belt sheave of motor compact-sized small in size, light weight, can make motor output at stable working
Revolving speed is finely adjusted according to the use of equipment needs, moreover it is possible under conditions of not changing current speed reducer speed ratio, speed reducer
The revolving speed of output shaft drops to lower, can substitute the function of frequency converter and adjustable frequency motor, and solid reliable price is low, therefore has
There is good economic benefit.
