Description
Technical field
The present invention relates to a kind of retarder, specifically a kind of unidirectional adjustable speed of widely used eccentric wheel bent plate slows down
Device.
Design background
Speed reducer plays a part of to match rotating speed between prime mover and working machine or executing agency and transmits torque, is a kind of
Accurate machinery relatively, the purpose using it are to reduce rotating speed, increase torque.Application field is extremely wide, is related to metallurgy, has
The industries such as color, coal, building materials, ship, water conservancy, electric power, engineering machinery and petrochemical industry.Traditional Speed-adjustable reducer is mostly tooth
Wheel group structure forms a sets of transmission mechanism, to realize the mesh of deceleration using parts such as roller gear, conical gear or worm screws
, such organization volume is big, and quality is heavy and structure is cumbersome, and the accuracy of manufacture requires high.Traditional adjustable speed speed reducer is even more
In this way, on the basis of train of reduction gears, traditional adjustable speed speed reducer is realized using parts such as bent axle, shift fork, planetary gears and is adjusted
The purpose of speed, this also results in the shortcomings of manufacture of Conventional tunable speed speed reducer is difficult, and maintenance period is frequent, maintenance cost is high.
Invention content
The purpose of the present invention is in view of the foregoing drawbacks, provide a kind of unidirectional Speed-adjustable reducer of eccentric wheel bent plate, the deceleration
Device is simple in structure, stable mechanical performance, lightweight and portable in volume and convenient for safeguard.
The technical scheme is that：
The unidirectional Speed-adjustable reducer of eccentric wheel bent plate includes reducer shell, eccentric mechanism, the soldering of bent plate axis, transmission
Handle, one-way shaft bearing, unilateral bearing, output shaft, cylindrical roller, resetting spring, the eccentric wheel of the eccentric mechanism are mounted on
On input shaft, transmission handle is arranged below in eccentric wheel, transmission handle one end is equipped with cylindrical roller, and cylindrical roller is in bent plate axis soldering
It is moved back and forth on bent plate, the other end connects one-way shaft bearing, and unilateral bearing is mounted in one-way shaft bearing, and output shaft is mounted on single
Into bearing, the bent plate of bent plate axis soldering is connect with transmission handle installation one-way shaft bearing one end by resetting spring, input shaft, defeated
Shaft, bent plate axis soldering fixing axle are separately mounted on reducer shell, and pass through oil sealing sealing.
The beneficial effects of the invention are as follows：
1, the reducer structure is simple, stable mechanical performance, and shell uses aluminum alloy materials, light-weight, good heat dissipation and just
In maintenance.
2, the eccentric wheel that this retarder is selected is engineering plastic materials and parts, and material is light, intensity is high, wearability is good, is replaced simple
And manufacturing cost is relatively low.
3, one end of transmission handle is equipped with the roller of rotatable cylindrical type, when input shaft rotates, cylindrical roller and song
Plate friction generates rotation, is rolling friction between the cylindrical roller and bent plate of rotation, extends the service life of part.

Specific implementation mode
The unidirectional Speed-adjustable reducer of eccentric wheel bent plate include reducer shell 1, eccentric mechanism 2, bent plate axis soldering 5,
Be driven handle 3, one-way shaft bearing 6, unilateral bearing 7, output shaft 8, cylindrical roller 4, resetting spring 9, the eccentric mechanism it is inclined
Heart wheel is mounted on input shaft 21, and the eccentric mechanism is mutually 120 degree of angles by three eccentric wheels 22 by anti-rotation hexagonal hole 23
On input shaft, input shaft setting-up eccentricity wheel part is six square shafts, and three eccentric wheels apply pressure to transmission handle successively, push away
Dynamic transmission motion of handle.Transmission handle is arranged below in eccentric wheel, transmission handle one end is equipped with cylindrical roller, and cylindrical roller is welded in bent plate axis
It is moved back and forth on the bent plate of conjunction, the other end connects one-way shaft bearing.One-way shaft bearing is in the figure of eight, and one end passes through axis pin and biography
Dynamic handle connection, the other end install unilateral bearing, and output shaft is mounted in unilateral bearing, the work that output shaft is contacted with unilateral bearing
Face has carried out quenching treatment in processing, increases case hardness and integral strength.The bent plate axis soldering includes round and smooth cambered surface
Bent plate 51, bent plate are connect with 52 soldering of fixing axle, and bent plate and transmission handle installation one-way shaft bearing one end of bent plate axis soldering pass through
Resetting spring connects.Input shaft, output shaft, bent plate axis soldering fixing axle are separately mounted on reducer shell, and pass through oil sealing
Sealing.Three eccentric wheels make the cylindrical roller for being mounted on transmission handle one end to three transmission handle pressures respectively, along the curved surface of bent plate
Movement, the one end of handle equipped with bearing is driven during movement can drive output shaft single direction rotation to form power transmission.Unidirectionally
Bearing block is designed to that the figure of eight, one end install unilateral bearing, and one end is mounted on transmission handle, and can be rotated freely.Transmission
The other end of handle installs a rotatable cylindrical roller, and is connect with bent plate by resetting spring, by eccentric mechanism
Pressure when, the cylindrical roller end for being driven handle can be along bent plate non-plane motion, and one end of movable figure of eight one-way shaft bearing can be with
Output shaft rotates for the center of circle, due to unilateral bearing characteristic, drives output shaft single direction rotation, during the motion, because resetting bullet
The pulling force of spring, cause be driven handle be tightly attached on the wheel face of eccentric wheel, will not there is a situation where eccentric wheel be driven handle sky contact.
In operation process, three eccentric wheels can apply pressure to three transmission handles respectively successively on input shaft, cause output shaft continuous and
Rotation at the uniform velocity.When eccentric mechanism input shaft is rotated, no matter left or right rotation, due to the spy of unilateral bearing
Property, output shaft rotates in one direction always.
Attached drawing 6 is bent plate axis soldering, and one end of bent plate is evenly distributed with three circular holes, and circular hole connects resetting spring, transmission handle is made to exist
It can be sprung back in time when being detached from the pressure that eccentric wheel is given.And it can change the angle of bent plate by adjusting bent plate axis, make transmission
The move distance at handle roller end generates variation, occurs when being driven the distance that handle cylindrical roller moves on bent plate in same time
When variation, variation corresponding can be also generated with the rotating speed of the output shaft of transmission handle other end connection, to play the role of speed governing.
