Description
Technical field
The present invention relates to the technical fields that machine driving is slowed down, more specifically to a kind of cycloid disc of speed reducer.
Background technology
In the design of all kinds of gearings, speed reducer is essential link.Speed reducer is a kind of relatively accurate machine
Tool, the purpose using it are to reduce rotating speed, increase torque.Its type is various, according to actuation types can be divided into gear reduction unit,
Worm reducer and planetary reducer.Wherein, cycloidal planetary gear speed reducer is due to having many advantages, such as that reduction ratio is greatly and small
And gear reduction unit and worm decelerating machine are gradually substituted, and turn of speed and torque is widely used in as driving or deceleration device
In exchange device.
Cycloidal planetary gear speed reducer is a kind of application planetary drive principle, using the novel transmission dress of cycloidal pin teeth engagement
It sets, deceleration transmission component is using circle-arc tooth and needle roller Cylindrical Surfaces Contact, still, since the power of speed reducer transmits contact surface
Motion process is to be moved in the form of high load capacity, therefore be easy to cause abrasion.And its is complicated, and requirement on machining accuracy is high,
Will be there are certain process gap during design and installation, rotation is not steady enough when leading to work, and noise is big, rotational efficienty
It is low.So it is necessary to propose a kind of novel cycloid speed reducer to solve the above problems now.
However, cycloid disc is the component transmitted for realizing power in cycloid speed reducer, the design of structure can direct shadow
Ring deceleration and the transmission performance of speed reducer.The circumference of the cycloid disc of existing cycloidal planetary gear speed reducer is processed as continuous circle-arc tooth,
For being engaged with needle roller cylindrical surface, but the processing of this continuous circular arc tooth causes difficulty of processing greatly and consumes length when processing.Meanwhile
Existing cycloidal planetary gear speed reducer is to need the positive side for distinguishing cycloid disc that can just carry out speed reducer with face of tossing about in use
Assembling, such cycloid disc two sides difference not only further increases difficulty of processing, increases production cost；And the cycloid disc is logical
It is low with property, install and use inconvenience.
Invention content
It is an object of the invention to overcome shortcoming and deficiency in the prior art, provide a kind of simple in structure, easy to process
With versatile speed reducer cycloid disc, the component which transmits as speed reducer power is not necessarily in use
It distinguishes positive side and face of tossing about also improves its convenience used to reduce difficulty of processing and manufacturing cost.
In order to achieve the above object, the technical scheme is that：A kind of cycloid disc of speed reducer, packet
Include disk body, it is characterised in that：The mounting hole and through-hole for installing input shaft are provided in the disk of the disk body；The disk body
Positive side be provided with the track groove one rolled for ball, the face of tossing about of disk body is provided with the track groove rolled for ball
Two；The track groove one is identical with two shape of track groove.
In the above scheme, the positive side of the disk body of cycloid disc of the present invention and the face of tossing about are provided with the identical track groove of shape one
With track groove two, to solve, existing cycloid disc processing continuous circular arc tooth causes difficulty of processing big and long processing time is asked
Topic.Simultaneously as track groove one is identical with two shape of track groove, therefore, which not only reduces difficulty of processing and production is made
This is caused, and versatile, positive side is not needed to distinguish in speed reducer assembling process and face of tossing about then can be used as speed reducer
Power transfer member, to improve the convenience that it is used.
More specifically, the track groove one and track groove two are arranged along the circumference of disk body, and track groove one is opened in disk
It is corresponding that the position of the positive side of body and track groove two are opened in the disk body position in face of tossing about.The present invention is due to track groove one and track
The shape of slot two is identical with position is opened up, therefore in cycloid disc process of manufacture, and a form of mold can be used
Processing is formed, and the production cost of cycloid disc is greatly reduced.
It is in "U" shaped groove, slot diameter R and the rolling of "U" shaped groove that the track groove one, which is cross section with track groove two,
The outer diameter of pearl matches.The positive side of the cycloid disc and the track groove one and track groove two of face setting of tossing about are identical track
Therefore slot does not need to distinguish the obverse and reverse of cycloid disc when speed reducer assembles, to reduce the difficulty of processing of cycloid disc, make
Obtain agility and convenience easy to process, and that speed reducer assembling can be improved.
The track groove one forms the cycloid closing guide groove with wave number on the positive side of disk body；Track groove two is in disk body
Face of tossing about on formed with wave number cycloid close guide groove.
The wave number of the track groove one is equal with the wave number of track groove two.The wave number and ball of the track groove one of the present invention
There is quantity difference, the wave number of track groove two and the quantity of ball to have difference.The wave of track groove one and track groove two of the present invention
Number can quantity more than the quantity of ball or ball can be more than the wave number of track groove one and track groove two, in this way design
The reduction ratio that speed reducer can be increased is also beneficial to the simplification and processing of machinery.If the wave number of track groove one and track groove two with
The quantity of ball is identical, then ball, which can not achieve, is rolled or slided in track groove one and track groove two, and pendulum is cannot achieve
The engagement of the positive side of drum and upper enclosure end face, the engagement in the toss about face and lower casing internal end surface of cycloid disc, also without
The active force of deceleration is reacted on cycloid disc by method, to which speed reducer cannot play the role of deceleration.
The input shaft is linear axis, and the mounting hole is the mounting hole for installing linear axis, and mounting hole is located at disk body
Middle part.
The through-hole is the through-hole for installing bearing, and disk body is by bearing in the bent axle for being socketed on speed reducer in through-hole
On；The through-hole is evenly spaced on centered on mounting hole on disk body.
The disk body is additionally provided with the mounting hole for fixing speed reducer output mechanism.
Another technical solution is：The input shaft is bent axle, and the mounting hole is the mounting hole for installing bearing, disk body
By bearing in being socketed on input shaft in mounting hole；Mounting hole is located at the middle part of disk body.
The through-hole is the through-hole for installing linear axis, and the through-hole is evenly spaced on centered on mounting hole in disk
On body；The aperture of the through-hole is more than the diameter of axle of linear axis.
Compared with prior art, the invention has the advantages that and advantageous effect：
1, the positive side of the disk body of the cycloid disc of speed reducer of the present invention and the face of tossing about are provided with identical one and of track groove of shape
Track groove two, to solve the problems, such as that existing cycloid disc processing continuous circular arc tooth causes difficulty of processing big and long processing time.
2, the cycloid disc of speed reducer of the present invention not only reduces difficulty of processing and manufacturing cost, but also versatile,
The power transfer member that positive side then can be used as speed reducer with face of tossing about is not needed to distinguish in speed reducer assembling process, to improve
Its convenience used.
