Abstract
The invention discloses an RV reducer based on a particle damping shell. The RV reducer comprises the shell and a cycloidal gear. Holes are punched in the upper portion and the lower portion of the edge of the shell, abrasion-resistant rubber interlayers are embedded, a certain quantity of damping particles are packed in the interlayers, and then the two ends are sealed. According to the RV reducer, a damping effect is achieved through collision between the damping particles on the edge of the shell as well as between the damping particles and the inner wall of the shell, and vibration caused by sudden stopping and sudden starting in the working process of the RV reducer is attenuated in time. The RV reducer is reasonable in structure, good in damping effect, and capable of prolonging the service life of main parts and components, and the transmission stability and accuracy of the RV reducer are improved.
Description
Technical field
The invention belongs to precision speed reduction device field, be specifically related to a kind of RV retarder based on particle damping shell.
Background technique
As a kind of emerging type of belt drive, RV transmission based on traditional Cycloid drive, and has plurality of advantages: gear range is large, transmission efficiency is high, volume is little, lightweight, bearing capacity is strong, kinematic accuracy is high, the life-span is long, output mechanism rigidity is large.Current RV retarder is applied increasingly extensive in industrial robot, particularly transmission accuracy is had to the robot field of high requirement.
Some shortcomings that domestic RV retarder has: 1. lack precision machining equipment, the required precision of RV reducer gear is higher, but domestic manufacturer lacks corresponding manufacturing equipment, and there is blockade on new techniques; Easily produce vibration & noise during the running of 2.RV retarder, particularly industrial robot suddenly stops at work, anxious startup can produce impact force, causes the series of problems such as needle roller and up-downgoing carrier, cover attack.Can produce vibration & noise during current domestic RV retarder running, cause galloping, working life, transmission accuracy, dynamic characteristic are all poor compared with imported product.
For some above-mentioned problems, the vibration & noise produced when how to suppress RV retarder to operate, reduces needle roller and up-downgoing carrier is collided, and the working life of improving kinematic accuracy and main parts size is the difficult point of designing for manufacturing RV retarder.
Summary of the invention
The object of the invention is to utilize particle damped vibration attenuation technology to provide a kind of smooth running, the RV retarder based on particle damping shell that noise is low.
Its technical solution is as follows:
Based on the RV retarder of particle damping shell, comprise bent axle 1, input shaft 2, flange 3, needle roller 4, output mechanism 5, shell 6 and cycloid wheel 7, wherein: shell 6 center is provided with input shaft 2, the both sides of described input shaft 2 are meshed with the bent axle 1 of symmetrical distribution by gear, two bent axles 1 respectively by bearings in the endoporus of flange 3 and output mechanism 5.It is in the cycloid wheel 7 of 180 ° that bent axle 1 is connected to two panels phase difference by bearing; Flange 3 and output mechanism 5 are connected by pin connection, and needle roller 4 half is embedded in pin perforation uniform on shell 6.Output mechanism 5 is promoted by the spring bearing of bent axle 1, transmits rotating speed and moment of torsion; Described shell 6 edge is drilled with some holes in place up and down, is inlaid with abrasive rubber interlayer 8 in each hole, and according to concrete operating mode, each abrasive rubber interlayer 8 is built with some vibration damping particles 10, and each hole opening is by mounting 9 seal wear-resistant rubber interlayer 8.
In the present invention, the attributes such as the kind of the vibration damping particle of described abrasive rubber interlayer inside, quantity and size can be placed according to situations such as RV retarder size and application places, its kind comprises plastics, rubber etc., the 40-92% of its quantity duty cavity volume, its diameter is 0.01mm-1mm, makes it have larger dampening range and Applicable scope.
Beneficial effect of the present invention is: the present invention utilizes working principle and the optimization method of damping particles vibration damping, RV retarder is made to have the overall characteristics such as good vibration damping: 1. shell, boring is located up and down at shell edge, be inlaid into symmetrical abrasive rubber interlayer, a certain amount of vibration damping particle is loaded, then welded seal two ends in interlayer; 2. vibration damping particle, according to conditions such as RV retarder applications, adopts the spherical vibration damping particle of different materials, quantity and size, and is placed in abrasive rubber interlayer; 3. abrasive rubber interlayer, inlays abrasive rubber interlayer at the inwall place, hole that shell edge is located up and down, reduces particle and hole inwall and collides the noise produced, raising damping and particle working life.Structure of the present invention is simple, reasonable in design, and the noise and vibration produced when can reduce the work of RV retarder, reduces making and installation difficulty.Improve transmission accuracy and the stationarity of RV retarder.
