Description

Novel flexible compensation type gear robot speed reducer
Technical Field
The invention relates to the field of speed reducers, which compensates errors such as return difference generated in the rotation process of an RV speed reducer and abrasion generated in the operation process by increasing the eccentricity of a crankshaft, selecting materials with smaller elastic coefficients, designing the structure of a pin gear shell into a net structure and the like.
Background
RV speed reducer is widely used in electromechanical transmission represented by industrial robots due to the characteristics of compact structure, large reduction ratio, good rigidity and the like, and is a high-precision speed reduction transmission device. The RV reducer is actually a two-stage reduction transmission mechanism formed by combining an involute planetary transmission mechanism and a cycloidal pin gear planetary transmission mechanism, an output shaft of the RV reducer is a low-speed shaft, and an output mechanism (i.e. a planet carrier) is pushed by three pairs of crankshaft support bearings arranged on the output mechanism to transfer rotation vectors on cycloidal gears out at a speed ratio of 1:1. The transmission error generated in the whole transmission process can be directly reflected on the output shaft, so the transmission precision of the cycloidal pin gear is a key factor for determining the precision of the RV reducer.
At present, aiming at improving the performance of the RV reducer transmission system, the transmission precision is mainly improved through the modification of a cycloid gear, in theory, the transmission between the cycloid pin gear tooth profile of a standard gear and the pin gear teeth belongs to gapless meshing, but due to the fact that errors such as manufacturing and installation cannot be compensated, a plurality of problems can be generated in the transmission process; therefore, errors generated in the manufacturing and mounting processes are compensated by the method of shaping in the processing process of the cycloidal gears at home and abroad, and reasonable radial backlash is ensured, but return difference can be generated in the transmission process, and the transmission precision is seriously affected. The technical problems of tooth profile modification, manufacturing precision control, process parameter optimization, technical index pre-control and the like are successfully solved at home and abroad, the series of technology is used as a secret core technology, the theory and experimental research of the technology cannot be used as a reference, the development of RV reducers in China is severely restricted, and the import of the reducers in domestic robots is mostly restricted.
Disclosure of Invention
The invention aims to provide a device capable of compensating errors generated in the manufacturing, mounting and working processes, reducing return difference and compensating errors caused by factors such as abrasion.
The technical scheme adopted for realizing the purpose of the invention is that the novel flexible compensation type gear robot speed reducer consists of a front stage and a rear stage of a planetary gear speed reducer.
The cycloidal pin gear speed reducer is characterized in that in the rear-stage assembly structure, the pin gear shell of the rear stage of the cycloidal pin gear speed reducer of the existing RV speed reducer is replaced by a flexible pin gear shell, the cycloidal gear is replaced by an involute gear, and the eccentric distance of a crank shaft is increased.
The inner ring of the flexible needle gear housing is provided with a circular flange. The annular flange is provided with a plurality of meshes to form an annular net structure of the inner ring of the needle gear housing. The mesh structure has elasticity. The annular flange has inner involute gear teeth on a circumference facing the center of the flexible pin housing.
The involute gear has outer involute gear teeth that mesh with inner involute gear teeth.
The eccentricity of the crank shaft is increased so that the installation of the inner involute gear teeth and the outer involute gear teeth is interfered, and the flexible pin gear shell is extruded to be elliptical.
Further, the flexible needle gear shell is made of a composite material and can be divided into an inner layer and an outer layer. The inner layer includes an annular flange portion.
Further, the inner layer material is selected from 20CrMnTi or 30CrMnSi materials. The outer layer material is selected from 65Mn spring steel.
Further, the involute gear is a modified involute gear, and the change range of the modified coefficient is-0.2 mm to +0.5mm.
Further, the eccentricity of the crankshaft is increased relative to the eccentricity of a standard crankshaft in the RV reducer, the range of the eccentricity is 0.05-0.2 mm, the eccentricity is flexibly selected according to the specification of the reducer,
Further, the crank shaft eccentricity is L1. The eccentricity of the standard crankshaft in the RV retarder is L2.
The novel flexible compensation type gear robot speed reducer is not changed at the involute planetary gear transmission part, so the description is omitted, and the working principle and the working process of the compensation return difference of the novel flexible compensation type gear robot speed reducer are as follows:
The working principle of the compensation return difference of the novel flexible compensation type gear robot speed reducer is as follows: firstly, the difference of the structure determines the difference between a novel flexible compensation robot reducer and a traditional RV reducer, the eccentric distance of a crank shaft of the novel flexible compensation robot reducer is increased by 0.1mm, the pin gear housing deforms when being installed through the cooperation with a flexible pin gear housing, the pin gear housing is deformed from a round shape to an oval shape, at the moment, because the pin gear housing deforms, elastic force exists on the pin gear housing in the running process of the reducer, and the intersecting line direction of a plane formed by the central lines of two outer involute gears meshed with the pin gear housing and the tooth surface of the outer involute gear is the direction of the long diameter of the pin gear housing after the deformation, namely the direction of the elastic force; and secondly, because the eccentric directions of the two eccentric shaft parts of the crank shaft are symmetrical along the axis and form an included angle of 180 degrees, the two external involute gears and the axis of the crank shaft are positioned on the same plane, the long diameter of the needle gear shell moves along with the movement of the two external involute gears in the movement process of the speed reducer, the rotation direction is the same as the rotation direction of the crank shaft, the elastic force can rotate along with the rotation of the long diameter of the needle gear shell, the elastic force is always the same as the direction of the long diameter, and the pressure exists on the two external involute gears in the long diameter direction of the needle gear shell all the time.
The working process of the novel flexible compensation type gear robot speed reducer is as follows: the RV speed reducer firstly carries out first-stage transmission, namely involute planetary gear transmission, wherein the shaft where a sun gear is positioned is used as an input shaft, and the shaft where a planetary gear is positioned is used as an output shaft (namely a crank shaft); the second stage transmission is entered, the input shaft at this moment is a crank shaft, an external involute gear is arranged at the eccentric part of the crank shaft through a rolling bearing, when the crank shaft continuously moves along a certain direction, the external involute gear always has certain pressure on the pin gear shell, at this moment, the length of the long diameter of the pin gear shell is unchanged theoretically, and at this moment, the transmission precision of the novel flexible compensation type gear robot reducer is the same as that of the traditional RV reducer; when the direction change is needed, the common RV reducer can generate return difference, so that the transmission precision is affected, and the hypocycloidal gear and the pin gear housing are in a non-contact state at a time interval of generating the return difference; the pin gear shell of the novel flexible compensation type gear robot reducer has elastic force, when return difference is generated, the long diameter of the pin gear shell can be reduced under the action of the elastic force, and the gap of the section generating the return difference is compensated, so that the transmission precision is improved. The design of the novel flexible compensation gear robot reducer mainly aims at solving the problem that the robot reducer generates return difference and compensating manufacturing and installation errors. Furthermore, changing the needle gear housing to a flexible needle gear housing has the following advantages:
1. The number of teeth is increased, and the transmission precision is improved. The flexible pin gear housing becomes elliptical under the action of the outer involute gear, i.e., stretches along the centerline of the outer involute gear to lengthen, narrows in the vertical direction, and narrows gradually from the center along the long diameter direction, with the shortest at both ends of the long diameter. Therefore, the gears which cannot be meshed when the pin gear housing is not deformed can be meshed after the pin gear housing is deformed and narrowed, so that the meshing number of the reducer is increased, and the transmission precision is improved.
2. Noise is reduced. The common robot reducer part is a rigid part, noise can be generated when collision occurs, and the pin gear housing of the novel flexible compensation type robot reducer is a flexible element, so that the functions of buffering and vibration absorption can be achieved, and the noise is reduced.
The technical effects of the invention are undoubted:
1) The flexible needle gear housing is used, return difference and the like generated in the motion process are compensated under the action of the elastic force of the needle gear housing, and the transmission precision is improved;
2) Radial errors in the manufacturing and mounting processes can be effectively compensated, the deformation of the pin gear housing is a continuous process, and when the radial errors occur in the manufacturing and mounting processes, the errors can be compensated, so that the reject ratio is reduced;
3) The number of meshing teeth is increased, and the transmission precision is improved;
4) Damping and shock absorption, and reducing noise.

The inner layer material is selected from 20CrMnTi or 30CrMnSi materials, and is processed into an inner gear. The outer layer is a flexible portion. The outer layer material is selected from 65Mn spring steel, so that the elastic coefficient of the material is ensured to be smaller, and meanwhile, the outer layer is processed into a net structure, so that the elastic coefficient of the material is reduced, and the fatigue life is prolonged.
The involute gear has outer involute gear teeth 301 that mesh with inner involute gear teeth 202. The involute gear is provided with a deflection coefficient range of-0.2 mm to +0.5mm.
The crank axle eccentricity increases such that there is interference with the installation of the inner involute gear teeth 202 and outer involute gear teeth 301, squeezing the flexible pin housing into an oval shape. In the embodiment, the eccentricity of the crankshaft is increased relative to the eccentricity of a standard crankshaft in the RV reducer, the increase range is 0.05-0.2 mm, and the eccentricity is flexibly selected according to the specification of the reducer.
