Embodiment 2

[0050] In combination with Embodiment 1, the installation method of the pin tooth positioning flange includes:

[0051] 1) Install one of the needle-tooth positioning flanges 25, install the positioning pin 26 on the positioning groove 31 inside the housing 3, and align the flange positioning groove 251 of the needle-tooth positioning flange 25 with the positioning pin 26 on the positioning groove 31 Cooperate to position the pin-tooth positioning flange 25, which plays the role of positioning and also plays the role of anti-rotation;

[0052] 2) After positioning, cold fit the pin tooth positioning flange 25. After the installation is completed, install the pin tooth pin 4, cycloidal wheel 5, output seat 9 and input shaft 1. After the installation, install the second pin tooth Locate the flange 25, the installation method is the same as above, and the installation sequence is to prevent the problem that the cycloidal wheel 5 cannot be installed during installation;

Abstract

The invention discloses an output mechanism and a speed reducer. A shell, an output, a base and an input shaft are involved, wherein the input shaft is provided with an eccentric wheel, the eccentricwheel is connected with a cycloid wheel through a crank bearing correspondingly, a plurality of pin tooth pins are arranged on the inner wall of the shell along the circumference, the pin tooth gear pins are intermittently meshed with the cycloid gear, a positioning flange is arranged at the outer end of the output base, the positioning flange is in a T shape, one end of the positioning flange sleeves the output base, and the other end of the positioning flange is provided with a tensioning flange base; and a contraction joint is arranged on the tensioning flange base, the upper end of the tensioning flange base is cylindrical, the lower end of the cylindrical shape is a conical surface which contracts downwards, and the positioning flange is connected to the shrunk conical surface of thetensioning flange base in a sleeved mode. The positioning flange is provided with a conical surface matched with the outer side surface of the tensioning flange base, a clamping sleeve adopted is a coupling, the assembling and disassembling are simple, rapid and convenient.

Description

technical field [0001] The invention relates to a reducer, in particular to an output mechanism and a reducer. Background technique [0002] Pin-toothed cycloidal reducers have been widely used as transmission devices for industrial robots. Because the cycloidal pin gear reducer adopts a planetary transmission structure with less tooth difference, it has the advantages of small size, light weight, large transmission ratio range, stable operation and strong bearing capacity, etc., but the structure of the general pin gear cycloidal reducer is complex . [0003] At present, the output seat of the pin-toothed cycloidal reducer is generally a shaft output device, a peripheral output device, and a flange output device. When the shaft output device is used, the connection accuracy of the coupling is generally poor. If there is a deviation in the reducer, the general The coupling will not be able to carry out precise transmission, and the general flange connection is connected by...
