Embodiment Construction
[0025] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0026] like figure 1 As shown, the bearing-type RV reducer includes a mounting bracket 8 rotatably mounted on a pin gear housing 1, and the inner ring with the smallest inner diameter of the pin gear housing 1 has a number of densely arranged needle roller grooves 2 in an annular array. Slot 2 is a peach slot (see figure 2 and image 3 ); the mounting bracket 8 includes a first unit 5 and a second unit 6 mounted together by means of locking elements (see Figure 4 ), the locking element is a bolt connection, and can also be other connection parts that realize this function. There are ...

The invention discloses a bearing type RV speed reducer, and belongs to the technical field of speed reducers. The speed reducer comprises a pin wheel housing, an installation frame is arranged in the pin wheel housing in a rotary mode, the installation frame is provided with two cycloid gears in transmission connection with the pin wheel housing through needle rollers, the installation frame is rotatably provided with a power input shaft, the power input end of the power input shaft extends out of the installation frame, the power input shaft is provided with two eccentric drive wheels which penetrate through the centers of the two cycloid gears respectively and are matched with the corresponding cycloid gears, the installation frame is rotatably provided with at least two positioning shafts which are symmetric to the rotation center of the power input shaft, and each positioning shaft is provided with two eccentric transmission wheels which penetrate through the two cycloid gears respectively and are matched with the cycloid gears. Power center input and first speed reduction are achieved. Compared with the prior art, the bearing type RV speed reducer reduces the number of power input shafts and use of sun gears and planetary gears, manufacturing cost is low, transmission is reliable, machining and installation are convenient to achieve, and service life is prolonged.
Description
technical field [0001] The invention belongs to the technical field of reducers, and in particular relates to a bearing type RV reducer. Background technique [0002] At present, the commonly used robot RV reducer includes a pin-tooth shell, which is provided with a planetary carrier formed by connecting two monomers through a connecting element, and two cycloidal wheels are arranged between the two monomers. The body is annularly arrayed and correspondingly provided with three bearing positions of tapered roller bearings. The three sets of correspondingly arranged bearing positions are all provided with crankshafts connected to the power unit, and each crankshaft passes through two cycloidal wheels. hole on the top. The robot RV reducer with this structure first transmits the power device (sun gear) to the three crank shafts (planet gears) at the same time, the crank shaft drives the two cycloidal wheels to run, and the cycloidal wheels transmit the power to the pin gear h...
