Problems solved by technology

In addition, when the working environment of industrial robots is relatively complex, the RV reducer will occasionally encounter impact torque
These irregular and overloaded torques finally act on the tapered roller bearings on the eccentric shaft, causing wear of the tapered roller bearings, and their service life is much shorter than that of other components inside the RV reducer
Therefore, the service life of the tapered roller bearing is basically the service life of the RV reducer, which restricts the improvement of the service life of the RV reducer.

Embodiment Construction

[0027] An RV reducer with a high-performance structure, including a first-stage planetary reduction mechanism 1, a second-stage cycloidal reduction mechanism 2, and an angular contact bearing 7. The planetary gear 3 of the first-stage planetary reduction mechanism meshes with the central gear 5 at one end of the input shaft 4 , the above-mentioned two-stage deceleration mechanism is connected through the eccentric shaft 5, and there are three eccentric shafts 6, and the three eccentric shafts are evenly distributed on the circumference at intervals of 120 degrees; the angular contact ball bearing 7 is a one-piece type, that is, the outer ring is independent, and the inner ring and the output disk Frame 8 integrated structure.

[0028] The planetary gear is a structural form embedded in the reducer, or a structural form exposed outside the reducer.

[0029] The input shaft is installed from the left side of the RV reducer (that is, the side close to the motor), or from the righ...

Abstract

The invention discloses a high-performance structure RV reduction machine. The high-performance structure RV reduction machine comprises a one-level planet speed reducing mechanism, a two-level cycloid speed reducing mechanism and an angular contact bearing. A planet gear of the one-level planet speed reducing mechanism is meshed with a center gear at one end of an input shaft. The one-level planet speed reducing mechanism and the two-level cycloid speed reducing mechanism are connected through three eccentric shafts, and the three eccentric shafts are evenly distributed on a circumference at 120-degree intervals. The angular contact bearing is in a connection shape, that is, an outer ring is independent, and an inner ring and an output disk rack are of an integrated structure. The high-performance structure RV reduction machine is reasonable in structure and long in service life.

Description

technical field [0001] The invention relates to an RV speed reducer. Background technique [0002] The RV reducer has the characteristics of high precision, small size and high load torque, and is widely used in the field of industrial robots. figure 1 It is a simplified structural diagram of the most widely used traditional RV reducer (models 6E, 20E, 40E or similar at home and abroad). The RV reducer consists of a two-stage reduction mechanism. One end of the input shaft is connected to the motor, and the sun gear at the other end meshes with the planetary gear to form the first-stage planetary reduction mechanism. The cycloidal wheel, needle roller and pin gear housing constitute the second-stage cycloidal reduction mechanism. The two-stage reduction mechanism is connected by two eccentric shafts to transmit speed and torque. This small type of RV reducer uses two eccentric shafts, and each eccentric shaft has two tapered roller bearings, which are responsible for tra...
