Embodiment Construction

[0021] see in conjunction Figure 1 to Figure 2 As shown, according to an embodiment of the present invention, a tapered roller bearing is provided, including an inner ring 1, an outer ring 2, and a tapered roller 3 between the inner ring 1 and the outer ring 2, and the outer ring 1 The outer peripheral wall of the ring 2 is configured with a first thread 21 (such as an external thread), and the outer ring 2 can pass through the first thread 21 to cooperate with the second thread on the wall of the mounting hole (such as an external thread). internal thread) to form a screw-in connection. In this technical solution, the installation and positioning of the tapered roller bearing can be realized so as to achieve the positioning function jointly realized by the limiting boss, the limiting retaining ring and the retaining ring groove in the prior art, which simplifies the assembly structure and reduces the Difficulty in installation, it is also possible to use the linear relation...

Abstract

The invention provides a tapered roller bearing, an RV speed reducer and a robot. The tapered roller bearing comprises an inner ring, an outer ring and a tapered roller located between the inner ring and the outer ring, a first thread is constructed on the outer circumferential wall of the outer ring, and the outer ring can be in screwed connection with a second thread on the hole wall of a mounting hole matched with the outer ring through the first thread. The tapered roller bearing can be mounted and positioned, so that the positioning effect jointly realized by a limiting boss, a limiting check ring and a check ring groove in the prior art is realized, the assembly structure is simplified, the mounting difficulty is reduced, in addition, the linear relation between the external torque and the generated axial thrust in the thread screwing process of the first thread and the second thread can be utilized, the pre-tightening force of the bearing is accurately controlled through screwing, and the pre-tightening precision of the bearing is improved.

Description

technical field [0001] The invention belongs to the technical field of reducer manufacturing, and in particular relates to a tapered roller bearing, an RV reducer and a robot. Background technique [0002] The RV reducer is mainly composed of one-stage planetary gear transmission and two-stage cycloidal pinwheel transmission, which is a new type of cycloidal pinwheel planetary transmission reducer. RV reducers are mostly used in the joint positions of industrial robots. This puts forward high transmission accuracy, high rigidity, high transmission efficiency, strong impact resistance, and compact structure for RV reducers. These requirements affect the processing accuracy of RV reducer parts. and assembly accuracy put forward higher requirements. The crankshaft is the core component of the RV reducer, which is responsible for the power output of the primary transmission and the power input of the secondary transmission. The performance of the bearing supporting the operatio...
