Embodiment Construction

[0017] In order to make the structure and function of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0018] See attached figure 1 , a highly integrated double-axis bearing unit, the double-axis bearing includes a first inner ring 12, an outer ring 14, a rotating steel ball, a cage 13, a second inner ring 5, a swinging steel ball and an engaging ring gear 11; The first inner ring 12 is composed of a lower part, an upper part and a supporting part from bottom to top, and a cage 13 is installed between the outer ring 14 and the lower part of the first inner ring, and the cage 13 keeps the rotating steel balls between the outer ring and the first inner ring. Between the lower part of the first inner ring, the first bearing structure is formed, and the axis of this part is the first axis A; the second inne...

Abstract

The invention belongs to the technical field of bearing equipment manufacturing, and particularly relates to a high-integrated double-axis bearing unit. The end face of a double-axis bearing is provided with meshing teeth in the circumferential direction, one side of the double-axis bearing is provided with a paired gear ring matched with the meshing teeth, an included angle is formed between theend face of the dual-axis bearing and the paired gear ring, and the meshing teeth of the double-axis bearing are meshed with the paired gear ring at the intersection of the included angle. By means ofthe high-integrated double-axis bearing unit, a circular bevel gear structure design is integrated to a bearing structure to be used for limiting the circular motion of the meshing gear ring, the rotation stopping effect is achieved, a working mode that a plunger piston does cyclical movement up and down while the meshing gear ring is static in the peripheral direction is achieved, the bearing structure is simplified, and meanwhile, functional operation of the entire bearing unit is ensured.

Description

technical field [0001] The invention belongs to the technical field of bearing equipment manufacturing, and in particular relates to a highly integrated double-shaft bearing unit. Background technique [0002] Aviation hydraulic pumps or other similar hydraulic pump systems have periodic circumferential and axial compound motions, so the bearings used to support the hydraulic pump rotor are required to be compact and lightweight. At present, the bearings of aviation hydraulic pumps and other related accessories are assembled and used independently, and the structure is bloated and complicated. Moreover, this part has a relatively large axial load and a high rotational speed, which requires the support bearing of this part to have the characteristics of compact structure, stable operation, strong bearing capacity, and high reliability, and at the same time meet the periodic axial and circumferential directions of the main engine. compound exercise. Contents of the inventio...
