Embodiment Construction

[0015] Planetary roller bearings are mainly composed of bearing outer ring, planetary rollers and bearing inner ring. Planetary roller bearings have at least three planetary rollers.

[0016] The outer ring of the bearing is composed of the outer ring gear 6 at the left end, the outer ring gear 9 at the right end and the bearing outer ring raceway 3, and they are fixed together or as a whole.

[0017] The planetary roller is composed of the planetary pinion 5 at the left end, the planetary pinion 8 at the right end and the roller 2 in the middle and are fixed together or as a whole.

[0018] The bearing inner ring is composed of the left end sun gear 4, the right end sun gear 7 and the bearing inner ring raceway 1 and is fixed together or as a whole.

[0019] It is characterized by a set of planetary gears at both ends of the planetary roller bearing to work together, so that the two sets of planetary gears roll and mesh at the same time when the bearing is working. At the same time, ...

Abstract

The invention discloses a planetary roller bearing, relates to the field of mechanical bearings, in particular to a high-speed precise heavy-duty bearing. Two sets of planetary gears are utilized for replacing an ordinary rolling bearing retainer, and the problems that according to the ordinary bearing retainer, due to the fact that the retainer is rubbed and abraded during high-speed running, a rolling body bounces and deviates from the rolling direction, heating of a bearing is intensified, the load is low, and even the bearing is in failure are solved. The planetary roller bearing is the precise heavy-duty bearing high in rotating speed and efficiency, long in service life and high in stability, the lubricating requirement is lower than that of a conventional bearing, and the maintaining cost is low.

Description

Technical field [0001] The invention relates to a mechanical bearing, especially a high-speed precision heavy-duty bearing. Background technique [0002] Bearings are an important part of contemporary machinery and equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. According to the different friction properties of the moving elements, bearings can be divided into rolling bearings and sliding bearings. The rolling bearing generally consists of four parts: outer ring, inner ring, rolling element and cage. [0003] The cage is one of the main parts of the bearing. The main functions are: 1. Separate and evacuate the rotating body, prevent direct contact with the rolling elements, and reduce friction and heat generation to a minimum; 2. Guide the rolling elements to run on the raceway; 3. Provide lubrication space; 4. Orient the rotating body and eliminate friction. It can b...
