Embodiment Construction

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

[0016] Bearing outer ring is made up of left end outer ring gear 6, right end outer ring gear 9 and bearing outer ring raceway 3, and is fixed together or as a whole.

[0017] Planetary roller is made up of left-end planetary pinion 5, right-end planetary pinion 8 and middle roller 2 and is fixed together or as a whole.

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

[0019] It is characterized in that a set of planetary gears work together at both ends of the planetary roller bearing, so that the two sets of planetary gears roll and mesh at the same time when the bearing is working, and at the same time, the roller 2 of the planetary bearing, the raceway 1 of the inner ring of the bear...

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 mechanical 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 moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, rolling bearings are generally composed of four parts: outer ring, inner ring, rolling elements and cage. [0003] The cage is one of the main parts of the bearing, and its main functions are: 1. Separate and evacuate the rotating body, prevent direct contact with the rolling elements, and minimize friction and heat generation; 2. Guide the rolling bodies to run on the raceway; 3. Provide lubrication space; 4. Orient the rotating body and reduce f...
