Abstract

The invention relates to a three-row cylinder roller bearing for a main bearing of a shield machine. The inner tooth type three-row cylinder roller bearing with unequal diameter is provided with a sealing system, can bear axial/radial loads and tilting moment at the same time, and has the characteristics of good reliability and high bearing capacity. The characteristics of the three-row cylinder roller bearing in the invention are as follows: the convexity shape and value of a cylindrical roller bus are optimized; as an integrated retaining rack is adopted, an inseparable roller and a retaining rack assembly are formed; meanwhile, a lubricating system of the main bearing is designed in an optimized manner, minimum flow can take away maximum heat, the lubrication is improved, and the service life of the bearing is prolonged.

Description

The three-row cylinder roller bearing that is used for the shield machine main bearing
Technical field
The present invention relates to a kind of three-row cylinder roller bearing that is used for the shield machine main bearing.
Background technique
Main bearing is the critical component of shield machine during shield construction, its working environment complexity, bear axially simultaneously, radial load and tilting moment, reliability requirement reaches 100%, therefore all to carry out well-designed to each link of main bearing and research, reach high reliability, high bearing capacity, long-life requirement.
Summary of the invention
The objective of the invention is: a kind of high reliability, high bearing capacity, long-life three-row cylinder roller bearing that is used for the shield machine main bearing are provided.
The three-row cylinder roller bearing that is used for the shield machine main bearing comprises low thrust roller 1, radial roller 2, high thrust roller 3, retainer 4, first lubrication system 5, second lubrication system 6, outer ring 7, sealing system 8 and band ring gear 9.Wherein retainer 4 is the integral type retainer, low thrust roller 1, radial roller 2 and high thrust roller 3 are contained in respectively in the retainer 4, constitute the retainer roller assembly, the retainer roller assembly is contained in the band ring gear 9,7 sections and external diameter surface are respectively equipped with three and ranked first the lubrication system 5 and second lubrication system 6 in the outer ring, first lubrication system 5 and second lubrication system 6 communicate with the retainer roller assembly, and 8 pairs of outer rings of sealing system 7 and band ring gear 9 seal.
In the bearing working process, lubrication oil circulation in first lubrication system 5 and second lubrication system 6 flows, low thrust roller 1, radial roller 2, high thrust roller 3, outer ring 7 and band ring gear 9 are lubricated and lower the temperature, and 8 pairs of bearings of sealing system prevent dust and seal.
Low thrust roller 1 retainer assembly of the present invention bears augmented thrust load, high thrust roller 3 retainer assemblies bear main thrust load and the radial roller assembly bears radial load, reaches that bearing can bear axially simultaneously, radial load and tilting moment.
The invention has the beneficial effects as follows:
1, the waney roller bearing of internal gear type three row that carries sealing system can bear simultaneously axially, radial load and tilting moment, reliability height, bearing capacity height;
2, cylindrical roller bus protuberance shape and numerical value have been optimized;
3, integral type retainer forms inseparable roller and retainer assembly;
4, optimal design the main bearing lubrication system, minimum discharge is taken away maximum heat, improves lubricatedly, improves bearing working life.
