Problems solved by technology

[0002] Chinese single-bar diesel engines have widely used bearings at both ends of the crankshaft instead of bearing bushes for axial and radial support in the past 20 years, and the power of single-cylinder diesel engines has also continued to expand. As a result, the bearings used in the range of cylinder diameters from 100 to 125 are all 6314, 6314 bearings are used on the large cylinder diameter. Due to the changing load of the reciprocating motion of the piston, the 6314 bearings are prematurely damaged, and there are many three-package problems. Inconvenient, poor lubrication

Embodiment Construction

[0008] The specific content of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0009] Such as figure 1 As shown, the special roller bearing for a single-cylinder diesel engine includes: an outer ring 1, an inner ring 2, and a number of cylindrical rollers 4 arranged between the outer ring 1 and the inner ring 2 through a cage 3, and between the cylindrical rollers 4 A mounting cavity 5 is provided between the end outer ring 1 and the inner ring 2 , and chamfers 6 are provided on the four corners of the cylindrical roller 4 .

[0010] The above-mentioned special roller bearings for single-cylinder diesel engines are installed on the rotating shaft, and the lubricating oil enters the chamfer 6 from the installation cavity 5 and the oil filling gap 7 between the outer ring 1 and the inner ring 2. Lubricate.

[0011] The above-mentioned special roller bearings for single-cylinder diesel engines, on...

Abstract

The invention discloses a special roller bearing for a single cylinder diesel. The special roller bearing comprises an outer ring, an inner ring and a plurality of cylindrical rollers arranged between the outer ring and the inner ring by virtue of a retainer, mounting cavities are arranged between the outer ring and the inner ring at two ends of the cylinder rollers, and flip angles are arranged at the four corners of each cylindrical roller. The roller bearing has the advantages that the bearing capacity is constant, the radial bearing capability is improved by more than 90%, the practical use requirement is met in the maximum range, the manufacturing cost is not increased, the use effect is good, zero fault in the three-guarantee period specified by the nation can be achieved, the service life is long, the use range is wide, good benefits are brought to factories, and more importantly, great benefits can be brought to the society.

Description

technical field [0001] The invention relates to a bearing, in particular to a special roller bearing for a single-cylinder diesel engine. Background technique [0002] Chinese single-bar diesel engines have widely used bearings at both ends of the crankshaft instead of bearing bushes for axial and radial support in the past 20 years, and the power of single-cylinder diesel engines has also continued to expand. As a result, the bearings used in the range of cylinder diameters from 100 to 125 are all 6314, 6314 bearings are used on the large cylinder diameter. Due to the changing load of the reciprocating motion of the piston, the 6314 bearings are prematurely damaged, and there are many three-package problems. Inconvenient, poor lubrication effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a special roller bearing for single cylinder diesel engine with long service life. [0004] In order to solve the abov...
