Abstract
The utility model relates to a deep groove ball bearing guided by a steel ball, which belongs to the field of bearings. Compared with the prior art, the sealed four-row cylinder bearing has the following outstanding advantages and positive effects: a sealed cover is additionally arranged on the bearing, so that impurities such as outer water, scale cinder and the like can not enter the inner part of the bearing, excellent lubrication in the bearing can be ensured, and the service life of the bearing is prolonged. Therefore, the frequency of disassembling the roller for replacing the bearing can be reduced, the production efficiency is improved greatly, and the economic benefits are improved.
Description
Technical field
The utility model relates to a kind of deep groove ball bearing of steel ball guiding, and it belongs to field of bearings.
Background technique
Along with the high speed development of the continuous evolution of human civilization and science and technology, bearing industry is from small and weak starting, difficult foundation, keen competition, tortuous development, by several wife and children factory in the past develop into now spread all over the world, a year sales volume volume reaches 30,000,000,000 dollars scale, obtained astonishing achievements.Usually press the difference of rolling element kind in the bearing, it is divided into ball bearing and roller bearing, and be divided into radial bearing and thrust-bearing by the main action direction that bearing can bear load.The four row cylindrical bearings that generally use are used on the milling equipment that need bear heavy load mostly at present, in the process of hot-rolled profile, profile shapes and sheet material, need to use the water cooling stocking, water, scale and other impurity inevitably just enter bearing inside like this, destroy the lubricant medium of bearing inside, make bearing shift to an earlier date fatigue wear and damage, reduce the working life of bearing.
Summary of the invention
Defective in view of the prior art existence, the purpose of this utility model is that a kind of sealed four-row cylindrical bearing will be provided, it adopts the structure that has sealing cover, reach other impurity such as preventing outside water and scale and can not enter bearing inside, guarantee the good lubrication of bearing inside, improve the purpose in the working life of bearing.
For achieving the above object, a kind of sealed four-row cylindrical bearing of the technical solution that the utility model adopted, it comprises outer ring, retainer, roller and inner ring, it also comprises: sealing cover, be provided with outer ring spacer between two outer rings, the centre of outer ring and inner ring is provided with two row retainers, be provided with central diaphragm between the two row retainers, roller is installed in the space of retainer inside and contacts with the raceway of outer ring and inner ring respectively, be provided with sealing cover between outer ring and the inner ring, inner ring cooperates with axle, outer ring and cooperate with shell.
The utility model compared with prior art, have following outstanding advantage and good effect: it adds sealing cover on bearing, make other impurity such as outside water and scale can not enter bearing inside, guaranteed the good lubrication of bearing inside, make the working life of improving bearing.Tear the frequency that roller unloads roller open thereby reduced, improved manufacturing efficiency greatly, improved economic benefit to changing bearing.
