Production and diagnostic method of the rolling bearing trouble of the locomotive


26th February 2010 Bearing Technology 0 Comments
A foreword The bearing as the main part of the locomotive, especially draw the electrical machinery, axle case bearing, function its play a very important role in transporting safely, run at the online locomotive, once the bearing breaks down, will cause the permutation train not to be be operated, will stop up the straight line of transportation, especially the passenger train breaks down, the negative effect caused is bigger, at the same time once the bearing of the locomotive breaks down, it is very difficult to the emergent repairment of the locomotive, so prevent and reduce the emergence ...

The surface of the bearing rubs and pares reason and analysis which presents the defect


26th February 2010 Bearing Technology 0 Comments
The bearing rubs the processing course, its surface of job is rubed and pared through the rotation emery wheel of the high speed, so rub and does not operate and adjust the apparatus according to the homework guide book while paring, know the surface of bearing job and present all sorts of defects, so that influence the whole quality of the bearing. Bearing accurate rub, sharpen, because of coarse to expect very much, job surface present, rub, sharpen trace, can observe surface their rub, have the following aspects to sharpen the trace mainly with naked eye often. Display and cross the helix ...

Compare with measuring to analyze outside China: The hub bearing seals the structure


26th February 2010 Bearing Technology 0 Comments
It is that enterprises promote the technological progress to compare with the analytic approach, improve a shortcut of product quality, through an analysis of similar sample outside China, comparison, obtained a lot of technology of the other side, information of quality, draw lessons from foreign products advantage and characteristic in technology such as the structure, is used by me, overcome disparity and deficiency in product quality and engineering level of this enterprise, improve, in order to catch up with and surpass the advanced stage outside China, strengthen the competitive power ...

The single stage form sucks the transformation of the lubricated way of the bearing of the centrifugal pump


26th February 2010 Bearing Technology 0 Comments
Content summary: The IS series single stage form sucks the centrifugal pump, because of designing the reason, the rolling bearing that the centrifugal pump uses is lubricated with the engine oil, it is very serious to move and seal letting out, the peace and steadiness of threatening the apparatus runs, I am in a few years' work, seal, carry on a numerous one to be little to make a change to make sure result with little leather to the intersection of bearing and case. But let out the problem and has not solved completely, and then change the engine oil to lubricate and lubricate as ...

The production characteristic of the rolling bearing determines the characteristic of its process


26th February 2010 Bearing Technology 0 Comments
The production characteristic of the rolling bearing, it is determined that its process has the following three major characteristics: 1.In the specialized bearing part is processed, adopt the dedicated device of the bearing in a large amount. If the steel ball processes and adopts apparatuses such as the ball rubing machine, grinding machine,etc.. The specialized characteristic still reflects such as the steel ball company specializing in steel ball, miniature bearing factory specializing in miniature bearing,etc. in the production of the part of the bearing. 2.The specialization of ...

Classification of the invalid basic shape of the bearing


26th February 2010 Bearing Technology 0 Comments
1.Adhere to and abrade and fail with the grit It is one of the most common failure modes of surface of all kinds of bearings. Relative sliding friction causes the metal constant losses of its surface to be called slipping and rubing decreasing between the parts of the bearing. The lasting abrasion will make part size and shape change, the bearing cooperates with the interval to increase, the superficial topography of the work deteriorates, thus lose and rotate the precision, make the bearing unable to work normally. Slipping the abrasion form can be divided into grit to abrade, adhere to ...

Installation, cooperation and adjusting the method of the high-speed bearing


26th February 2010 Bearing Technology 0 Comments
The installation, cooperation and adjusting the method of the high-speed bearing: First. Cooperation and backlash of the high-speed bearing Because the high-speed bearing not only should be according to the high-accuracy bearing requirement, but also according to the high-temperature bearing requirement, so as considering it cooperates and backlash, should take two following points into account: 1 . Because size change and hardness change that the normal atmospheric temperature causes while rising to the high temperature; 2 . Because the strength that the centrifugal force causes is change ...

Choose and use the attentive matters of the bearing correctly


26th February 2010 Bearing Technology 0 Comments
With the progress and development of the society, it is used widely in production and life to be mechanized. The bearing, as an indispensable part in machinery, its range used will be wider and wider too, because so long as there are places to rotate to be used the bearing. The bearing mainly plays a role in supporting and reduced and gritted in machinery, so precision, noise of the bearing,etc. concern mechanical use and life-span directly. But business personnel always often can run into, even use best bearing or it imports the intersection of bearing and efficiency its to be high by some ...

The bearing that is made sand machine avoids the method to generate heat


26th February 2010 Bearing Technology 0 Comments
In the field of mining industry, make the sand machine and is widely applied to rubing the first period of craft of ore, it can produce a large number of powder ores, reduce expensive rubing the ore load. In the mechanical equipment, it is excellent to rely on the medium steel ball, steeling, gravel Impact and rubing and shelling function, make the granularity of the ore further diminish with ore, until grinding into the homework of powder. The purpose is to make to make up useful mineral and gangue mineral of the ore to achieve maximum dissociation, in order to offer on the granularity ...
