The roller seat is conveyor parts of the heart, it is waterproof and dustproof, particularly for semi mobile objects (mud) pollution sealing performance, both ends of the bearing position precision, cylindrical radial runout, rotary inertia, resistance and noise when running, anti corrosion, wear resistance, can have a direct influence to the operation of conveyor accessories. Take no overall plan for a fundamental transformation of technological innovation to roller effect is very little. Such as increasing the thickness of the pipe wall, in order to improve the wear resistance of roller. This method is not only the seal does not solve the problem, but also increase the moment of inertia of roller bearing, and clamping tape will cause premature failure of serious wear and energy loss, noise pollution and potential accidents.
In order to make the comprehensive performance of roller to achieve the desired requirements, change the traditional roller sealing structure, reduce the weight of the rotary part, the main causes of the premature failure of traditional supporting roller is a labyrinth sealing gap are exposed on the outside, roller operation work, water spraying and dust slime easily along the gap drill into the labyrinth seal structure. Just go to the first line of pollutants will be a maze, extended to the inside, bearing soon be blocked.
Roller roller accessories is the premise to guarantee the normal operation of the equipment, roller parts quality, quality is stable operation of great influence and role, and the roller can keep in good condition and will greatly affect the efficiency so that any conveyor, a small roller parts parts will be the results of large conveyors generate both positive and negative effects of more or less, but in order not to let the roller parts have a negative infection on the conveyor, the need for users to carry out maintenance and maintenance of the nuanced. For the maintenance of roller parts can be very simple, can also be very complicated, because the roller parts are composed of zero small parts of a variety of large and small maintenance, do more in place better, but it is also more trouble. However, in order to make full use of roller parts, and maintain a good performance for a long time, have to maintain in-depth. Maintenance must be maintained on a regular basis, the various parts of the overall maintenance, but also to stop the operation of machinery. For the removal process of the roller parts, can be checked by checking its size, rotation accuracy, wear and tear to determine whether it can continue to put into use.
Roller parts plays in conveying system in the role, first of all, we need to know that the roller is made of many individual parts together, which are collectively referred to as the roller parts, including: roller bearing stamping, roller bearings, roller, roller frame, spacer sleeves, hooks, cast steel joint rake, cylindrical pin, roller and shaft circlip ring, which plays an important role in these and roller bearing stamping and roller bearings, but remove these two roller parts and other outside support also plays an important role in the production. The machine, no matter what a small part of problems, will lead the whole work is not working.
Roller accessories can be used in the roller in the play an important role and the cost, can help the use and maintenance of the roller, to help users in the maintenance of rollers play an important role and cost.
The production and processing precision of the roller accessories is the concentricity of the two holes in the shell and the supporting roller and the machining precision of the axial dimension of each part.
If the concentricity is too poor, will cause the bearing bite death, growth resistance, low utilization of life; if the axial size deviation of parts is too large, will form a large axial gap, resulting in axial crushing, lubrication and sealing; if the placement quality is not good, will produce deviation, bite card, greatly increased wear. Low roller service life.
How to arrange the roller, roller group plan appropriate spacing, to eliminate the use of roller support number, the low price, the elimination of investment, operations and maintenance costs, improve economic efficiency, the processing technology of the roller is one of the important aspects.a |
