Abstract
A retainer device for a slewing ring bearing solves the difficult problems that a bearing retainer has a limited dimension, large friction force and complicated remodeling, improves the mechanical strength, the wearing resistance and the stability so as to ensure excellent guidance and adapt to the working conditions with high rotational speed and low noise, and meanwhile reduces the manufacturing cost and improves the production efficiency. The retainer device is composed of a retainer base ring, first blocks and second blocks, wherein a circle of partitions are uniformly distributed on the double-layered annular retainer base ring, girder-shaped grooves are reserved on the two sides of the partitions, and the first girder-shaped blocks are arranged in the grooves; and another circle of partitions are arranged on the retainer base ring, girder-shaped grooves are reserved on the partitions on the inner-diameter side, the second girder-shaped blocks are arranged in the grooves, and the second blocks and the first blocks are alternatively arranged at intervals. The girder-shaped grooves of the retainer base ring are wedged grooves. The tail ends of the first blocks and the second blocks are wedged. The retainer device has the advantages of wide application range, easiness in modification, and convenience in operation; and the serviceability is enhanced, and the service life is prolonged.
Description
Technical field
The utility model relates to the retainer device, especially a kind of retainer device of pivoting support bearing.
Background technique
Retainer plays crucial effects in the use work of bearing and pivoting support, its quality even determining bearing can accomplish design usability and the life-span, and then limiting the performance of main frame.Along with continually developing of large-scale, super-huge and special bearing used and being widely used of super sized type heavy duty pivoting support, also more and more stricter to the requirement of crucial annex retainer.
Mechanical property such as intensity and wear resistance are the key performances of retainer material with stability, and geometrical shape that retainer is correct and guidance capability are the bases that bearing is finished the work.Along with the appearance of new material such as nylon etc., solved the application requirements of part occasion.But in the higher occasion of temperature; And under the applying working condition of extra long life, super large load; The high and low temperature resistance of common nylon spare and self intensity can't have been kept stable performance of retainer and shape, and damage will had a greatly reduced quality even occur to the usability of bearing this moment.This type of occasion, considered are used the metal retainer, and material commonly used has aluminium matter, steel, copper etc.In practical application; Cast aluminium material cost is low; But intensity difference, steel intensity is high, the good but serious wear of geometrical shape making; And all kinds of copper holders are showing excellent performance in increasing crucial occasion, but but its expensive price and less size production range have limited its extensive use.
General retainer is divided into integral cage and segmented retainer, and general segmented cost is lower in application, and the integral cage form can be guaranteed good guiding property, adapts to the applying working condition of high rotating speed, low noise.But if copper cage has this requirement; Then but the expense of centrifugal pressure casting height and production size are less; So can't satisfy the rotating requirement of heavy duty under several meters size easily, like the crucial bearing of special occasions such as mainshaft bearing of wind-driven generator, cutter head of shield machine bearing.Expensive cost and size restrictions had both increased manufacture cost and risk, had also suppressed the development of a whole set of bearing and even main frame.
At this moment, the steel of employing retainer is arranged also,, make it that accurately geometrical shape, good guiding performance arranged through machining.But there is speed difference between retainer and the revolution lasso; Close material will cause serious wearing and tearing; Especially this retainer will face rapid, the inefficacy fast of wearing and tearing when high rotating speed turns round continuously; Lubricated abundance reduces guide performance, also can cause a series of problems such as noise is big, heating value is big, even often also can't guarantee long-time effectively work.Therefore, the welding copper billet is also arranged on the steel retainer after the machining of appearing to reduce friction.But the welding performance of copper and steel is bad, has not only increased technology difficulty, has also increased the application risk of welding quality, comes off easily.Usually because of the performance impact of retainer the combination property of a whole set of bearing, in case the loss that goes wrong is serious.
In view of the foregoing, the retainer of bearing needs to improve.
The model utility content
The purpose of the utility model is in order to overcome deficiency of the prior art; A kind of retainer device of pivoting support bearing is provided; Solved the difficult problem that retainer is size-constrained, frictional force big, remodeling is loaded down with trivial details; Improve mechanical strength, wear resistance, stability, guaranteed good guiding property and adapt to the operating mode of high rotating speed, low noise, reduced cost of production simultaneously; Improved manufacturing efficiency.
The utility model adopts following technological scheme to achieve these goals: a kind of retainer device of pivoting support bearing is by retainer Ji Quan, the first heap piece, and the second heap piece constitutes; The retainer Ji Quan of double-layer circular ring shape is uniformly distributed with a circle baffle, and I-shaped groove is reserved in the both sides of baffle, and the I-shaped first heap piece is set in the groove; Retainer Ji Quan is uniformly distributed with a circle baffle, and a side of baffle internal diameter is reserved I-shaped groove, and the I-shaped second heap piece is set in the groove, the second heap piece and the first heap piece cross arrangement separately.
The I-shaped groove of described retainer Ji Quan is the wedge groove.
The rear end of the described first heap piece and the second heap piece is a wedge type block.
The utility model cardinal principle is: retainer Ji Quan goes up and adopts machining to go out the wedge groove; So that coming off of wedge groove Vertical direction do not take place in the heap piece of casting; And process the groove big than the wedge groove area in both sides, make the heap piece of casting all exist spacing in both sides and do not come off.
The beneficial effect of the utility model is: each item advantage that has both kept basic circle; And adhered to the heap piece satisfy to strengthen wear resistance, each item specific (special) requirements such as quiet, and limited the possibility that the heap piece comes off again, evaded the sealing-off risk of conventional base steel circle welding copper billet; And widened application area; Help developing the embedding between other special materials, like all kinds of special types, brand-new materials such as nylon, teflon, so that field is widely widened in the production of retainer and use.Because can be through behind the machining Ji Quan, casting embeds the heap piece again, huge fund input when therefore having reduced cast inblock, and applied widely, easy transformation, easy to operate.And then improve practicability, Economy.
The embedding that the utility model improves fulcrum is applied in outside enhancing retainer bulk strength, the guide performance, and the contact performance of retainer is greatly taken on a new look, and has strengthened usability, has prolonged working life.
