Abstract
The utility model relates to bearing type on shearer walk gear, comprise inner ring, the rolling element having some contact-types to arrange in the space surrounded inside inner ring and walking wheel of coal cutter gear, with centre rib inside inner ring, form an annular groove in the middle part of rolling element radial surface, the centre rib of inner ring embeds in the annular groove of rolling element.Being provided with Sealing the utility model inside inner ring by cancelling retainer and outer ring, increasing its bearing capacity, and the object that realization increases the service life.By adopting two row rolling element designs, ensure that the stability of road wheel.By improving sealing means, simplifying sealing configuration, making bearing be convenient to dismounting, shortening the duration of installation and maintenance.
Description
Technical field
The utility model relates to bearing, particularly bearing type on shearer walk gear.
Background technique
Chainless hauled shearer, at present most walking manner adopting the engagement of cycloid wheel pin rail, its road wheel is many wheel constructions, and core need install bearing additional.Traditional bearing is provided with inner ring and outer ring, and mostly need be furnished with special bearing at bearing face with the use of this bearing of retainer and fix and seal arrangement, its structure relative complex, and sealing effect is undesirable, and because of by spatial constraints, load-carrying ability is limited.Due to the carrying capacity that day by day increases with to bearing requirements at the higher level in working life, original bearing structure can not meet the demand of production status, and lifting capacity and the working life of how to improve bearing become urgent problem.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of bearing type on shearer walk gear of high loadability.
For solving above technical problem, the utility model improves on the basis of existing bearing structure.A kind of bearing type on shearer walk gear of the utility model, comprise inner ring, the rolling element having some contact-types to arrange in the space surrounded inside inner ring and walking wheel of coal cutter gear, with centre rib inside inner ring, form an annular groove in the middle part of rolling element radial surface, the centre rib of inner ring embeds in the annular groove of rolling element.
The utility model bearing, without retainer, completely fills rolling element, is guided voluntarily during work by rolling element.Eliminate outer ring, rolling element to act directly on outside bearing inner race and inside coal winning machine gear.Rolling element is divided into two sections by the annular groove in the middle part of rolling element, forms two row rolling elements, and two row rolling elements operationally restrict mutually, ensure that the stability of road wheel.Relative to the bearing of same size, increase rolling element diameter, add rolling element quantity, the rolling element quantity that carrying effect is played in loading zone is many, and bearing capacity is high, ensure that startability and the stability of walking wheel of coal cutter simultaneously.
Be provided with Sealing inside inner ring, this sealing configuration is more simple, and dismounting is also more convenient.
The utility model is not high for walking wheel of coal cutter rotating speed, the improvement that the feature that load is larger is done.Breaching conventional bearings design concept, by cancelling retainer and outer ring, increasing its bearing capacity, and the object that realization increases the service life.By adopting two row rolling element designs, ensure that the stability of road wheel.By improving sealing means, simplifying sealing configuration, making bearing be convenient to dismounting, shortening the duration of installation and maintenance.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model bearing type on shearer walk gear.
In figure, 1-inner ring, 2-walking wheel of coal cutter gear, 3-rolling element, 4-centre rib.
Embodiment
In order to make those skilled in the art better understand the utility model, below in conjunction with accompanying drawing, explanation clear, complete is further done to the utility model.
Bearing type on shearer walk gear shown in Fig. 1, comprises inner ring 1, the rolling element 3 having some contact-types to arrange in the space surrounded inside inner ring 1 with walking wheel of coal cutter gear 2.The axial length of rolling element 3 is less than the axial length in the space surrounded inside inner ring 1 and walking wheel of coal cutter gear 2.The utility model bearing, without retainer, completely fills rolling element, is guided voluntarily during work by rolling element.Eliminate outer ring, rolling element to act directly on outside bearing inner race and inside coal winning machine gear.
With centre rib 4 inside inner ring 1, an annular groove is formed in the middle part of rolling element 3 radial surface, arbitrary rolling element 3 is divided into two newel posts by annular groove, the rolling element of all full dresses forms the less rolling element of two row axial lengths in space, and the centre rib 4 of inner ring 1 embeds in the annular groove of rolling element.Two row rolling elements operationally restrict mutually, ensure that the stability of road wheel.
Be provided with Sealing and oilhole inside inner ring 1, ensure that in bearing bore, lubricant oil normally uses.
The claimed scope of the utility model is not limited to above embodiment; to those skilled in the art; the utility model can have various deformation and change, all in design of the present utility model and any amendment, the improvement done within principle be equal to replacement and all should be included within protection domain of the present utility model.
Claims (2)
1. a bearing type on shearer walk gear, comprise inner ring (1), it is characterized in that: the rolling element (3) having some contact-types to arrange in the space that inner ring (1) and walking wheel of coal cutter gear (2) inner side surround, inner ring (1) inner side is with centre rib (4), form an annular groove in the middle part of rolling element (3) radial surface, the centre rib (4) of inner ring (1) embeds in the annular groove of rolling element.
2. bearing type on shearer walk gear according to claim 1, is characterized in that: inner ring (1) inner side is provided with Sealing.
