Abstract
The invention discloses an eccentric cover part of a conic crusher, which comprises a conic bush that is arranged at the inner side and an eccentric cover that is arranged outside; and the conic bush is made of nylon. The invention greatly decreases the fricative coefficient of the conic bush by adopting nylon to make the conic cover; and the light weight of nylon causes small frication in working, thus not generating lots of heat, avoiding cover burning, not consuming excessive power and greatly reducing manufacturing cost.
Description
Technical field
The present invention relates to the eccentric cover section in a kind of gyratory crusher.
Background technology
In existing gyratory crusher, the awl lining of gyratory crusher drives crushing head portion pendulum and revolves, and it is stressed very big therefore to bore lining, and the material that needs higher-strength is made.Awl lining in the past adopts cast copper to make, because coefficient of friction is bigger, and the quality of copper itself is also very big, the awl lining can produce very big heat because of friction at work, and the cover phenomenon appears burning easily, and also to consume more power simultaneously, use cost is higher.
Summary of the invention
Technical problem to be solved by this invention provides the eccentric cover section in a kind of gyratory crusher, can have less coefficient of friction and less quality, and is more durable, and reduces cost.
For solving the problems of the technologies described above, the technical scheme of the eccentric cover section in the gyratory crusher of the present invention is to comprise being positioned at inboard awl lining and the eccentric bushing that is positioned at the outside that described awl lining is made with nylon.
Be that described awl lining is fixed together by epoxy resin and described eccentric bushing as a further improvement on the present invention.
The present invention makes the awl lining by adopting nylon material, reduced the coefficient of friction of awl lining greatly, and the quality of nylon is less, friction in the work is also little, thereby can not produce very big heat, has avoided burning the generation of cover phenomenon, and can not consume too much power, greatly reduce cost.
Description of drawings
The present invention is further detailed explanation below in conjunction with drawings and Examples:
Accompanying drawing is the section of structure of the eccentric cover section in the gyratory crusher of the present invention.
Reference numeral is among the figure, 1. eccentric bushing; 2. awl lining; 3. epoxy resin.
The specific embodiment
The structure of the eccentric cover section in the gyratory crusher of the present invention can comprise the eccentric bushing 1 that is positioned at inboard awl lining 2 and is positioned at the outside referring to shown in the accompanying drawing, and described awl lining 1 usefulness nylon is made.Described awl lining 2 is fixed together by epoxy resin 3 and described eccentric bushing 1.
The present invention uses nylon to be made into awl lining 2, is contained in the eccentric bushing 1, and the two bonds with epoxy resin 3, because but the nylon centrifugal casting forming as long as process slightly, just can reach matching requirements, reduced process time, because coefficient of friction is littler than cast copper material,, be difficult for burning cover so the heat that produces also reduces greatly, be more than 2 times of cast copper service life in theory, and cost of manufacture is 1/3 of a cast copper, and the also decline greatly of its unused power, can improve the treating capacity of circular cone indirectly.
The present invention makes the awl lining by adopting nylon material, reduced the coefficient of friction of awl lining greatly, and the quality of nylon is less, friction in the work is also little, thereby can not produce very big heat, has avoided burning the generation of cover phenomenon, and can not consume too much power, greatly reduce cost.
Claims (2)
1. the eccentric cover section in the gyratory crusher comprises the eccentric bushing that is positioned at inboard awl lining and is positioned at the outside, it is characterized in that described awl lining is made with nylon.
2. the eccentric cover section in the gyratory crusher according to claim 1 is characterized in that, described awl lining is fixed together by epoxy resin and described eccentric bushing.
