Abstract
The utility model provides a sliding bearing for cone crushers. The sliding bearing comprises a bearing body with round bearing holes and a radial oil groove and an axial oil groove are disposed inside the round bearing holes along the circumferential walls. The sliding bearing is characterized in that at least two additional radial oil grooves are arranged inside the round bearing holes along the circumferential walls. The sufficient lubrication can be achieved through installing a plurality of radial oil grooves along the circumferential walls on the sliding bearing of the cone crushers; therefore, the bearing capacity of the bearings is improved, bearing overheating and burning out because of the insufficient lubrication and the increasing friction owing to overloading can be avoided, and the problems of materials blocking and jamming because of overloading are solved.
Description
Technical field
The utility model relates to a kind of sliding bearing, and a kind of gyratory crusher sliding bearing particularly belongs to mechanical lubrication design and manufacturing technology field.
Background technique
Gyratory crusher is widely used in the industries such as metallurgy, mine, can be used for ore, the rock of broken medium and medium above intensity.But, in the actual production using process, main eccentric sliding bearing or horizontal slip bearing often can occur by the situation of scaling loss, cause the normal production order to be upset because of maintain and replace.In addition, in case the ore processing inlet amount is bigger than normal, main frame will produce putty because of bearing fault, and when particularly ore dampness was larger, putty, jam phenomenon were particularly outstanding.For addressing the above problem the operating overload protective system of having to, this system in case start will make the bulk mineral aggregate be forced to automatic discharge undressed during to desired granularity, thus can not reach regulation the ore grain size requirement.Therefore be necessary prior art is improved.
Summary of the invention
Overheated damage easily occurs for solving existing gyratory crusher sliding bearing when the normal operation, and load carried causes the problem of disintegrator putty, jam when excessive, the utility model provides a kind of gyratory crusher sliding bearing.
The utility model is completed by following technical proposal: a kind of gyratory crusher sliding bearing, comprise the bearing support of establishing the circular shaft hole in it, be provided with radially oil groove and an axial oil groove along peripheral wall in the circular shaft hole, it is characterized in that setting up at least two radially oil grooves along peripheral wall in the circular shaft hole, so that bearing passes through many radially oil groove increase lubricant oil oil inlet quantities when operation, thereby the generation of the bearing running hot of avoiding and overload.
The utlity model has following advantages and effect: adopt such scheme, by on the gyratory crusher sliding bearing, along peripheral wall, many radially oil grooves are set, reaching the purpose of sufficient lubrication, thereby avoid lubricated insufficient bearing running hot problem that causes, with under the sufficient lubrication of lubricant oil, improve the bearing capacity of bearing, avoid the overheated and bearing burnt that causes because of insufficient lubrication, and overload and increasing friction force, and solved putty, jam problem because overload causes.Be a desirable disintegrator bearing in fact.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As Fig. 1, the gyratory crusher sliding bearing that the utility model provides, comprise the bearing support 2 of establishing circular shaft hole 1 in it, circular shaft hole 1 is interior is provided with radially oil groove 4 and an axial oil groove 3 along peripheral wall, establish oilhole 6 on axial oil groove 3, oilhole 6 is connected with fuel supply line, so that lubricant oil to be provided, circular shaft hole 1 is interior sets up two radially oil grooves 5 along peripheral wall, so that bearing is the further reinforcement lubricant oil oil inlet quantity of radially oil groove 5 by setting up when operation, thereby avoid bearing burnt and overheated, and overload and increasing friction force.
