Abstract

The utility model relates to a bearing seat of a jaw crusher, which belongs to a component in the jaw crusher. The existing bearing seat consists of three reinforcing ribs and a bearing seat body, one reinforcing rib is distributed right below a bearing hole, the structure is not firm enough, and the reinforcing ribs can be easily damaged. The bearing seat of the utility model consists of the bearing seat body with bearing holes and the reinforcing ribs. The utility model is characterized in that the reinforcing ribs consist of a No.1 reinforcing rib, a No.2 reinforcing rib, a No.3 reinforcing rib and a No.4 reinforcing rib, all of the No.1 reinforcing rib, the No.2 reinforcing rib, the No.3 reinforcing rib and the No.4 reinforcing rib are fixed on the bearing seat body, and are positioned under a horizontal symmetry line of the bearing holes, the No.1 reinforcing rib and the No.4 reinforcing rib are in symmetry along the center line of the bearing seat body, and the No.2 reinforcing rib and the No.3 reinforcing rib are in symmetry along the center line of the bearing seat body. The utility model has the advantages of firm structure, reasonable design and long service life.

Description

A kind of jaw crusher bearing block

Technical field

The utility model relates to a kind of bearing block, especially relates to a kind of jaw crusher bearing block, belongs to parts in the jaw crusher.

Background technology

The structure that is used in the bearing block in the jaw crusher at present as shown in Figure 1, the existing bearing seat generally is made up of three reinforcements 2 ' and the bearing block body 1 ' that has dead eye, wherein reinforcement 2 ' be distributed in dead eye under, other two reinforcements 2 ' are distributed in the left and right sides of the reinforcement 2 ' under the dead eye.There is the defective of the following aspects in the bearing block of this class formation: 1. the structure of bearing block is firm inadequately, and the insufficient strength of three reinforcements 2 ' because that the condition of work of jaw crusher is disliked very much is strong, often has impact type load, thereby causes bearing block to damage; Wherein reinforcement 2 ' be distributed in dead eye under because jaw crusher is when work, the impact type load maximum that is subjected under the dead eye causes the reinforcement at this place to be very easy to damage, thereby has reduced device '.

The utility model content

The purpose of this utility model is to overcome above shortcomings in the prior art, and a kind of sound construction is provided, and is reasonable in design, the jaw crusher bearing block of long service life.

The technical scheme in the invention for solving the above technical problem is: this jaw crusher bearing block is made up of the bearing block body and the reinforcement that have dead eye, its characteristics are: shown in reinforcement by a reinforcement, No. two reinforcements, No. three reinforcements and No. four reinforcements are formed, shown in a reinforcement, No. two reinforcements, No. three reinforcements and No. four reinforcements all are fixed on the bearing block body, this reinforcement, No. two reinforcements, No. three reinforcements and No. four reinforcements all are positioned at the below of the horizontal symmetry-line of dead eye, shown in reinforcement and No. four reinforcements about the center line symmetry of bearing block body, shown in No. two reinforcements and No. three reinforcements about the center line symmetry of bearing block body.

The center line of a reinforcement, No. two reinforcements, No. three reinforcements and No. four reinforcements all passes through the center of circle of dead eye shown in the utility model.

Reinforcement shown in the utility model be shaped as cuboid.

A reinforcement, No. two reinforcements, No. three reinforcements and No. four reinforcements all are fixed by welding on the bearing block body shown in the utility model.

The utility model compared with prior art, have the following advantages and effect: be provided with four reinforcements, strengthened the bulk strength of bearing block, and reinforcement and No. four reinforcements are about the center line symmetry of bearing block body, No. two reinforcements and No. three reinforcements are about the center line symmetry of bearing block body, promptly do not have in four reinforcements a reinforcement be positioned at dead eye under, increased the mechanical strength of jaw crusher bearing block, avoided reinforcement to be subjected to the influence of maximum impact type load, not only can prolong the service life of jaw crusher, reduce frequency of maintenance and maintenance cost, and improved production efficiency.

Structural design of the present utility model is very simple, low cost of manufacture.

Description of drawings

Fig. 1 is the structural representation of jaw crusher bearing block in the prior art;

Fig. 2 is the structural representation of the utility model embodiment.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.

Embodiment:

Referring to Fig. 2, jaw crusher bearing block in the present embodiment is made up of reinforcement 1, No. two reinforcements 2, No. three reinforcements 3, No. four reinforcements 4 and the bearing block body 5 that has a dead eye 6, wherein the shape of reinforcement 1, No. two reinforcements 2, No. three reinforcements 3 and No. four reinforcements 4 is rectangular-shaped, and the structure of bearing block body 5 is same as the prior art or similar.

Straight line k is the center line of bearing block body 5, and bearing block body 5 is about center line k symmetry; Straight line h is the horizontal symmetry-line of dead eye 6, and dead eye 6 is about horizontal symmetry-line h symmetry, and horizontal symmetry-line h is horizontal.Reinforcement 1 in the present embodiment, No. two reinforcements 2, No. three reinforcements 3 and No. four reinforcements 4 all are fixed by welding on the bearing block body 5, and reinforcement 1, No. two reinforcements 2, No. three reinforcements 3 and No. four reinforcements 4 all are positioned at the below of dead eye horizontal symmetry-line h.

A reinforcement 1 in the present embodiment and No. four reinforcements 4 are about bearing block body center line k symmetry, No. two reinforcements 2 and No. three reinforcements 3 are also about bearing block body center line k symmetry, make reinforcement 1, No. two reinforcements 2, No. three reinforcements 3 and No. four reinforcements 4 can either bring into play the effect of ruggedized construction, can effectively avoid to produce the position under the dead eye 6 of maximum impact formula load again, increase the mechanical strength of bearing block greatly, also reduced the fault rate of bearing block simultaneously.

The center line of reinforcement 1 in the utility model, No. two reinforcements 2, No. three reinforcements 3 and No. four reinforcements 4 can make that the structure of bearing block is more firm all through the center of circle of dead eye 6.

Above content described in this specification only is to the explanation of the utility model structure example.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount the defined scope of these claims, all should belong to protection domain of the present utility model.
