Description
Technical field
Technique for fixing field is installed the present invention relates to bearing, and in particular to a kind of bearing block structure and the jaw with it are broken
Broken machine.
Background technology
Jaw crusher is widely used in various ore deposits in the industries such as mine smelting, building materials, highway, railway, water conservancy and chemical industry
Stone and bulk materials it is broken, its working portion includes determine jaw and dynamic jaw, determine jaw vertically or upper end summary flare be fixed on body
On antetheca, jaw position deflection is moved, up big and down small crusher chamber is formed with determining jaw.Dynamic jaw determines jaw relatively under the drive of eccentric shaft
Do periodic reciprocating motion, when and separate, when and it is close, simulate two jaw movements of animal and complete material crushing operation.It is dynamic
Jaw is installed on eccentric shaft, and work is driven by eccentric shaft, and eccentric shaft is the main shaft of jaw crusher.
Usually, main shaft is arranged in frame by bearing, and bearing is arranged on and is arranged on the bearing block in frame, bearing
Upper press cover of the seat by the lower base that is fixedly mounted in frame with that can be fixedly mounted on lower base is constituted, and both are consolidated by bolt
Fixed connection.Material applies a reaction force substantially perpendicular to the dynamic jaw plane of disruption to moving jaw during due to crushing work,
And applying a power generally upwards during bracket work to dynamic jaw, these power eventually apply the work away from lower base to upper press cover
Firmly, so that the bolt connection piece stress for fixing upper press cover can be caused larger.
A kind of existing bearing block is as shown in figure 1, including upper press cover and lower base, upper press cover is removably installed in lower seat
On body, and the inwall of upper press cover and the inwall of lower base surround the bearing mounting hole for installing bearing jointly.The two of upper press cover
End offers bolt mounting holes respectively, and upper press cover is fixed on lower base by bolt.In order that bolt is with bigger
Bearing capacity is stretched, it is existing that two upper bolt mounting holes 10 along the axial direction arrangement of bearing mounting hole are set in limited space,
The two ends of lower base offer two along the axial direction arrangement, corresponding with the upper bolt mounting holes 10 of bearing mounting hole respectively
Lower bolt mounting holes, by the way that bolt is respectively charged into corresponding upper bolt mounting holes 10 and lower bolt mounting holes, to realize upper pressure
The detachable installation of lid and lower base.Because the installing space of bearing block is limited, so the axial length of bearing block is also limited, this
Also require that the diameter of two axially aligned bolts can not be too big, thus the tensile strength of bolt can also compare by
Limit.
The content of the invention
Therefore, the technical problem to be solved in the present invention is the connection upper press cover for overcoming bearing block of the prior art with
The less defect of tensile strength of the connector of pedestal, so as to provide a kind of connection that can increase and connect upper press cover and lower base
The bearing block structure of the intensity of part and the jaw crusher with it.
The present invention provides a kind of bearing block structure, including lower base and the upper pressure being removably installed on the lower base
The inwall of lid, the inwall of the upper press cover and the lower base surrounds the bearing mounting hole for installing bearing jointly,
The two ends of the upper press cover form at least two and led to along the fixation of the arranged radially of the bearing mounting hole respectively
Hole, the two ends of the lower base form fixed engagement hole corresponding with the fixed via quantity and position respectively；
The upper press cover is by being inserted in the fixed via, and the company connected with the corresponding fixed engagement hole engagement
Fitting is removably installed on the lower base.
The two ends of the upper press cover form two fixed vias respectively, and the two ends of the lower base are formed respectively
Two fixed engagement holes.
The two ends of the upper press cover form the platform consistent with the quantity of the fixed via respectively, each fixation
Forming through holes are in the corresponding platform；And the upper surface of the platform of the close bearing mounting hole hole heart is higher than remote
The upper surface of the platform of the bearing mounting hole hole heart.
Also include being arranged at any bearing mounting hole end, and connect the homonymy of the upper press cover and the lower base
Reinforcing member.
The reinforcing member is annular in shape, and the main shaft that its central through hole is adapted to mount on the bearing is passed through.
The side of the upper press cover and/or the lower base form formed on deep-slotted chip breaker, the reinforcing member with it is described
The projection that deep-slotted chip breaker coordinates, the reinforcing member by the cooperation of the projection and the deep-slotted chip breaker respectively with the upper press cover and institute
Lower base is stated to be fixedly connected.
The two ends of the bearing mounting hole are respectively arranged with the reinforcing member.
The fixed engagement hole is screwed hole, and the connector is threaded connector.
The present invention also provides a kind of jaw crusher, including above-mentioned bearing block structure.
