Description
Technical field
The present invention relates to a kind of large-scale fixing structure for pin shaft of quarry tipper, and being specifically a kind of quarry tipper that is applied to will
Rear axle housing is fixed to the fixed structure of the large-scale bearing pin of vehicle frame.
Background technology
Mine truck is the key equipment in surface mine exploitation and extensive earthworks, is transported for ore or the earthwork
Defeated professional equipment, have the characteristics that load-carrying is big, operating efficiency is high, residing working environment is severe, and operating mode is complicated.It is mining at present
Truck has the trend developed towards large, hugeization direction, and the requirement to the bearing pin stress of mine truck is harsher.
The pin diameter of large-scale mine dumper is big, weight is big, is acted on by complicated superimposed load.Current large-scale bearing pin in order to
Axial moving is reduced, more using interference fits, extremely difficult by being installed after freezing bearing pin, bearing pin fixed dam is more using weldering
Mode is connect to be welded together with bearing pin, it is high to bearing pin requirements of installation space so as to be installed from one side.
The content of the invention
The technical problems to be solved by the invention are the defects of overcoming prior art, there is provided one kind is applied to quarry tipper
Rear axle housing is fixed to the fixed structure of the large-scale bearing pin of vehicle frame.
To reach above-mentioned purpose, the present invention provides a kind of large-scale fixing structure for pin shaft of quarry tipper, including several pins
Axle mounting bracket, several baffle plates and bearing pin, several described bearing pin mounting brackets equidistantly vertically be arranged in parallel, the bearing pin
Extend transversely through several bearing pin mounting brackets, several described baffle plates be symmetrically fixedly installed on the bearing pin left end,
Right-hand member, the width of several baffle plates are more than the width of the bearing pin.
Preferentially, including two bearing pin mounting brackets.
Preferentially, including two spacing cambridge rings, two spacing cambridge rings are symmetrically fixedly installed on the bearing pin
Left end and right-hand member, two spacing cambridge rings are respectively positioned between the baffle plate, the bearing pin, four corners of the bearing pin
Equal chamfering, two spacing cambridge rings respectively open up the U-type groove for coordinating the chamfering, two spacing cambridge ring difference
Be connected together left end, the right-hand member of the bearing pin.
Preferentially, including the corresponding spacing cambridge ring is pressed on described by two baffle plates, two baffle plates respectively
On bearing pin.
Preferentially, including several fixing bolts, several described fixing bolts are symmetrically each passed through two gears
The spacing cambridge ring is pressed on the bearing pin by plate, the bearing pin.
Preferentially, including four fixing bolts.
The beneficial effect that the present invention is reached：
The medium-and-large-sized bearing pin of prior art uses interference fits more in order to reduce axial moving, but is installed also very after freezing bearing pin
Difficulty, and bearing pin both ends can be used small all using mode is detachably fixed using present apparatus bearing pin fit system in the present apparatus
Gap coordinates, so as to reduce the requirement to installing space.The present apparatus solves the pin bearing of quarry tipper by cross force mistake
The problem of moving when big, and solve the bilateral installation question of bearing pin fixed component, reduce the set-up time, reduce labor
Fatigue resistance, mounting cost is reduced, reduce potential safety hazard when installing large-scale bearing pin, reduce quarry tipper due to bearing pin
Critical component case accident caused by coming off, it ensure that vehicle service life.
Because the wedge-shaped gradient of spacing cambridge ring is identical with the gradient of large-scale bearing pin, it ensure that large-scale bearing pin is installed with bearing pin
The axiality of bracket pins axis hole.
Brief description of the drawings
Fig. 1 is the structure chart of the present invention；
Fig. 2 is the structure chart of the present invention.
Mark meaning in accompanying drawing, 1- bearing pins, 2- fixing bolts, 3- baffle plates, the spacing cambridge rings of 4-；5- bearing pin mounting brackets.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings, and following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
A kind of large-scale fixing structure for pin shaft of quarry tipper, including several bearing pin mounting brackets, several baffle plates and pin
Axle, several described bearing pin mounting brackets equidistantly vertically be arranged in parallel, and the bearing pin extends transversely through several bearing pin peaces
Support is filled, several described baffle plates are symmetrically fixedly installed on the left end of the bearing pin, right-hand member, the width of several baffle plates
More than the width of the bearing pin.
Further, including two bearing pin mounting brackets.
Further, including two spacing cambridge rings, two spacing cambridge rings are symmetrically fixedly installed on the pin
The left end and right-hand member of axle, two spacing cambridge rings are respectively positioned between the baffle plate, the bearing pin, four sides of the bearing pin
The equal chamfering in angle, two spacing cambridge rings respectively open up the U-type groove for coordinating the chamfering, two spacing cambridge rings point
Be not connected together left end, the right-hand member of the bearing pin.
Further, including the corresponding spacing cambridge ring is pressed on institute by two baffle plates, two baffle plates respectively
State on bearing pin.
Further, including several fixing bolts, several described fixing bolts are symmetrically each passed through described in two
The spacing cambridge ring is pressed on the bearing pin by baffle plate, the bearing pin.
Further, including four fixing bolts.
Large-scale bearing pin 1 is installed in bearing pin mounting bracket 5 by the present invention, and spacing cambridge ring 4 is installed into the both ends of bearing pin 1,
Pin shaft baffle 3 is fixed to the both ends of bearing pin 1 with fixing bolt 2, and fixing bolt 2 is tightened to rated moment.By tightening
Fixing bolt 2 makes pin shaft baffle 3 compress spacing cambridge ring 4, so that spacing cambridge ring 4 is firmly pressed to large-scale bearing pin 1
On the wedge surface at both ends.
Because bearing pin both ends are all using mode is detachably fixed, so as to reduce the requirement to installing space.Due to spacing
The wedge-shaped gradient of cambridge ring 4 is identical with the gradient of large-scale bearing pin 1, ensure that large-scale bearing pin 1 and bearing pin mounting bracket pin shaft hole
Axiality.
Interference fits are used to reduce axial moving due to large-scale bearing pin more, but installed after freezing bearing pin also very tired
Difficulty, and using present apparatus rear pin shaft to coordinate can use small―gap suture to coordinate, and solve the pin bearing of quarry tipper by cross force
The problem of moving when excessive and the bilateral installation question of bearing pin fixed component, reduce the set-up time, reduce labor intensity,
Mounting cost is reduced, potential safety hazard when installing large-scale bearing pin is reduced, reduces quarry tipper and made because bearing pin comes off
Into critical component case accident, ensure that vehicle service life.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvement and deformation can also be made, these are improved and deformation
Also it should be regarded as protection scope of the present invention.
