Description
Technical field
Gyratory crusher technical field is the utility model is related to, in particular it relates to which one kind can effectively stablize gyratory crusher
The radial positioning structure of bull gear.
Background technology
The adjustment of multicylinder hydraulic spindle breaker discharge gate size and the dismounting of mantle part drive big by hydraulic motor
Gear ring is rotated to realize, as shown in figure 1, former design bull gear 1 is held up by three support rollers 5, bull gear 1 engages work with little gear 2
Make, but bull gear endoporus does not position, thus 4 frees degree of bull gear in the horizontal plane only limit one degree of freedom, its
He is not to be restricted three degree of freedom, when adjusting discharge gate size or assembly and disassembly mantle part in work, it may appear that as follows
Several situations：
1st, because the unilateral active force by little gear of bull gear, bull gear can be moved to the direction away from little gear, caused
Bull gear and little gear teeth portion depart from, and ultimately result in adjustment or the dismounting mantle part cisco unity malfunction of discharge gate.
When discharge gate is adjusted in the 2nd, producing, bull gear is in away from little gear direction moving process, sometimes due to by ore deposit
The obstruction of the broken material such as stone, causes bull gear and pinion head mutually to answer back to, and such as stops hydraulic motor not in time, will lead
Cause big/little gear damage or broken teeth.
The content of the invention
The purpose of this utility model be overcome prior art it is above-mentioned deficiency and provide one kind can effectively reduce bull gear and
Little gear mutually damages possibility, ensures the bull gear radial positioning structure of gyratory crusher normal work.
The technical solution of the utility model is：A kind of radial positioning structure of gyratory crusher bull gear, including bull gear,
Bull gear periphery can be used to limit bull gear provided with least one with the driven gear of bull gear teeth portion engaged transmission, driven gear
Move radially.
The further technical scheme of the utility model is：It is three that the driven gear, which sets quantity, and outside bull gear
It is uniformly arranged on week.
The further technical scheme of the utility model is：Driven gear is provided with and is detachably connected with cone crusher body
Fixation clip, fixation clip is fixedly connected with the central shaft of driven gear.
The further technical scheme of the utility model is：Fixation clip is provided with through hole, and fixation clip passes through through hole and circle
Conic crusher fuselage bolt connection.
The further technical scheme of the utility model is：The through hole is to be available for fixation clip to be moved in bull gear radial direction
Dynamic long stripes through hole.
The utility model has following features compared with prior art：
1st, the setting of driven gear, four frees degree of bull gear in the horizontal plane are made to be limited, now bull gear
Will not random play when being influenceed by external force.
2nd, bull gear positioning is reliable, can effectively avoid bull gear and small gear ring that de- tooth, gear destruction or broken teeth etc. occurs now
As reducing fault power time, it is ensured that the normal work of gyratory crusher.
3rd, the replacement cost of bull gear spare part is also reduced while fault rate reduces.
4th, on fixation clip long stripes through hole design, make the operation of bull gear more flexibly adjustable, operator can basis
Production be actually needed or the degree of wear of bull gear teeth portion selection by driven gear bull gear radially carry out closer or far from
It is fixed, effectively increase the applicability of gyratory crusher.
Detailed construction of the present utility model is further described below in conjunction with the drawings and specific embodiments.
Brief description of the drawings
Fig. 1 is the positioning states schematic diagram of bull gear in the prior art；
Fig. 2 is the radial positioning structure schematic diagram of bull gear described in the utility model；
Fig. 3 is the partial enlarged drawing of I in Fig. 2.
Embodiment
Embodiment
As shown in figures 2-3：A kind of radial positioning structure of gyratory crusher bull gear, including bull gear 1, outside bull gear 1
It is provided with least one can be fixed with the driven gear 3 of the teeth portion engaged transmission of bull gear 1, the position of driven gear 3 and for limiting week
Bull gear 1 moves radially.
Gyratory crusher is provided with little gear 2, and bull gear 1 specifically, is passed through by being worked with the engaged transmission of little gear 2
Driven gear 3 is arranged on the relative position of little gear 2 or adjacent position can be limited the one degree of freedom of bull gear 1
System, so as to play a part of carrying out auxiliary positioning to bull gear.
To make four frees degree of bull gear 1 in a circumferential direction be limited, the setting of driven gear 3 in the present embodiment
Quantity is three, and is uniformly arranged on the direction of 360 ° of 1 periphery of bull gear.
Three driven gears 3 are uniformly arranged, and equivalent to a stable triangle is formed on the periphery of bull gear 1, are made big
The passive movement of gear ring 1 suffers restraints, will not random play when now bull gear is influenceed by external force.
Driven gear 3 is provided with the fixation clip 4 that is detachably connected with cone crusher body, fixation clip 4 with it is passive
The central shaft of gear 3 is fixedly connected, so as to which the position of driven gear 3 be fixed.
Fixation clip 4 is provided with through hole 41, and fixation clip is by through hole 41 and cone crusher body bolt connection, so
One, which carrys out fixation clip 4, to dismount at any time, i.e., driven gear 3 can also be dismounted with bull gear 1 at any time, add using reliable
Property.
Fixation clip 4 can be square, and through hole 41 is uniformly arranged on four angles of square fixation clip, makes fixation clip 4
The power that is fixed and clamped is uniform, so as to increase the engaged transmission reliability of driven gear 3.
To adapt to production status, the bolt that fixation clip 4 is connected with cone crusher body uses high-strength bolt.
To make driven gear 3 and the engaged transmission of bull gear 1 adapt to various working, it is easy to the cooperation between them
Away from progress flexible modulation, the through hole 41 in the present embodiment on fixation clip is to be available for fixation clip to be moved in bull gear radial direction
Long stripes through hole.
The design of long stripes through hole, make the operation of bull gear 1 more flexibly adjustable, operator can be according to the actual need of production
Want or the selection of the degree of wear of bull gear teeth portion radially carries out driven gear closer or far from fixation in bull gear.
Bull gear positioning is reliable in the present embodiment, can effectively avoid bull gear 1 and little gear 2 that de- tooth, gear destruction occurs
Or phenomena such as broken teeth, reduce fault power time, reduce rate of breakdown, it is ensured that the normal work of gyratory crusher it is same
When also reduce the replacement cost of bull gear spare part.
The utility model is not limited to above-mentioned concrete structure, as long as with the positioning essentially identical with the utility model
Structure just falls within the scope of protection of the utility model.
