The clutch claw is connected with a hanging ring. The other end of the clutch shaft is installed in a sliding way seat. A shifting fork used for driving the clutch shaft to slide laterally along the sliding way seat is installed on the sliding way seat. A locking screw which achieves the locking and locating functions is further arranged on the sliding way seat. The grader lower end main shaft supporting device is reasonable in structural design, capable of preventing a rolling bearing from being corroded and abraded by water and sand in a groove, long in service life, low in accident rate and capable of saving resources.
Description
Technical field
The utility model relates to a kind of grader lower end main shaft support device, belongs to grader lower end main shaft support apparatus structure technical field.
Background technology
At present, during the helical axis lower end rolling bearing portion of grader is arranged in tank, though the good very quick-wearing that soaks into that is unable to undergo cement sand of existing rolling bearing pedestal design sealing easily causes and stops production and change parts.
Above-mentioned design is through being used for many years, it is found that after its shortcoming, reform into again rubber plain bearing housing or nylon plain bearing housing, although cost is lower, easy to maintenance, but its harm is very large, because it is without sealing device, very soon slotted hole has been worn into in seat hole, wearing into gradually after slotted hole, helical axis parts also and then decline gradually, the bearing value of plain bearing housing is almost eliminated, weight all concentrates in helical blade outer rim, the silt particle harder by bottom land supports, supporting due to silt particle, helical blade wearing and tearing are also very fast, and helical axis parts part weight can produce very large resistance by silt particle supporting completely, larger for driving section loss, because supporting portion is by displacement, produce after larger resistance, helical axis also produces and radially bends thereupon, lower slider support holes is ground into slotted hole, often there is disconnected macro-axis accident in spire, cause the off-time long, wealth, thing, manpower waste greatly, very undesirable.
Summary of the invention
The purpose of this utility model is to solve the weak point that above-mentioned prior art exists, a kind of reasonable in design is provided, can guarantees that rolling bearing is not subject to the husky etch of trough inner water and wearing and tearing, long service life, accident rate is low, the grader lower end main shaft support device economizing on resources.
The utility model is achieved through the following technical solutions:
Grader lower end main shaft support device, its special character is to comprise the clutch shaft 7 that is installed on the outside and clutch pawl 4 that is connected with the helical axis 1 of grader of grader, is used in conjunction with clutch pawl 4, clutch pawl 4 is connected with suspension ring 5, the other end of clutch shaft 7 is installed in slideway base 17, fork 10 for driving clutch shaft 7 to horizontally slip along slideway base 17 is installed on slideway base 17, the tie down screw 11 of locking positioning effect has also been housed on slideway base 17;
Described clutch shaft 7 is provided with filler chamber 6 near one end of clutch pawl 4, between filler chamber 6 and clutch shaft 7, by filler 18, seals, and filler chamber's gland 8 is installed in filler chamber 6;
Described clutch shaft 7 is provided with bearing block 13 and bearing block gland 15 near one end of slideway base 17, and bearing block 13 is fixedly connected with by round nut 14 and bearing 16 with bearing block gland 15;
The below of described grader is provided with cell body 19, and slideway base 17 is connected with cell body 19 by support post;
On described slideway base 17, be provided with for the fixing fork support 12 of fork 10.
Grader of the present utility model lower end main shaft support device, reasonable in design, each parts are used in conjunction with, and can guarantee that rolling bearing is not subject to the husky etch of trough inner water and wearing and tearing, need not change parts of bearings, guarantee maximum use of life-span, more can guarantee normal production, can not have an accident, make helical axis running more better than existing design, not easily broken macro-axis, the loss that reduction expense and accident stop production and cause, has good application prospect.

The specific embodiment
Below with reference to accompanying drawing, provide the specific embodiment of the present utility model, be used for the utility model to be described further.
Embodiment 1
The grader lower end main shaft support device of the present embodiment, comprise the clutch shaft 7 that is installed on the outside and clutch pawl 4 that is connected with the helical axis 1 of grader of grader, is used in conjunction with clutch pawl 4, support 3 and blade 2 are installed on helical axis 1, clutch pawl 4 is connected with suspension ring 5, the other end of clutch shaft 7 is installed in slideway base 17, fork 10 for driving clutch shaft 7 to horizontally slip along slideway base 17 is installed on slideway base 17, the tie down screw 11 of locking positioning effect has also been housed on slideway base 17; Clutch shaft 7 is provided with filler chamber 6 near one end of clutch pawl 4, between filler chamber 6 and clutch shaft 7, by filler 18, seals, and filler chamber's gland 8 is installed in filler chamber 6; Clutch shaft 7 is provided with bearing block 13 and bearing block gland 15 near one end of slideway base 17, and bearing block 13 is fixedly connected with by round nut 14 and bearing 16 with bearing block gland 15; The below of grader is provided with cell body 19, and slideway base 17 is connected with cell body 19 by support post; On slideway base 17, be provided with for the fixing fork support 12 of fork 10.
Operation principle: when ore dressing plant system equipment overhaul stops production, when 1 of helical axis if desired promotes, only the screw at shaft flange place is unloaded, by fork 10, drive clutch shaft 7 to slide along slideway base 17 is inner, thereby make clutch shaft 7 away from clutch pawl 4, now, by suspension ring 5, promote helical axis 1, if not repairing cell body 19 leaks, as far as possible by the interior solids emptying of cell body 19, can not unload flange screw, the trouble that also need not promote.
The beneficial effects of the utility model:
1, guarantee that rolling bearing is not subject to the husky etch of trough inner water and wearing and tearing, need not change parts of bearings, guarantee maximum use of life-span, more can guarantee normal production, can not have an accident;
2, guarantee that helical axis running is than intrinsic ideal, not easily broken macro-axis, the loss that cost saving and accident stop production and cause;
3, through improving rear blade light abrasion, long service life, saves investment.
