One end of a PTO driving shaft of the PTO device is provided with a driving gear, the driving gear is mashed with two driven gears, two end faces of the driving gear are respectively provided with two driving bearings, two end faces of each driven gear are respectively provided with two driven bearings, the driving bearing 8 close to one end of a PTO cover and the driven bearings are provided with clamping rings, the PTO driving shaft penetrates through a PTO casing, the PTO cover is provided with a middle hole, a sealing gasket or sealing gum is arranged between the PTO casing and the PTO cover, and an oil seal is respectively arranged on the insides of two ends of the middle hole. The PTO device has a plurality of power take-off ports, achieves a plurality of auxiliary functional requirements of the dump truck for the mining for a hydraulic system, is matched with a modern constant power hydraulic pump, and guarantees the truck to be provided with constantly stable shifting, lifting, braking and cooling functions. Compared with a traditional power take-off mode, the PTO device is simple and compact in structure, high in reliability, low in cost, simple and convenient to maintain and the like.
Description
Technical field
The utility model patent relates to a kind of mine truck takeoff output PTO device, belongs to the mining dump truck field.
Background technology
Equipment output function beyond traditional automobile running system (as lifting, turn to etc.) all is from driving engine or transmission gearbox configuration power taking mouth, and power takeoff is installed on the power taking mouth, and power takeoff drives Hydraulic Pump and realizes.This way of output is not only arranged dispersion, takies than large space, is unfavorable for the servicing ease; Simultaneously reliability is lower, and the damage of Hydraulic Pump often causes the secondary damage of driving engine and transmission gearbox, and the power takeoff on driving engine and the transmission gearbox costs an arm and a leg, and the coupling cost is higher.
Summary of the invention
It is a kind of simple in structure, compact that the purpose of this utility model is to provide, the reliability height, and cost is lower, the takeoff output of mine truck easily PTO device easy to maintenance.
Technical solution:
One end of the utility model PTO axle drive shaft is installed driving gear, two driven gears of driving gear engagement, the both ends of the surface of driving gear are respectively installed two active bearings, the both ends of the surface of driven gear are respectively installed two driven bearings, cover on the active bearings of an end and the driven bearing near PTO snap ring is installed, the PTO axle drive shaft passes PTO shell and PTO lid interstitial hole, and inboard, interstitial hole two ends is installed oil sealing respectively, is lined with packing seal or sealant between PTO shell and the PTO lid.
The utlity model has a plurality of function power taking mouths, can realize of the requirement of present quarry tipper, be complementary with permanent power Hydraulic Pump of modern times to a plurality of additional functioies of hydraulic efficiency pressure system, can guarantee vehicle have permanent steady turn to, functions such as lifting and braking cooling.Compare with traditional power taking mode, have simple in structurely, compact, reliability height, cost are lower, characteristics such as convenience easy to maintenance.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that function of the present utility model is implemented scheme of installation.
The specific embodiment
The utility model comprises PTO lid 1, two driven gears 2, driving gear 3, two oil sealings 4, three snap rings 5, PTO shell 6, four driven bearings 7, two active bearings 8, axle drive shaft 9, one end of PTO axle drive shaft 9 is installed driving gear 3, two driven gears 2 of driving gear 3 engagements, the both ends of the surface of driving gear 3 are respectively installed two active bearings 8, the both ends of the surface of driven gear 2 are respectively installed two driven bearings 7, cover on the active bearings 8 of 1 one ends and the driven bearing 7 near PTO snap ring 5 is installed, adding packing seal or sealant between PTO lid 1 and the PTO shell 6 is fastened on above-mentioned parts in PTO shell 6 and the PTO lid 1, axle drive shaft 9 passes the interstitial hole behind PTO shell 1 and PTO lid 6 fastenings, and inboard, interstitial hole two ends is installed oil sealing 4 respectively.PTO spacer ring 12 1 ends are installed on the clutch bell 11, and PTO assembly 13 is installed in the other end of PTO spacer ring 12, axle drive shaft 9 in the PTO assembly 13 and coupler 14 engagements that are installed on the flywheel 15.
The lifting of the utility model quarry tipper, turn to and coil the left and right sides that braking refrigerant fluid press pump is installed in the PTO device respectively, the driven gear 2 in the turning cylinder of the pump housing and the PTO device meshes.
When driving engine moves, engine crankshaft drives the flywheel rotating operation, horsepower output and moment of torsion, process and flywheel bonded assembly coupler 14, be delivered to reposefully with coupler 14 ingear PTO axle drive shafts 9 on, PTO axle drive shaft 9 drives and its ingear driving gear 3, driving gear 3 drives driven gear 2, the Hydraulic Pump turning cylinder and the driven gear 2 that are meshed with driven gear 2 rotate, Hydraulic Pump provides the propulsion source of these functions, make hydraulic oil flow by the pump housing to each hydraulic valve block, come the scope of modulated pressure oil flow size and function action by the valve piece, and then the turning to of realization car load, functions such as lifting and braking cooling.
Be that engine crankshaft drives engine flywheel horsepower output and moment of torsion, process and flywheel bonded assembly coupler, behind its vibration damping and noise reduction, be delivered to reposefully with coupler ingear axle drive shaft on, axle drive shaft drives and its ingear driven wheel, driven wheel drives driven gear, the Hydraulic Pump turning cylinder that is meshed with the driven gear wheel hub rotates with driven gear, Hydraulic Pump provides power for hydraulic oil, make hydraulic oil flow through hydraulic valve block, final by hydraulic valve block modulated pressure oil flow and function practical range, thus realize turning to of car load, functions such as lifting and braking cooling.It is a kind of simple in structure, compact that the purpose of the utility model patent is to provide, the reliability height, and cost is lower, the mode of takeoff output easily easy to maintenance.
