Abstract
The utility model relates to a novel structure of a speed changing box of an adjustable coupler for a driving cooling fan and a pump in a diesel locomotive. In prior art, the output rotation speed of a speed changing box for a driving cooling fan and a pump can not be adjusted, so that the cooling water temperature of a diesel engine fluctuates largely. Driving parts bear large impact load and are easy to damage early, and the operation is inconvenient. The utility model adopts an adjustable coupler arranged horizontally and matched with an inlet adjusting form control system to realize the automatic stepless fan speed adjustment according to the change of the cooling water temperature of the diesel engine. The fluctuation of the water temperature is small, the operating condition of the diesel engine is improved, the service life of relevant parts is extended, and obvious fuel saving effect is provided.
Description
The utility model is the new construction that a kind of diesel locomotive driving cooling fan and water pump are used change speed gear box.
In prior art, the change speed gear box (as shown in Figure 2) that diesel locomotive driving cooling fan and water pump are used.By input shaft (28) by friction clutch (27), be supported on hollow shaft (26), cylindrical wheel (24) and (29), conical gear (21) and (30), output shaft (31) on bearing (25) and (23), drive cooling fan.Input shaft (28) drives water pump (20) by internal tooth casing (22).Change speed gear box adopts lubrication by atomization, natural cooling.There is following point in the use:
Friction clutch (27) can only be controlled stopping of fan and change, thus unadjustable by the rotation speed of the fan of output shaft (31) output, cause the fluctuation of diesel coolant temperature big, both wasted diesel engine power, shortened the service life of diesel engine again.When the diesel engine master-hand closes friction clutch to the position, produce very big impact load, easily twist off fan vertical drive shaft, part infantile failure; For fear of twisting off vertical drive shaft, must reduce diesel engine speed when closing friction clutch, and then recover diesel engine speed, handle inconvenience, easily maloperation.Adopt lubrication by atomization, the cooling power deficiency, the lubricating oil temperature height, perishable, quickened the infantile failure of fastness.
The purpose of this utility model is: replace friction clutch by adopting adjustable impeller disk, but make the rotation speed of the fan automatically regulating.Equipped impeller disk inlet adjusting control system realizes automatically infinitely regulating rotation speed of the fan according to the variation of diesel coolant temperature, keeps diesel coolant temperature variation range in 6～7 ℃, reducing diesel engine power consumption, and raising parts service life.
Principle of work of the present utility model as shown in Figure 1.Drive impeller disk pump impeller (1) by pump impeller shaft (3),, drive impeller disk turbine (8) by the oil in the epitrochoidal chamber.The output shaft (13) of impeller disk turbine (8) by turbo-shaft (9), conical gear (12) and (14), drive fan drives cooling fan and rotates.Metering-in formula speed control system can be regulated the value that enters the power fluid in the coupler rotor chamber according to the variation of diesel coolant temperature, automatically regulates the output shaft rotating speed.
The utility model compared with prior art can be realized:
1. replace friction clutch with impeller disk, equipped impeller disk inlet adjusting control system has improved the diesel coolant mean temperature, saves fan power consumption about 30%.As be contained on the easterly type locomotive, every chassis every year can be fuel-efficient more than 22 tons.
2. diesel engine all can guarantee the coolant water temperature fluctuation range in 6～7 ℃ under any operating mode, thereby has improved the heat efficiency of diesel engine, has prolonged its service life.
3. rotation speed of the fan can automatically infinitely be regulated, and has simplified driver operation, has solved the problem that must return diesel engine handle when the diesel engine master-hand closes friction clutch to the position; And fundamentally solved the fan vertical drive shaft and twisted off and fan blade crackle and parts infantile failure problem.
4. strengthen the fan power deposit, improved the heat-sinking capability when high temperature season uses in upward slope and the many caverns area of growing up.
Accompanying drawing 1, diesel locomotive drive cooling fan and the water pump constructional drawing with adjustable impeller disk change speed gear box.
2, df diesel locomotive driving cooling fan and the water pump constructional drawing of rear transmission gear box.
Structure of the present utility model as shown in Figure 1, the turbo-shaft of its horizontal arrangement (9) is bearing on bearing (10), (11) and (18), and directly is connected with impeller disk turbine (8); Conical gear (12) is installed on the turbo-shaft (9) by key, the rotating speed that changes is passed to the output shaft (13) of drive fan by conical gear (12) and (14).Turbo-shaft (9) adopts hollow structure can make pump impeller shaft from wherein passing through, to drive water pump.Ball-bearing casing (10) is contained in the bearing carrier ring (19) with coro bearng (11), so that the assembly that mounting or dismounting are made up of turbine (9), bearing (10) and (11), bearing carrier ring (19), gear (12).Structural requirement bearing (11) is on the right side, and bearing (10) is on a left side.Ball-bearing casing (10) only bears the axial force on the turbo-shaft (9), bearing radial force not, prolonged its service life, diametral load on the turbo-shaft (9) is born by coro bearng (11) and (18), solve prior art centre bearer (25) and not only born axial force but also bearing radial force, the problem that service life is low.
Miniature gears (7), pump impeller (1), internal tooth casing (16) and the coro bearng (17) of ball-bearing casing (5), gerotor (6) are housed on the pump impeller shaft (3) from left to right successively, and pump impeller shaft (3) is bearing on bearing (5) and (17).Distance between bearing (5) and (17) makes input flange (4) cantilever short, vibrates little.Pump impeller (1) position between bearing (5) and (17), working stability.For key is connected, and can on axle, slide between the miniature gears (7) of internal gear pump (6) and the pump impeller shaft (3) to guarantee automatic compensation miniature gears (7) two side clearances in the running.The internal gear pump pressure fluctuation is little, and compact conformation is easy for installation.The enforced lubricating that it is used for collecting emptying change speed gear box bottom is with lubricating oil and coupler rotor oil, because spill pressure is low, so consumed power seldom.Be connected by adapter sleeve (2) between pump impeller shaft (3) and impeller disk pump impeller (1).Between pump impeller shaft (3) and the internal tooth casing (16) for key is connected, direct drive water pump (15) then.
The utility model is equipped with coupling device import oil mass adjustable type revolution speed control system. The water temperature variation is experienced by the thermostatic element that is connected on the diesel engine cooling water pipe by this system, provide variable pressure air signal by temperature control valve according to the action of thermostatic element, the valve port opening of control oil charge valve, change the value of oil in the coupler rotor chamber, thereby change the size of coupling device power output, realize the purpose of automatically infinitely regulating rotation speed of the fan according to the variation of diesel engine cooling water temperature.
Each fastness of the utility model all adopts enforced lubricating, and external refrigeration has prolonged service life of fastness.
