Description
Technical field
The invention belongs to the push-in external water pump of a kind of mining diesel engine of the two cooling systems of anti-explosion diesel engine for mine application, particularly anti-explosion diesel engine.
Background technique
The employed water pump of present anti-explosion diesel engine for mine is belt wheel transmission type water pump, and is for the cooling system of the strict mining diesel engine of requirement of explosion proof, not enough below it exists:
1, if directly reduce the belt wheel of built-in water pump, improve rotating speed, consumed power is too big;
2, if directly add a belt wheel transmission type water pump, just must increase train;
3, transmission stability is poor, noise is big.
Just because of above reason, make the anti-explosion diesel engine for mine arrangement of parts difficult, function of use is difficult to satisfy.
Summary of the invention
The objective of the invention is provides a kind of simple in structure, easy for installation to above-mentioned deficiency, and power is little, the push-in external water pump of the mining diesel engine that reliability is high.
The technical solution adopted for the present invention to solve the technical problems is: the push-in external water pump of a kind of mining diesel engine of the present invention comprises water pump cover; One end of water pump cover is an end cap; Water pump vane live axle, impeller in the water pump cover; Water outlet on the water pump cover, water intake, water pump vane live axle are stretched out by the other end of water pump cover and connect female splined shaft; In the female splined shaft outside splined support cover is arranged, between the inboard of the outside of female splined shaft and splined support cover bearing is installed; The rear end of splined support cover be a bowl end shape, and the water pump vane live axle passes at the bottom of by bowl, and the water pump vane live axle overlaps with splined support at bowl the end establishes motive sealing; The front opening periphery mounting flange of splined support cover has the installation attachment hole on the flange plate.
The parameter of described female splined shaft is: the number of teeth 16, modulus 0.75,30 ° of pressure angles, effective length 24 ± 0.5 mm.
The water pump vane live axle stretches out swivel nut by the other end of water pump cover, female splined shaft) be threaded with swivel nut.
The ear end face outer ring of described flange plate is connected with water pump cover.
The impeller drive shaft of push-in external water pump of the present invention is through the female splined shaft that is threaded; Reserve mounting hole on the adpting flange of housing; Link to each other with the casing flange of line shaft through mounting hole during use; Female splined shaft matches with external splines on the line shaft, accomplishes docking of push-in external water pump and power input shaft.Use spline to replace the drive pulley transmission like this, not only reduced push-in external water pump input shaft power, reduced the transmission noise, simultaneously easy for installation, saved the space.

Embodiment
Combination accompanying drawing and mode of execution are made detailed explanation to the present invention below.
Fig. 1, Fig. 2 are the push-in external water pump structure figure of mining diesel engine: the push-in external water pump of a kind of mining diesel engine of the present invention comprises water pump cover 1; One end of water pump cover 1 is an end cap 2; Water pump vane live axle 3, impeller 4 in the water pump cover 1; Water outlet 5 on the water pump cover 1, water intake 6, water pump vane live axle 3 are stretched out by the other end of water pump cover 1 and connect female splined shaft 8; Splined support cover 7 is arranged in female splined shaft 8 outsides, between the inboard of the outside of female splined shaft 8 and splined support cover 7 bearing 10 is installed; The rear end of splined support cover 7 be a bowl end shape, and water pump vane live axle 3 is by passing at the bottom of the bowl, establishes motive sealing 7a between at the bottom of water pump vane live axle 3 and splined support are overlapped 7 bowls; The front opening of splined support cover 7, peripheral mounting flange 9 has the attachment hole of installation 9a on the flange plate 9.
The parameter of described female splined shaft 8 is: the number of teeth 16, modulus 0.75,30 ° of pressure angles, effective length 24 ± 0.5 mm.
Water pump vane live axle 3 stretches out swivel nut 3a by the other end of water pump cover 1, and female splined shaft 8 is threaded with swivel nut 3a.
The ear end face outer ring of described flange plate 9 is connected with water pump cover 1.
Fig. 3 is user mode figure of the present invention:
When the push-in external water pump of mining diesel engine uses; Through screw 11 the installation attachment hole 9a on the flange plate 9 is linked to each other with the casing land 15 of mine explosion-suppression generator 12; External splines 16 on the line shaft 14 of female splined shaft 8 and flame-proof type generator 12 matches, and female splined shaft 8 is through the water pump vane live axle 3 that is threaded, 4 rotations of impeller drive shaft 3 impeller; Circulating water gets into from water intake 6, flows out from water outlet 5 high pressure again.During this reality was used, flame-proof type generator 12 adopted and the shared poly Vbelt transmission of anti-explosion diesel engine, and the line shaft 14 of flame-proof type generator 12 is fixing with poly Vbelt wheel 13.
Push-in external water pump of the present invention and flame-proof type generator fuse, and have so not only effectively saved the space in the anti-explosion diesel engine cabin, and the coaxial power with the flame-proof type generator rationally utilizes simultaneously, for cooling system provides power source.
