The specific embodiment:
Below in conjunction with specific embodiment and diagram, further set forth the present invention.
As shown in Figure 1, automatic clutch device on a kind of shunting winch countershaft is made up of countershaft 1, copper sheathing 10, wheel word 4, spacer 5, bearing 12, end cap 13, bearing seat 6, slide block device 3 and feather key 8.Wherein: countershaft 1 is provided with the side that one section plug helix 2 is positioned at close wheel word 4, and free-running fit has copper sheathing 10 on the described countershaft 1, wheel word 4 and copper sheathing 10 interference fit; Copper sheathing 10 1 ends connect the shaft shoulder of countershaft 1, and the other end connects an end of spacer 5, an end of the other end connection bearing 12 of spacer 5, and the other end of bearing 12 is connected with end cap 13; Spacer 5 and bearing 12 skies are enclosed within on the countershaft 1, and end cap 13 is by felt collar 11 and countershaft 1 interference fit; The inner peripheral surface of bearing seat 6 is installed by felt collar 11 and spacer 5 interference fit, and the end face of described bearing seat 6 is connected by the end face of bolt 7 and end cap 13; The inside of slide block device 3 is provided with axial groove, and described feather key 8 is installed in by screw 9 in the axial groove of slide block device 3, and feather key 8 is nested in the plug helix of countershaft 1, and the plug helix 2 of the two sides of feather key 8 and countershaft 1 contacts.
As shown in Figure 2, described wheel word 4 comprises gear 14, pulley axle 15 and leading sheave 17, gear 14 is provided with helical tooth M16 at the end face near slide block device 3 one sides, the two ends of helical tooth M16 are provided with pulley groove 18, pulley groove 18 is provided with manhole, described pulley axle 15 is installed in the through hole of pulley groove 18, and leading sheave 17 skies are enclosed within on the pulley axle 15.
As shown in Figure 3, described slide block device 3 comprises slide block 19, pulley axle 15 and leading sheave 17, the position corresponding with the helical tooth M16 of gear 14 at slide block 19 is provided with helical tooth N20, the two ends of helical tooth N20 are provided with pulley groove 18, pulley groove 18 is provided with manhole, described pulley axle 15 is installed in the manhole of pulley groove 18, and leading sheave 17 skies are enclosed within on the pulley axle 15.
The automatic clutch device working process is as follows on the shunting winch countershaft of the present invention:
When countershaft 1 is just changeing, because feather key 8 is enclosed within the plug helix 2 of countershaft 1, the two sides of feather key 8 and plug helix 2 contacts side surfaces produce friction force, so feather key 8 moves under the effect of this friction force, and the inside of slide block device 3 has axial groove, described feather key 8 is installed in the axial groove of slide block device 3 by screw 9, makes feather key 8 drive slide blocks 19 and rotatablely moves as spiral along plug helix 2.In the pulley groove 18 on the helical tooth M16 leading sheave 17 is installed, the pulley groove 18 on the helical tooth N20 is equipped with leading sheave 17.When the leading sheave 17 of the leading sheave 17 of slide block device 3 and wheel word 4 contacts, rotate mutually because the friction force that produces during contact drives this a pair of leading sheave 17, thereby avoided the generation of slide block stuck phenomenon.Thereby, it is mobile that slide block 19 continues rotation, behind the rotation half cycle, the position that the helical tooth N20 of slide block 19 and the helical tooth M16 of gear 14 combine, slide block 19 can't continue mobile, rotates synchronously with countershaft 1, and realization gear 14 is followed the combination of countershaft 1 and rotated together, the drive cable drum rotates, and regains steel rope and tractive load.When countershaft 1 counter-rotating, slide block 19 is along plug helix 2 counter motions, and the helical tooth M16 of gear 14 and the helical tooth N20 of slide block 19 break away from combination, and gear 14 breaks away from conjunction with countershaft 1 and stops operating, cause cable drum to be in free state, can put steel rope outward by external force.
More than show and described groundwork of the present invention and principal character; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
