The specific embodiment
A kind of low seam mining machinery rocking arm gear clutch as illustrated in fig. 1 and 2, comprise axle 4 and be installed in driving wheel 1 and driven pulley 3 on the axle 4, described driven pulley 3 is positioned at driving wheel 1 below, be installed with sliding pin 2 on the described driven pulley 3, described sliding pin 2 is perpendicular with axle 4, described axle 4 centers are provided with coupling bar 5, described coupling bar 5 is perpendicular with sliding pin 2, fixedly connected with sliding pin 2 in described coupling bar 5 upper ends, described coupling bar 5 lower ends are fixedly connected with pull bar 6, described pull bar 6 bottoms are provided with seal receptacle 13, are provided with dive key 12 between described axle 4 and the driven pulley 3.
In the utility model, described axle 4 is provided with keyway, and described dive key 12 is positioned at described keyway, and the quantity of described dive key 12 is 1-3.
As shown in Figure 1, described axle 4 upper ends are provided with end cap 1, and described axle 4 lower ends are provided with end cap 2 10, and end cap 1 and end cap 2 10 all are used for gear clutch is fixed on housing.
As shown in Figure 1, described pull bar 6 lower ends are provided with handle 7, and described handle 7 is positioned at seal receptacle 13 belows, all fixedly connected between described handle 7 and the pull bar 6 and between handle 7 and the end cap 2 10.Wherein, described handle 7 is fixedlyed connected with pull bar 6 by pin 11, and described handle 7 is fixedlyed connected with end cap 2 10 by dog screw 8.
As shown in Figure 1, inboard, described driving wheel 1 lower end is provided with the clutch spline 14 that is used to drive driven pulley 3 rotations.
In the utility model, sliding pin 2 couples together driven pulley 3, axle 4 and coupling bar 5, make driven pulley 3 to move along the axle slideway with coupling bar 5, and axle 4 is rotated with driven pulley 3; Handle 7 is connected with pull bar 6 by pin 11, makes pull bar 6 to move and to rotate with handle 7; Pull bar 6 is connected with coupling bar 5 with bearing by back-up ring, makes coupling bar 5 to move with pull bar 6, can rotate mutually between them simultaneously.Wherein, sliding pin 2 not only is used to connect driven pulley 3, axle 4 and coupling bar 5, and is used to bear additional shear stress.
Operating principle of the present utility model is: during use, gear clutch is fixed on the housing 15 by end cap 1 and end cap 2 10, when low seam mining machinery rocking arm operate as normal, gear clutch is in " closing the position " state (as shown in Figure 1), power is by driving wheel 1 input, and driving wheel 1 drives driven pulley 3 rotations by clutch spline 14, and power is by driven pulley 3 outputs, simultaneously, axle 4 and coupling bar 5 rotate with driven pulley 3 under the effect of sliding pin 2; When the start and stop of low seam mining machinery rocking arm or when being subjected to shock loading, produce speed difference between driven pulley 3 and the axle 4, impact thereby sliding pin 2 produced, make sliding pin 2 bear additional shearing force, cause fracture.And in the utility model owing between axle 4 and driven pulley 3, be provided with dive key 12, dive key 12 places the keyway of axle 4, then dive key 12 is static with respect to axle 4, dive key 12 moves with respect to driven pulley 3, bear additional load by dive key 12,2 of the sliding pins of this moment play anastomosis, have avoided being cut off by shock loading, have therefore improved the functional reliability of gear clutch greatly.
When needs are changed the duty of gear clutch, back out dog screw 8, draw-out handle 7 also revolves it to turn 90 degrees, the dog screw 8 of screwing on again, then gear clutch is in " offing normal " state, when handle 7 is drawn out, driven pulley 3 is drawn out by sliding pin 2, coupling bar 5 and pull bar 6, at this moment driving wheel 1 and driven pulley 3 separate, as want to allow gear clutch get back to " closing the position " state, only need reverse operating to get final product.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment did, all still belong in the protection domain of technical solutions of the utility model.
