By adopting technique scheme, idle pulley has two kinds of operating modes, and energy transferring power when namely engaging respectively with first and second gear, when not engaging with first and second gear, the second gear does not rotate, and belt wheel only drives the first pinion rotation, realizes single cylinder work.
The utility model is set to further: described idle pulley comprises axle center, latch and engaging piece, casing is fixed on by bearing in described axle center, described latch is fixed on axle center, described engaging piece is provided with a through hole, described axle center is passed the through hole of engaging piece and is connected a locking nut, and there is the screw thread matched with described locking nut in described axle center, is provided with spring between described latch and described engaging piece, described latch has some projections, the groove that described engaging piece has described some projections corresponding.。
By adopting technique scheme, engaging piece is by fastening with latch under the effect of locking nut, and transferring power, the effect again by spring separates with latch.Spring makes engaging piece abut against on locking nut by extruding engaging piece simultaneously, prevents from because of Double-cylinder piston type air compressing machine vibration, locking nut being come off from axle center.
The utility model is set to further: be provided with pad between described locking nut and engaging piece.
By adopting technique scheme, when pad can rotate locking nut, driving the power of engaging piece axial motion to be distributed to uniformly on the whole end face of engaging piece, avoiding stress and concentrating damage engaging piece.
The utility model is set to further: described idle pulley and the described first gear number of teeth relatively prime, described idle pulley and the described second gear number of teeth relatively prime.
By adopting technique scheme, number of teeth material, except one no longer includes other common divisor namely, the frequency that periodic defect occurs can be reduced, avoiding individual defects to appear at identical wanting and position continually.
Compared with prior art, the beneficial effects of the utility model are: idle pulley has two kinds of operating modes, energy transferring power when namely engaging respectively with first and second gear, when not engaging with first and second gear, second gear does not rotate, and belt wheel only drives the first pinion rotation, realizes single cylinder work.Engaging piece is by fastening with latch under the effect of locking nut, and transferring power, the effect again by spring separates with latch.Spring makes engaging piece abut against on locking nut by extruding engaging piece simultaneously, prevents from because of Double-cylinder piston type air compressing machine vibration, locking nut being come off from axle center.Drive the power of engaging piece axial motion to be distributed to uniformly on the whole end face of engaging piece when pad can rotate locking nut, avoid stress and concentrate and damage and engaging piece.The number of teeth is relatively prime, except one no longer includes other common divisor namely, can reduce the frequency that periodic defect occurs, avoids individual defects to appear at identical wanting and position continually.

Embodiment
Referring to figs. 1 through Fig. 5, the embodiment of the utility model Double-cylinder piston type air compressor is described further.
A kind of Double-cylinder piston type air compressor, comprise crankcase 1, be fixed on the belt wheel 3 that bent axle in crankcase 1 and driving crank rotate, described bent axle has two, be respectively the first bent axle and the second bent axle, described first bent axle one end is stretched out crankcase 1 and is fixed with the first gear 4, first gear 4 and connects belt wheel 3.Described second bent axle one end is stretched out crankcase 1 and is fixed with the second gear 5, an idle pulley 8 is provided with between described first gear 4 and described second gear 5, described idle pulley 8 is movable and can be in primary importance and the second place, when being in primary importance idle pulley 8 respectively with described first gear 4, engage with described second gear 5, idle pulley 8 and described first gear 4 when being in the second place, do not engage with described second gear 5, described first gear 4 connects belt wheel 3.Described idle pulley 8 comprises axle center 8a, latch 8b and engaging piece 8c, described axle center 8a is fixed on casing by bearing, described latch 8b is fixed on the 8a of axle center, described engaging piece 8c is provided with a through hole, described axle center 8a passes the through hole of engaging piece 8c and connects a locking nut 6, described axle center 8a has the screw thread matched with described locking nut 6, is provided with pad 7 between described locking nut 6 and engaging piece 8c.Be provided with spring 9 between described latch 8b and described engaging piece 8c, described latch 8b has some projections, the groove that described engaging piece 8c has described some projections corresponding.Pad 7 is provided with between described locking nut 6 and engaging piece 8c.Described idle pulley 8 is relatively prime with described first gear 4 number of teeth, and described idle pulley 8 is relatively prime with described second gear 5 number of teeth.
When Double-cylinder piston type air compressor only needs a cylinder operation, unclamp locking nut 6, engaging piece 8c departs from first and second gear gradually and engages, when departing from completely under the effect of spring 9, just successfully realize single cylinder effect, now drive motor band movable belt pulley 3 works.
When Double-cylinder piston type air compressor needs two cylinders to work simultaneously, screw locking nut 6, engaging piece 8c is thought gradually, and latch 8b draws close, until completely and latch 8b fasten, now engaging piece 8c and first and second gears meshing, drive motor band movable belt pulley 3 works just can realize twin-tub action.
By adopting technique scheme, idle pulley 8 has two kinds of operating modes, energy transferring power when namely engaging respectively with first and second gear, and when not engaging with first and second gear, the second gear 5 does not rotate, and belt wheel 3 drives the first gear 4 to rotate, and realizes single cylinder work.Engaging piece 8c is by fastening with latch 8b under the effect of locking nut 6, and transferring power, the effect again by spring 9 separates with latch 8b.Spring 9 makes engaging piece 8c abut against on locking nut 6 by extruding engaging piece 8c simultaneously, prevents from because of Double-cylinder piston type air compressing machine vibration, locking nut 6 being come off from axle center 8a.Drive the power of engaging piece 8c axial motion to be distributed to uniformly on the whole end face of engaging piece 8c when pad 7 can rotate locking nut 6, avoid stress and concentrate and damage engaging piece 8c.The number of teeth is relatively prime, except one no longer includes other common divisor namely, can reduce the frequency that periodic defect occurs, avoids individual defects to appear at identical wanting and position continually.
