Its structure is as shown in figures 1 and 3: mechanical speed reducing driving device mainly by mechanical reduction driving wheel and driven the wheel (or Road wheel) form, wherein the mechanical reduction driving wheel is to be enclosed within on the deceleration axle 3 by ratio wheel overcoat 1, at the ratio wheel overcoat 1 and deceleration axle 3 between lining nylon bush 2, deceleration axle 3 one ends are put into fixed mount 4 usefulness flat shims 5, spring shim 6, fastening nut 7, and the other end is that anti-off-gear is protected mechanical reduction driving wheel 8 of step formation; With mechanical reduction driving wheel 8 Be contained in driven take turns 13 and high speed machine power 9 with on the power transmission shaft 11 between the driving-belt connection for transmission wheel 10, machinery subtracts The ratio wheel of speed driving wheel and the driving gear (or anti-slop serrations) 12 of driven wheel the (or road wheel) 13 are nibbled to join and are formed (referring to figure 3).

Mechanical speed reducing driving device divides the mechanical reduction driving wheel that single head is fixing and double end is fixing, single head solid mechanical retardation gear The deceleration axle 3 of driving wheel is put into fixed mount 4 one ends and is tightened with flat shim 5, spring shim 6, nut 7, and the other end is to exceed Anti-ratio wheel overcoat 1 protects step (referring to Fig. 1) with the gear that nylon bush 2 is deviate from; And double end solid mechanical reduced speed drive wheel The two ends of deceleration axle 3 all put into fixed mount 4, get final product (referring to Fig. 2) with flat shim 5, spring shim 6, nut screwing clamping, Be contained in then driven take turns and high speed machine power 9 drives on the power transmission shaft 11 between the drives 10, mechanical reduction drives The ratio wheel of wheel cooperates with driven driving gear of taking turns.

The mechanical reduction drive unit requires the rotating speed of deceleration and the needs of speed per hour according to various machineries at a slow speed, can adorn the mechanical reduction driving wheel of 2 to 6 ratio wheels, on transmission shaft, can adorn into coaxial friction speed, single, double, three, 4 wheel driven is moving, friction speed drives mechanical reduction driving wheel.The ratio wheel of mechanical reduction driving wheel be driven that wheel (or road wheel) is trapezoidal, circular, the driving gear of peach shape, blade-shaped can both mate and nibble, so just can realize the purpose of this utility model.

Its working principle is referring to Fig. 3, mechanical reduction driving wheel 8 is contained in is driven wheel 13 and is connected on the transmission shaft 11 between the drive wheel 10 with driving belt with high speed machine power 9, the ratio wheel of mechanical reduction driving wheel is nibbled with the driving gear 12 that is driven wheel (or road wheel) 13, when power at a high speed 9 drives drive wheel 10, the ratio wheel of the mechanical reduction driving wheel 8 on the transmission shaft 11 of drive wheel, nibble the driving gear 12 that is driven wheel (or road wheel) 13, just can reach deceleration and drive the purpose of machinery at a slow speed.

Embodiment 1, is the fixedly two mechanical reduction driving wheels that drive of dual-side of single head, is used on the two-wheel miniature multi-function tiller, and working principle is with the described (see figure 4) of Fig. 3;

Embodiment 2, are the fixing positive single mechanical reduction driving wheels that drives of double end, are used on single-wheel miniature multi-function tiller, smelting ore deposit mechanical ball grinding machine and working machine dryer, the buffing machine, and working principle is with the described (see figure 5) of Fig. 3;
