Abstract

The utility model discloses a novel pattern decelerator, which belongs to a mechanical decelerator rotation shaft, and the decelerator comprises a turbine and a scroll. A reinforced rib is arranged in a turbine of the utility model, a poking strip is arranged on a drive plate, grooves of a cushion rubber ring whose two sides are crossingly opened with grooves are respectively embedded on the reinforced rib and the poking strip, the decelerator is led to have shock resistance, and torque ability is improved, an oil and copper pregnant bearing is mounted on a rotation shaft of a generator, relative positions of the turbine and the scroll are adjusted by adjusting screws, and impact noise is effectively controlled. The utility model has the advantages of reasonable structure design, extremely convenient installation or adjustment, impact resistance and long service life.

Description

New type speed reducer

Technical field

The utility model belongs to mechanical deceleration device, particularly a kind of stable drive, impact-resistant new type speed reducer.

Background technique

Present mechanical deceleration device has the diameter by two belt pulleys recently to slow down, and the dependence gear ratio that also has changes and slows down, and effect is relatively good, but with very stiff and demanding, no damping device, speed change tooth impact resistance is affected, rotational noise is big, and parts are vulnerable to damage.

Summary of the invention

The purpose of this utility model provides a kind of new type speed reducer, it is characterized in that: the rubber buffer ring 9 of the staggered fluting 18 in two sides, pad is between the driver blade 10 that the turbine 8 and the two sides band of inside band muscle 17 are dialled bar 20, be with bearing 7 in the central shaft hole 18 of turbine 8, pack in the deceleration box 6, after octadentate coupling shaft 1 puts oil sealing 2, pad 3, pass bearing 7 endoporus, turbine 8, buffer ring 9 and driver blade 10, waterproof oil sealing 11 are fixed together, on octadentate coupling shaft 1, twist and be buckled on the deceleration box 6 by mezzanine 13 with waterproof oil sealing 11 lock rings for C type clasp.

Pad is gone up waterproof apron 14 in the described deceleration box, and the rotating shaft 23 of inserting motor 5, speed change gear 22 and oil-containing copper bearing 15 are fixed on appropriate location on the machine shaft 23, by adjusting the occlusal position that screw 16 is adjusted in speed change gear 22 and turbine 8 on the machine shaft 23.

The staggered fluting 18 in described rubber buffer ring 9 two sides, one side is stuck on the muscle 17 of turbine 8, and another side is enclosed within dialling on the bar 20 of driver blade 10.

The beneficial effect that the utility model reaches 1. is decided by the structure of turbine buffering apron and driver blade, and the force intensity that is subjected to of turbine is increased, and improved and changeed apart from ability, and stability of rotation, impact resistance is strong; 2. on transverse axis, increase oil-containing copper bearing, make its rotation more steady, just controlling, reversing the impact noise that causes effectively; 3. on the deceleration box importing bulge loop is set, is connected rapidly easily dress with motor, precise and stable.

Fig. 1 is new type speed reducer profile schematic representation;

Fig. 2 is the BB sectional view of Fig. 1;

Fig. 3 is the AA sectional view of Fig. 1;

Fig. 4 is that each other part of Fig. 1 is assembled schematic representation.

Embodiment

Fig. 1 is new type speed reducer profile schematic representation.Retarder box 6 is linked together by screw 4 with motor 5, after the octadentate coupling shaft 1 of retarder puts oil sealing 2 and pad 3, insertion is fixed on turbine 8 center holes 18 inner bearings 7, and turbine 8 rubber buffer rings 9, driver blade 10 and waterproof oil sealing 11 be chained together, C type clasp 12 is with waterproof oil sealing 11 bandings (as shown in Figure 2) on octadentate coupling shaft 1.

Figure 3 shows that the structural representation of new type speed reducer, fix either ratio gear 22 in the rotating shaft 23 of motor 5, put square water proof rubber pad 14 on the motor end face after, in the deceleration box 6 of packing into, fixing by screw 4.Tooth 21 interlocks of the tooth of its speed change gear 22 and turbine 8, the fixing oil-containing copper bearing 15 in the motor bearings termination, its cylindrical has tooth, contact well with deceleration box 6, make motor shaft 23 stability of rotation, adjust the appropriate location of speed change gear 22 and turbo tooth 21 with adjusting screw 16, can just control effectively, impact noise during reverse, increase the impact resistance of between cog, rubber buffer ring 9 slots 19 alternately for the two sides, respectively with the muscle 17 of turbine 8 and driver blade 10 dial bar 20 embedding mutually, reduced retarder work effectively to the impact that turbine 8 is subjected to, prolonged working life (as shown in Figure 4).

Figure 4 shows that the part assemble sequence reference drawing in addition of new type speed reducer, the relative position between other part, the existing narration in front sees also.
