Abstract

The utility model discloses a speed changing box of a pearl tea drying machine, which belongs to the field of the component of equipment processing tea leaves. The inner part of a box body is fixed with a first axle, a second axle and a third axle. A small gear and a big gear are respectively fixed on corresponding axles according to a speed changing structure, both ends of each axle are respectively sheathed with bearings and the outside of the bearings is additionally provided with an oil seal cover. After the utility model uses the bearings, gaps among the three axles and the bearings are proper, load stress is uniform and rotation is stable.

Description

The gearbox of green tea roasting machine

Technical field:

The utility model belongs to the components range of tealeaves making equipment, particularly a kind of gearbox of green tea roasting machine.

Background technique

Green tea roasting machine on the market mainly contains two kinds of models at present: 6CC-84 type two pot green tea roasting machine and the two pot of workers and peasants 84A type green tea roasting machine.The part of the gearbox the inside of 6CC-84 type green tea roasting machine is many and complicated.Part is many, and the gap causes the flight pendulum angle of green tea roasting machine not reach 90 degree between the part, influences green tea circularity.The part of this model green tea roasting machine is expensive, and maintenance is inconvenient again.Workers and peasants 84A type green tea roasting machine gearbox the inside simple structure is by two gearwheels of a pinion drive, again by three gearwheels of two pinion drive.Because what assemble on three the bearing hole is the sintered alloy lining, it with three to contact the working surface gap big, cause three axial floats and violent radial run-out, the load discontinuity, friction factor is big, generation is acutely beated and is caused:

1, lining is very easy to wear and tear and breaks.

2, three wear and tear easily, break.

3, crank arm dish and the contacting point of connecting rod that is contained in three two is very easy to badly, and the dish of cranking arm also can rupture with connecting rod.

4, sealing is bad between lining and the axle, and oil leakage phenomenon is more serious, and a machine will waste more than 20 kilogram of gear oil in 1 year.

5, three the play of beating, vibrate causes two small gears and the engagement of three gearwheels inhomogeneous, and concentrated wear is big.

Summary of the invention:

The purpose of this utility model provides a kind of gearbox of green tea roasting machine.One 1, two 4, three 5 of casing 10 internal fixation, small gear 2 and gearwheel 3 are fixed on the corresponding axle separately by speed changing structure, it is characterized in that: upper bearing (metal) 6 is overlapped at the two ends at one 1, two 4 and three 5 respectively, add charge of oil capping 7 at bearing 6, fast pulley 9 on one 1 axle that stretches out casing outside fixedly is cranked arm on three 5 axles that stretch out the casing outside and is coiled 8.

The beneficial effects of the utility model are: after adopting bearing, the gap is suitable between three and the bearing, not friction, and it is stressed even load, stability of rotation, thereby have the following advantages:

1, after the sintered alloy lining changed bearing into, damaging can not appear in bearing.

2, three can not produce wearing and tearing, break.

3, the dish of cranking arm contact working surface and weares and teares and can reduce 90% with connecting rod, increases the service life to greatest extent, and also can not producing cranks arm coils or connecting rod cracking.

4, because three rotation uniform and stable add the charge of oil capping at bearing, the gear oil that splashes in the gearbox behind three arrival bearings, just can not spill from oil sealing, has both saved oily money, has improved tea processing factory again by the situation that spills the gear grunge pollution to make dirty.

5, two small gears and three gearwheels even stability of rotation of loading, friction factor is little, prolongs their working life.

6, save engineering time and maintenance expenses to a great extent.

Fig. 1 is the gearbox sectional arrangement drawing of the utility model green tea roasting machine.

Fig. 2 is the gearbox appearance assumption diagram of the utility model green tea roasting machine.

Embodiment:

The utility model provides a kind of gearbox of green tea roasting machine, in the gearbox designs schematic representation of Fig. 1, green tea roasting machine shown in Figure 2, one 1, two 4, three 5 of casing 10 internal fixation, small gear 2 and gearwheel 3 are fixed on the corresponding axle separately by speed changing structure.Upper bearing (metal) 6 is overlapped at two ends at one 1, two 4 and three 5 respectively, adds charge of oil capping 7 at bearing 6, and fast pulley 9 on one 1 axle that stretches out casing outside fixedly is cranked arm on three 5 axles that stretch out the casing outside and coiled 8.

Claims

1, a kind of gearbox of green tea roasting machine, in (1), two (4) of casing (10) internal fixation, three (5), small gear (2) and gearwheel (3) are fixed on the corresponding axle separately by speed changing structure, it is characterized in that: overlap upper bearing (metal) (6) respectively at the two ends of (1), two (4) and three (5), add charge of oil capping (7) at bearing (6), stretch out the axle of casing outside one (1) and go up fast pulley (9), stretch out the axle of casing outside three (5) and go up the dish (8) of fixedly cranking arm.
