Abstract

The utility model discloses a spiral bevel gear reducer for an elevator, which comprises a case. An output shaft is disposed at the inner left end of the case, a large spiral gear is disposed on the output shaft, a gear shaft is disposed in the center of the case, a large bevel gear and a small spiral gear are formed on the gear shaft, and the small spiral gear is meshed with the large spiral gear. A bevel gear shaft is disposed at the inner right end of the case, a small bevel gear is formed at the left end of the bevel gear shaft, and the small bevel gear is meshed with the large bevel gear. The spiral bevel gear reducer is high in transmission efficiency commonly ranging from 92% to 95%, energy-saving and emission-reducing, cost is saved by above 35%, temperature rise is low, frictional wear is small, service life of an oil seal is long, and oil leakage rate is reduced greatly.

Description

Elevator is used the spiral bevel gear reductor
Technical field
The utility model belongs to a kind of reductor, is specifically related to a kind of elevator and uses the spiral bevel gear reductor.
Background technology
The elevator special reduction gear is a vitals on the building hoist, in construction, drives the elevator up-and-down movement with it, transports staff and building materials etc.; For these reasons, it is big that it requires this reductor to have a load-carrying capacity, compact conformation; Driving efficiency is high; Running is steady, and noise is low, plurality of advantages such as long service life.
But what the reductor major part of using on the building hoist at present adopted is the reductor of drive structure of gear worm, although this reductor is widely used at present; Performance meets the demands basically; But it has a lot of shortcomings: (ⅰ) driving efficiency is low, generally 72%~80%, have below 70%.(ⅱ) serious wear, the interior temperature rise of case is too high, reaches more than 80 ℃ in the temperature rise in summer, because temperature rise is too high, the seal ring distortion is rotten, loses sealing function, oil leakage phenomenon is very seriously.(ⅲ) consumption of current is big, cost is high, social benefit and low in economic efficiency.
Summary of the invention
The utility model proposes for the shortcoming that overcomes the prior art existence, and its objective is provides a kind of elevator to use the spiral bevel gear reductor.
The technical scheme of the utility model is: a kind of elevator is used the spiral bevel gear reductor, comprises casing, is provided with case lid at the left end of casing, is provided with stifle in the left lower end of casing, is provided with right end cap at the right-hand member of casing.
Left end is provided with output shaft in the inside of casing; Output shaft is provided with large helical gear, is provided with gear wheel shaft at the bosom of casing, and the two ends of gear wheel shaft are supported by No. two tapered roller bearings; On gear wheel shaft, form large bevel gear and bevel pinion, bevel pinion and large helical gear engagement.Right-hand member is provided with angular wheel shaft in the inside of casing, and angular wheel shaft is supported by three, No. four tapered roller bearings, in left end formation bevel pinion, bevel pinion and the large bevel gear engagement of angular wheel shaft.
On described output shaft, also be respectively arranged with tapered roller bearing, output sleeve, No. five tapered roller bearings, oil sealings successively and pass through lid.Pass through lid and compress oil sealing.
The utility model driving efficiency is high, generally 92%~95%; Energy-saving and emission-reduction, cost reduce about 35%; Temperature rise is low, friction wear is little, the oil sealing life-span is long, reduces oil spill rate greatly.
Description of drawings
Fig. 1 is the section-drawing of the utility model elevator with the spiral bevel gear reductor.
Wherein:
1. casing; 2. case lid; 3. output sleeve; 4. stifle; 5. a tapered roller bearing; 6. No. two tapered roller bearings; 7. bevel pinion; 8. bevel pinion; 9. No. three tapered roller bearings; 10. No. four tapered roller bearings; 11. right end cap; 12. angular wheel shaft; 13. large bevel gear; 14. gear wheel shaft; 15. pass through lid; 16. output shaft; 17. oil sealing; 18. No. five tapered roller bearings; 19. large helical gear.
The specific embodiment
Below, with reference to accompanying drawing and embodiment the utility model elevator is elaborated with the spiral bevel gear reductor:
As shown in Figure 1, a kind of elevator is used the spiral bevel gear reductor, comprises casing 1, is provided with case lid 2 at the left end of casing 1, is provided with stifle 4 in the left lower end of casing 1, is provided with right end cap 11 at the right-hand member of casing 1.Left end is provided with output shaft 16 in the inside of casing 1; One end of output shaft 16 stretches out the outside of casing 1, on output shaft 16, is respectively arranged with tapered roller bearing 5, output sleeve 3, large helical gear 19, No. five tapered roller bearings 18, oil sealings 17 successively and covers 15 thoroughly.Cover 15 thoroughly and compress oil sealing 17.
Bosom at casing 1 is provided with gear wheel shaft 14, and the two ends of gear wheel shaft 14 are supported by No. two tapered roller bearings 6, on gear wheel shaft 14, form large bevel gear 13 and bevel pinion 7, bevel pinion 7 and large helical gear 19 engagements.
Right-hand member is provided with angular wheel shaft 12 in the inside of casing 1, and angular wheel shaft 12 is supported by three, No. four tapered roller bearings 9,10, at the left end formation bevel pinion 8 of angular wheel shaft 12, and bevel pinion 8 and large bevel gear 13 engagements.
Wherein, the skew bevel gear of bevel pinion 8 and large bevel gear 13 employing standards.
The working process of utility model is:
Power is by the right-hand member input of reductor; Electrical motor drives angular wheel shaft 12 through coupler (not shown); Rotate through bevel pinion 8 and large bevel gear 13 engagement driven gear axles 14 again; The final bevel pinion 7 that passes through rotates outputting power with large helical gear 19 engagement drive output shafts 16, and the drive elevator is done and pumped, in order to transport staff and building materials.
The utility model driving efficiency is high, generally 92%~95%; Energy-saving and emission-reduction, cost reduce about 35%; Temperature rise is low, friction wear is little, the oil sealing life-span is long, reduces oil spill rate greatly.
