Abstract
The utility model relates to a three-pivot reduction gearbox and belongs to the technical field of electric fork lift trucks. The reduction gearbox comprises a reduction gearbox body, a primary gear pair and a secondary spiral bevel gear pair, and is characterized in that the reduction gearbox body is internally provided with the primary gear pair and the secondary spiral bevel gear pair; a driving gear is directly installed on a motor output shaft; and after connected with the reduction gearbox, the driving gear is meshed with the driven gear inside the reduction gearbox and output through a pair of spiral bevel gears. With small and flexible appearance, low noise, convenient operation and small turning radius, the reduction gearbox is widely applied to places such as light industry enterprises of food, electronic products and paint and the like, supermarkets, stations and the like.
Description
Technical field
The utility model relates to a kind of speed reducer, especially a kind of three fulcrum speed reduceres that are applicable to electric stacker.
Background technique
As everyone knows, three present fulcrum type electric motor cars are little with its vehicle body, from heavy and light, pollution-free, noise is little, easy to operate, radius of turn is little, can be in the operation in the throat and the confined space, have that height hoists, high bearing capacity, radius of turn is little, is the ideal tools of logistics system such as loading and unloading and stacking in warehouse, supermarket, the workshop.But unreasonable structure such as its gearbox volume is still big, reduction gear and roller bearing make that the gearbox radius of turn is big, and damage is arranged during gearbox, make three fulcrum type electric vehicle performances influenced.
Summary of the invention
In order to overcome the deficiency of existing three fulcrum type electric motor car gearboxes, the utility model provides that a kind of gearbox volume is littler, internal structure science, rationally more, and radius of turn is littler, non-damageable three fulcrum speed reduceres.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of three fulcrum speed reduceres, comprise speed reducer casing, gear, gear shaft, bearing and fixedly connected and encapsulation fitting, it is characterized in that: the secondary and deuterostrophies umbrella gear pair of primary cylinder gear is housed in the speed reducer casing;
The primary cylinder gear pair is by output shaft, flat key, driven gear, self-locking nut, driving gear is formed, and driving gear directly is contained on the motor output shaft, after speed reducer is connected, driven gear in driving gear and the speed reducer casing is meshed, and driven gear is fixed on the output shaft by flat key, self-locking nut;
Deuterostrophies umbrella gear pair is by spiral bevel gear, output shaft, tapered roller bearing, expose the matrix type oil sealing, circlip for hole, circlip for shaft, deep groove ball bearing is formed, the power of motor output is sent to output shaft by the primary cylinder gear pair, and output shaft and spiral bevel gear engagement are exported by spiral bevel gear again.
Above-mentioned described a kind of three fulcrum speed reduceres is characterized in that: spiral bevel gear is fixed in the speed reducer casing by a pair of deep groove ball bearing of arranging back-to-back.
The beneficial effects of the utility model are, are sent to driving gear because motor output shaft rotatablely moves to connect by flat key, and driven gear is by slowing down with the driving gear engagement.Driving gear is sent to output shaft by the flat key connection with power, and power is exported in output shaft and spiral bevel gear engagement.Speed reducer efficient height, scientific and reasonable for structure, simpler, radius of turn is littler, and working service is convenient.Be particularly useful for the three fulcrums series electric stacker below 1.5 tons.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure, 1. speed reducer casing, 2. spiral bevel gear, 3. output shaft, 4. tapered roller bearing, 5. flat key, 6. driven gear, 7. self-locking nut, 8. driving gear, 9. expose the matrix type oil sealing, 10. circlip for hole, 11. circlips for shaft, 12. deep groove ball bearings, 13. the primary cylinder gear pair, 14. deuterostrophies umbrella gear pairs.
Embodiment
Embodiment one
Referring to Fig. 1, embodiment one of the present utility model is WH02 small-sized electric forklift three fulcrum speed reduceres, comprises speed reducer casing 1, spiral bevel gear 2, output shaft 3, tapered roller bearing 4, flat key 5, driven gear 6, self-locking nut 7, driving gear 8 exposes matrix type oil sealing 9, circlip for hole 10, circlip for shaft 11, deep groove ball bearing 12, primary cylinder gear pair 13, deuterostrophies umbrella gear pair 14.
Primary cylinder gear pair 13, by output shaft 3, flat key 5, driven gear 6, self-locking nut 7, driving gear 8 is formed, and driving gear 8 directly is contained on the motor output shaft, and after speed reducer was connected, driving gear 8 and speed reducer casing 1 interior driven gear 6 was meshed; Driven gear 6 is sleeved on the output shaft 3 by flat key 5, again with self-locking nut 7 driven gear 6 and output shaft 3 fix;
Deuterostrophies umbrella gear pair 14 is by spiral bevel gear 2, output shaft 3, tapered roller bearing 4 exposes matrix type oil sealing 9, circlip for hole 10, circlip for shaft 11, deep groove ball bearing 12 is formed, and adopts a pair of tapered roller bearing 4 supportings on the output shaft 3, and locked fixing with self-locking nut 7, output shaft 3 and spiral bevel gear 2 engagements, power are at last by spiral bevel gear 2 outputs; Spiral bevel gear 2 is by a pair of deep groove ball bearing of arranging back-to-back 12 supportings; The spacing of deep groove ball bearing 12 finished by circlip for shaft 11 and circlip for hole 10, has the matrix type of exposing oil sealing 9 to reach sealing effect in its outside.
The utility model working principle
Motor output shaft rotatablely moves and is sent to driving gear 8 by the flat key connection, driven gear 6 is by slowing down with driving gear 8 engagements, driven gear 6 is sent to output shaft 3 by the flat key connection with power, and output shaft 3 outputs to main frame to power with spiral bevel gear 2 engagements.
