Abstract
The utility model belongs to the technical field of the manufacture of a gear in a reduction gear box, particularly relates to a gear of a miniature AC permanent magnet motor reduction box. The speed reduction gear of the motor reduction box of the utility model is of an integral structure formed through integral connection, wherein a driving gear and a driven gear of a duplicate gear which belongs to the class of speed reduction gears are respectively of an integral structure, and the driving gear and the driven gear are connected into a whole and are formed by the foundry of powder metallurgy. Compared with the prior art, as the gear is formed by the foundry of powder metallurgy, the utility model simplifies assembly technique; at the same time, as the duplicate gear is integrally formed, the transmission strength of the gear is enhanced, and the error rate of a motor is lowered. An output gear adopts a material saving design, and reduces the consumption of raw materials; due to the technique of powder metallurgy, walls of inner holes of the gear are provided with micropore structures for adsorbing lubricating oil, and the inner holes and shafts of the gears which rotate in a corresponding way have the function of self lubrication for preventing the gear from being locked; the function of self lubrication of the powder metallurgy reduces the consumption of grease lubricant and cost.
Description
Technical field
The utility model belongs to the gear manufacturing technology field in the reduction gear box, particularly a kind of gear of small-sized AC magnetoelectric machine speed reducer.
Background technique
Gear is an indispensable vitals in the driving mechanism, the gear that generally uses is that copper or steel process by machine cut now, generally be turning split processing gear shaft and pinion stand, then gear shaft and pinion stand are assembled together, processing technology complexity not only, particularly the duplicate gear employing is overrided to form for two sections, make the assembly technology complexity, simultaneously because the gear that adopts copper or steel to make needs constantly lubricated, otherwise the easy locking of gear, reduced the working life of speed reducer, relative cost is also higher.
Summary of the invention
The purpose of this utility model provides a kind of reduction gear arrangement of motor reduction gearbox, and its technical problem that will solve is whole reduction gear, especially duplex reduction gear, the simplified processing process made.
The utility model adopts following technological scheme for achieving the above object: a kind of reduction gear arrangement of motor reduction gearbox, the gear shaft of described reduction gear and pinion stand are the overall structure that one links.
Reduction gear described in the utility model is a duplicate gear, and the driving gear of this duplicate gear and driven gear are the overall structure that one links.
The driving gear of duplicate gear described in the utility model and driven gear are the overall structure that is formed by powder metallurgy casting that one links.
The utility model compared with prior art has following advantage:
1, because gear is formed by the powder metallurgy casting, simplified assembly technology, when having reduced the rigger, reduced cost, simultaneously,, increased the transmission intensity of gear, reduced the rate of fault of motor because duplicate gear is one-body molded.
2, output gear has adopted the design of economical with materials, has reduced raw-material use, and compliance with environmental protection requirements has been saved cost.
3, use the technology of powder metallurgy to make the bore wall have microporous structure adsorpting lubrication oil, have self-lubricating function when bore and axle are relatively rotated, prevent the gear locking, the self-lubricating function of powder metallurgy, reduce the use of lubricating grease, reduced cost.

Embodiment
Describe specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1, the reduction gear arrangement of motor reduction gearbox of the present utility model, the gear shaft of its reduction gear and pinion stand are the overall structure that one links.
When reduction gear was duplicate gear, the driving gear 2-2 of this duplicate gear and driven gear 2-1 were the overall structure that is formed by powder metallurgy casting that one links.
As shown in Figure 2, be the specific embodiment that the utility model is used for exchanging the powder metallurgical gear reducing gear of reduction gear box synchronous machine.Comprise powder metallurgical gear 1, gear 2, gear 3 and gear 4, plastic rubber bracket 5, day board component 6, axle sleeve 7, output shaft 8 and wavy spring 9, the cooperation of output shaft 8 usefulness annular knurls is pressed in the gear 4, and day board component 6 is formed by being riveted on two pillars 10 on day plate and two sleeve pipes 11 that are enclosed within on the pillar.Gear 1 is in the same place with the rotor assembly casting, and power is exported by output shaft 8 by speed reducer.All adopted the powder metallurgy casting to form at this speed reducer middle gear, gear 2,3 is one-time formed duplicate gear.Adopt powder metallurgy and one-time formed duplicate gear can simplify assembly technology, improve transmission accuracy, reduce noise, also make the structure of speed reducer become compact simultaneously.
As shown in Figure 4, output gear 4 of the present utility model has adopted the design of the economical with materials of the equal portion of circumference through hole, has reduced raw-material use, and compliance with environmental protection requirements has been saved cost.Gear 1, gear 2, gear 3 and gear 4 have all adopted the powder metallurgy casting, have saved the cutting time, have increased intensity, have guaranteed the conformity of dimensional tolerance, thereby have reduced cost, have guaranteed quality.
The utility model uses the technology of powder metallurgy to make the bore wall have microporous structure adsorpting lubrication oil, have self-lubricating function when bore and axle are relatively rotated, prevent the gear locking, the self-lubricating function of powder metallurgy, reduce the use of lubricating grease, reduced cost.
The powder metallurgical gear that is used for the synchronous speed reducer motor of small-sized AC permanent-magnet rotor can also be applied in the AC synchronous reducing motor, as the motor that uses in the automatic mahjong-playing machine.
