Abstract
The utility model relates to a four planet gear motor for a battery tricycle which is composed of a gear box and a direct current motor. A shaft tooth in the gear box is arranged on a shaft of the direct current motor, and the outer edge of the shaft tooth is engaged with four planet gears which are arranged at the angle of 90 deg, is connected with a same output shaft and is engaged with a peripheral inner tooth loop. The shaft tooth, the planet gear and the inner tooth loop are arranged in the same plane. When used, the battery tricycle of the four planet gear motor of the utility model has the advantages of stable running and bearing ability increase, and a gear motor is not easy to damage.
Description
The utility model relates to a kind of storage battery tricycle four lines star gear motor.
The storage battery tricycle is to be powered to storage battery tricycle motor by storage battery, produces drawing force by motor again and drags the storage battery tricycle, implements load-carrying and drags.Because the load of storage battery tricycle load-carrying is bigger, so storage battery tricycle motor must export bigger output torque and more moderate output speed, could satisfy the needs that the storage battery tricycle normally moves.Existing storage battery tricycle is to adopt three planet gear motors, has realized dragging storage battery tricycle cruising with the less bigger torque of motor output.This three planet gear motors, its gear box have three planetary gears, an axle tooth and a ring gear.See that theoretically determine a plane at 3, should be able to guarantee that three planetary gears mesh with axle tooth, ring gear simultaneously.But in fact, because Gear Processing has trueness error, the engagement between gear and the gear is not no sideshake, and therefore, in fact the operation of gear is to carry out having under the state of sideshake all the time.At this moment, if occur the gap when in three planetary gears a gears engaged being arranged, then the planetary engagement of other two operations forms an extremely unsettled line, cause tooth axle and axle tooth and ring gear to produce shake, make a planetary tooth in three planetary gears, give birth to bump and produce damage with the internal tooth and the axle tooth and hair of ring gear.Gear box damages quantity and accounts for about 70% of storage battery tricycle gear motor damage quantity, and most applications is only to have a planetary gear to be damaged in three planetary gears.Because China still belongs to developing country at present, economy is rich not enough, and is all the more so in rural area and outlying district.As the load-carrying Drag tool, domestic animal is adopted in early stage rural area, now is eliminated in most of areas, especially on the outskirts of a town joint portion, more because of its contaminated environment does not allow to use, and comparatively advanced load-carrying Drag tool---automobile, though there is use in the rural area, be subjected to economics dictate, popularize far away.Under this specific economic condition, the storage battery tricycle arises at the historic moment as a kind of economical free of contamination load-carrying Drag tool and becomes a kind of load-carrying Drag tool with linking effect.Along with the continuous improvement of China village economic state, the storage battery tricycle can be used widely in the fringe area in rural area from now on, and trend increasing and that expand to the west area is arranged.But the high spoilage of present this storage battery tricycle three planet gear motors has seriously hindered the development of storage battery tricycle.
The purpose of this utility model is, a kind of storage battery tricycle four lines star gear motor that increases stable degree of storage battery tricycle planetary gear and gear box load capacity is provided.
The technical scheme that realizes the utility model purpose is: a kind of storage battery tricycle four lines star gear motor, form by gear box and direct current machine, ring gear, planetary gear, axle tooth, output shaft are arranged in the gear box, axle tooth in the gear box is disposed on the motor shaft of direct current machine, axle tooth outer rim has to nibble establishes 4 planetary gears that are arranged in 90 °, these 4 planetary gears are connected on the same output shaft, and simultaneously with the internal tooth engagement of the ring gear of its periphery, axle tooth, 4 planetary gears and ring gear are configured in the same plane.
Technique effect of the present utility model is: 1. increased planetary row fortune smoothness, thereby reduced planetary damage.Storage battery tricycle four lines star gear motor of the present utility model, the inherent axle of its gear box tooth outer rim has 4 planetary gears to nibble to establish to be arranged in 90 °, simultaneously with the internal tooth engagement of the ring gear of its periphery, and axle tooth, 4 planetary gears and ring gear all are configured in the same plane.Therefore,, still have 3 planetary gears to form an operation plane, thereby carry out stable operation, can not cause tooth to clash into not to be damaged because of the tooth axle produces shake with tooth even when having an engagement not good in 4 planetary gears; 2. increased the load capacity of gear box.4 of gear motors of the present utility model are planetary stressed even, symmetrical, and actual the use shows, the direct current machine of equal-wattage disposes the torque force of 4 planetary gear box outputs, much larger than disposing 3 planetary gear boxes.Like this, the storage battery tricycle of use four lines star gear motor operates steadily, weight capacity increases, and is not fragile.
Embodiment below in conjunction with accompanying drawing provides is further described in detail storage battery tricycle four lines star gear motor of the present utility model.
The cutaway view of the structural representation of Fig. 1, the utility model storage battery tricycle four lines star gear motor;
4 planetary planar structure schematic diagrames of Fig. 2, four lines star gear motor of the present utility model;
Fig. 3, be 3 planetary planar structure schematic diagrames of three planet gear motors.
Shown in Fig. 1～2, storage battery tricycle four lines star gear motor of the present utility model is made up of gear box 5 and direct current machine 4, ring gear, planetary gear, axle tooth, output shaft are arranged in the gear box 5, axle tooth 3 in the gear box 5 is disposed on the motor shaft of direct current machine 4, axle tooth 3 outer rims have to nibble establishes 4 planetary gears 21,22,23 and 24 that are arranged in 90 °, these 4 planetary gears are connected on the same output shaft 6, and simultaneously with the internal tooth engagement of the ring gear 1 of its periphery, axle 3,4 planetary gears 21,22,23 of tooth and 24 and ring gear 1 be configured in the same plane.
Four lines star gear motor of the present utility model is assemblied in when using on the storage battery tricycle, behind the power supply that the direct current machine 4 of four lines star gear motor is accepted from storage battery, go rotating shaft tooth 3, axle tooth 3 drives 4 planetary gears 21 again, 22,23 and 25 row change, again through cooperate deceleration with ring gear 1 after, rotate through output shaft 6 shafts, the shaft rotating speed is slack-off, torque increases, and power of motor is increased, and has realized dragging the bigger storage battery of load-carrying three tricycles with the motor of smaller power, make it even running, even there is any planetary gear to damage, still keep 3 planetary gears and forming an operation plane, still can stable operation.Its load capacity exceeds about 1.34 times than three planet gear (referring to Fig. 3) motors, and under the same load, the motor spoilage reduces greatly.
