In addition, the motor reducing mechanism is compact in arrangement, small in size and high in reducing stability.

Description

Motor decelerating mechanism

Technical field

The utility model relates to a kind of motor, relates in particular to a kind of motor decelerating mechanism.

Background technique

Speed reducer is that a kind of power is passed on mechanism, utilizes the velocity transducer of gear, the winding number of motor is decelerated to desired winding number, and obtain the mechanism of big torque.Be used for the mechanism of transferring power and motion at present; The application area of speed reducer is quite extensive, almost in the transmission system of various machinery, can see its trace, from boats and ships, automobile, the locomotive of the traffic tool; Heavy facility for building; Machining machine and tool that mechanical industry is used and automated production equipment, common household electrical appliances in the daily life, clock and watch or the like; It uses the transmission work from big power, and to little load, accurate angle transmission can be seen the application of speed reducer, and on commercial Application, speed reducer has deceleration and increases the torque function, therefore is widely used in the conversion equipment of speed and moment of torsion.At present, not only part is many, volume is big for the reducing gear on the market, drive mechanism is complicated, and its cost of production is high, and rate of fault is high, safeguard inconvenient, to the user caused many not time.

The model utility content

The purpose of the utility model is to the problems referred to above a kind of motor decelerating mechanism to be provided, and existing motor decelerating mechanism volume is big, drive mechanism is complicated, cost of production is high to solve, safeguard inconvenient problem.

The purpose of the utility model is to realize through following technological scheme:

A kind of motor decelerating mechanism; Comprise casing, the case lid that matches with casing and be arranged at the reduction gears mechanism in the casing; Said reduction gears mechanism comprises one-level tooth axle, secondary tooth axle, three grades of tooth axles and level Four tooth axle, on the tooth axles at different levels driving gear is installed all, and the tooth on the tooth axle at different levels is meshed with driving gear on the one-level tooth axle thereafter; The driving gear of said one-level tooth axle and the engagement of the tooth on the motor output shaft, the tooth on the level Four tooth axle is meshed with the gear of reducing gear output shaft.

Further, the two ends of tooth axles at different levels are equipped with bearing, the mounting hole interference fit of offering on said bearing and casing, the case lid.

Preferably, said bearing is an oil-impregnated bearing.

Further, be symmetrically arranged with fixed hole on said casing, the case lid, and connect through screw.

Preferably, said screw is a Cross Recess Head Screw.

The beneficial effect of the utility model does, said motor decelerating mechanism has been realized the Pyatyi deceleration, promptly by the power of motor output shaft output after tooth shaft drive at different levels are slowed down; Outputed power by the reducing gear output shaft at last, it is simple in structure, be easy to realize, has reduced cost of production; And easy to maintenance, in addition, its compactness of arranging; Volume is little, the deceleration good stability.

Embodiment

Further specify the technological scheme of the utility model below in conjunction with accompanying drawing and through embodiment.

Please referring to figs. 1 through shown in 6; In present embodiment; A kind of motor decelerating mechanism comprises casing 7, the case lid 6 that matches with casing 7 and is arranged at the reduction gears mechanism in the casing 7, is symmetrically arranged with fixed hole on said casing 7, the case lid 6; And through the Cross Recess Head Screw fixed connection; Said reduction gears mechanism comprises one-level tooth axle 1, secondary tooth axle 2, three grades of tooth axles 3 and level Four tooth axles 4, and the two ends of tooth axles at different levels are equipped with oil-impregnated bearing 8, mounting hole 9 interference fit of offering on said oil-impregnated bearing 8 and casing 7, the case lid 6; And on the tooth axles at different levels driving gear 12 is installed all; Tooth on the tooth axles at different levels is meshed with driving gear 12 on the one-level tooth axle thereafter, the tooth engagement on the driving gear 12 of said one-level tooth axle 1 and the motor output shaft that is installed in the motor output shaft mounting hole of offering on the casing 7 10, the tooth on the level Four tooth axle 4 be installed on casing on the gear of the interior reducing gear output shaft 5 of reducing gear output shaft mounting hole 11 be meshed.

During work, the rotation of motor driving motor output shaft, driving gear 12 rotations on the moving one-level tooth axle 1 of the cingulum on the motor output shaft; Because driving gear 12 and one-level tooth axle 1 are connected through pin, the rotation of driving gear 12 drives one-level tooth axle 1 and rotates, and the driving gear 12 on the secondary tooth axle 2 that the tooth on the rotation drive of one-level tooth axle 1 and the one-level tooth axle 1 meshes rotates; And drive secondary tooth axle 2 rotations; Secondary tooth axle 2 drives 3 rotations of three grades of tooth axles thus, and three grades of tooth axles 3 drive 4 rotations of level Four tooth axle, tooth on the level Four tooth axle 4 and the gear engagement on the reducing gear output shaft 5; Drive 5 rotations of reducing gear output shaft, form the Pyatyi transmission.
