Abstract

The utility model relates to a miniature speed reducer matched with a snow-melting machine used for high-grade cold and hot drinks. The miniature speed reducer is composed of a shaded pole motor and a miniature multistage speed reducer. The key point of the technology lies in that an electromotor (2) and a reducer casing are connected organically and delicately. A second stage gear (12), a third stage gear (13), and a fourth stage gear (14) are adopted with a device of damping vibration of a cylindrical oil-retaining bearing and a rubber vibration damping ring. The speed reducer achieves the goal of low noise, large torque and no leakage through five-stage transmission and four-stage deceleration. The utility model matched with the snow-melting machine can always guarantee an operation with the advantages of long term, uniformity, low noise and no leakage. The miniature speed reducer has the advantages of simple structure, high credibility, low noise, sanitation, cleanness, etc.

Description

Micro-reducer

The utility model micro-reducer is a kind of novel practical speed reducer that motor with cup rotor combines with miniature special retarding case, is mainly used in snow and melts machine and stir and to drag.

It is the high-grade hot and cold drinking machine that had just risen in recent years that snow melts machine, and originally main several big cities municipalization relies on import always, at present domestic have many producers trial-production production snow to melt machine, critical component split-pole speed reducer wherein can not pass major defect: one, noise is big, (＞70dB (A)); The 2nd, torque little (＜3.2Nm); Three, damage easily, easy oil leakage in case it is also very difficult to damage maintenance, can not be satisfied snow and melt machine requirement in use.

In order to overcome above-mentioned shortcoming, satisfied snow melts machine requirement in use, and what the utility model designed a kind of low noise, high pulling torque, ne-leakage melts the matching used micro-reducer of machine with snow.

In order to realize above-mentioned target, it is new that technical thought of the present utility model is made following plane: (one) is in order to reduce the noise of speed reducer: 1,2. 4. speed reducer casing first order gear be connected in one with motor, second level gear (12), third level gear (13), fourth stage gear (14) rotate, adopt cylinder type copper base oil containing bearing (9), bearing outer ring supports as vibration damping with oil resistant rubber (7).2, first pair of gear adopts helical gear to rotate, and the driven gear of the second level (12), the third level (14) adopts the high-strength abrasion-proof nylon gear.(2) for leakage proof: 1, first order gear (4) input shaft is owing to the rotating speed height, and the motor heat transmits easily, and the utility model adopts the outside framework oil seal (3) that dual face seals is housed at output shaft.Adopt oil resistant rubber liner (11), prevent seepage.(3) for increasing output torque, guaranteeing suitably to reduce number of wire turns under the constant prerequisite of external dimension, add the thick line footpath, back axle head is equipped with plastic fan (1), forces the cooling channel device, suitably increases the modulus and the effective thickness of nylon gear.

The structure of micro-reducer of the present utility model, form by motor (2) and speed reducer two-part, its technical characteristics is that motor (2) links to each other with speed reducer first order gear (4), the second level (12), the third level (13) driven gear is the high-strength nylon gear, and first order gear (4), second level gear (12), third level gear (13), fourth stage gear (14), level V gear (15) the from bottom to top company of being arranged in order are dressed up the level Four deceleration.Speed reducer by speed reducer at the bottom of (6) and gear box cover (8) be located by connecting, sealing at the bottom of the speed reducer with between gear box cover contact, employing rubber bushing (11), the output shaft of half bond structure and level V gear (15) fuse.For reducing thermolysis, plastic fan (1) is housed on the axle of the rear end of shaded-pole motor.

The utility model micro-reducer has following advantage: one, this micro-reducer running noises is low, total noise of centrifuge≤57dB (A).Two, good airproof performance, ne-leakage oil phenomenon.Three, velocity ratio is big: the gear reduction velocity ratio reaches 66: 1.Motor and the casing compact structure that fuses, design optimization, noise is low, and velocity ratio is big, ne-leakage, is current and snow melts the matching used more satisfactory product of machine.

Fig. 1 is the structure sectional view of the utility model micro-reducer;

Sequence number among the figure: 1-fan; The 2-motor; The 3-seal ring; 4-first order gear; 5-high-strength nylon gear; At the bottom of the 6-speed reducer; 7-oil resistant rubber damping ring; The 8-gear box cover; 9-copper base oil containing bearing; 10 output shafts; 11 ,-rubber bushing; 12-second level gear; 13-third level gear; 14-fourth stage gear; 15-level V gear.

Nextpage is described further installation of the present utility model and using process in conjunction with Fig. 1: plastic fan (1) is installed in the rear end of motor (2), one-level gear (4) is linked by sieve cap with motor (2) shaft extension, oil resistant rubber damping ring (7) be installed in (6) at the bottom of the speed reducer, with the corresponding bearing hole of gear box cover (8) in, bearing (9) is installed in the rubber damping circle (7).First order gear (4), second level gear (12), third level gear (13), fourth stage gear (14), level V gear (15) from bottom to top are arranged in order connection, rubber shirt pad (11) is housed between two of (6) and gear box cover (8) at the bottom of the speed reducer is fastenedly connected by the Luo Ding location.Use of the present utility model is to melt machine the inside Lower Half by being installed in snow, and output shaft half bond (10) links to each other with stirrer and drives running.After motor is connected power supply, directly drag snow by speed reducer and melt the work of machine stirrer.
