Abstract

The utility model relates to a speed reducing mechanism of a food mixing machine. The utility model is driven by an electric motor. A worm fixed on the shaft of the electric motor is engaged with a worm wheel, which drive a gear 1 on a middle shaft. The gear 1 is engaged with a gear 2, which drive the center shaft. Both ends of the center shaft are respectively supported on a casing and a flange seat by bearings. The lower end of the center shaft is fixedly connected with a rotating disk. The utility model is characterized in that the middle shaft is a cantilever shaft, and one end of the middle shaft is fixed on the flange seat. The middle shaft is provided with a shaft sleeve, and both of the middle shaft and the shaft sleeve form into a rotary pair. The worm wheel and the gear 1 are fixed on the shaft sleeve.

Description

Speed reducing mechanism of food mixing machine

The utility model is a kind of improved food blending machine reducing gear.

Existing a kind of food blending machine is used motoring, slows down by worm and gear and gear mechanism, drives stirrer again and makes revolution and spinning motion.The intermediate propeller shaft of its reducing gear and central shaft, two ends are by the bearing supporting that is arranged on casing and the flange seat, and bearing hole position accuracy demand height is processed difficulty, and assembling and maintenance are inconvenient.

The purpose of this utility model is a shortcoming of avoiding above-mentioned food blending machine reducing gear, provides a kind of processing, assembling and maintenance to be easy to the food blending machine reducing gear.

Solution of the present utility model is, intermediate propeller shaft is designed to the cantilevered axle that an end is fixed in flange seat, establishes a sliding shaft sleeve on the cantilevered axle and forms the single-revolution pair with it, and driving component worm gear and gear are keyed on the axle sleeve.

Specify structure of the present utility model below in conjunction with accompanying drawing.

Fig. 1 is the driving mechanism sketch of existing food blending machine;

Fig. 2 is a unfolded drawing of the present utility model;

Fig. 3 is an assembling schematic representation of the present utility model;

Fig. 4 is that the A-A of Fig. 3 is to view.

Among the figure, (1) central shaft, (2) worm gear, (3) casing, (4a) intermediate propeller shaft, (4b) cantilever type jack shaft, (5) worm screw, (6) motor, (7) stirring shaft, (8) gear 3, (9) rotating disk, (10) internal gear, (11) flange seat, (12) gear 2, (13) gear 1, (14) axle sleeve, (15) key, (16) spacer, (17) back-up ring, (18) screw.

The driving mechanism of existing food blending machine, drive worm screw (5) by motor (6), worm screw (5) transmission worm gear (2) is together with intermediate propeller shaft (4a) and gear 1(13), gear 1(13) driving gear 2(12) together with central shaft (1) and rotating disk (9), rotating disk (9) drives stirring shaft (7) and gear 3(8), intermediate propeller shaft (4a) two ends are bearing in respectively on casing (3) and the flange seat (11) with bearing.Jack shaft of the present utility model is a cantilever type, and cantilever type jack shaft (4b) is with stationary fit or be threaded and be fixed on the flange seat (11), with shaft shoulder axially locating; One axle sleeve that is slidingly matched with it (14) is arranged on the cantilever type jack shaft (4b), form a rotary pair; Axle sleeve has keyway on (14), with key (15) worm gear (2) and gear 1(13) be fixed on the axle sleeve (14), axle head limits axle sleeve (14), worm gear (2) and gear 1(13 with back-up ring (17) and screw (18)) move axially; Be shaped on radial direction through hole on spacer (16) and the axle sleeve (14), the slip surface that grease is entered between cantilever type jack shaft (4b) and the axle sleeve (14) is lubricated.This structure of jack shaft equally also can be used for two grades of reduction gears mechanisms of food blending machine.

Claims

1, a kind of food blending machine reducing gear, use motoring, be fixed on worm screw (5) and worm gear (2) engagement on the motor reel, drive the gear 1 (13) on the jack shaft (4b), gear 1 (13) and gear 2 (12) engagements, drive central shaft (1), the two ends of central shaft (1) are bearing in respectively on casing (3) and the flange seat (11) by bearing, the affixed rotating disk in central shaft (1) lower end (9), it is characterized in that: jack shaft (4b) is cantilevered axle, and an end is fixed on the flange seat (11), and axle sleeve (14) is arranged on the jack shaft (4b), both form rotary pair, and worm gear (2) and gear 1 (13) are fixed on the axle sleeve (14).
