Description

Eight floor grinding mill gear-boxes

Technical field

The utility model relates to the grinder for stone mechanical device, and what be specifically related to is a kind of eight floor grinding mill gear-boxes.

Background technology

Running up of the driving-belt rotary bistriques at different levels of floor grinding mill dependence gear-box reaches work such as different stone surface finishings, polishings, so the good and bad operating efficiency that directly has influence on floor grinding mill of gear-box.

Have traditional floor grinding mill gear-box now and mainly comprise, case lid, casing, driving gear and driven gear etc., traditional gear-box only have the output of four statures, and operated motor is many, and transmission is not steady, and shake is severe, operation is wasted time and energy, and work area is little, the shortcomings such as inefficiency.

Summary of the invention

The purpose of this utility model is for the deficiencies in the prior art, and a kind of eight floor grinding mill gear-boxes are provided, and this gear-box has increased work area, and reduces the installation of motor.

The utility model is achieved through the following technical solutions: eight floor grinding mill gear-boxes, mainly be comprised of casing, the active oblique gear axle that is located at the casing centre, the active oblique gear of being located at the active oblique gear axle and driven gear transmission mechanism, this driven gear transmission mechanism is to be symmetrically distributed in the both sides of active oblique gear and the transmission that is meshed with active oblique gear respectively.

Described driven gear transmission mechanism is to be made of intermeshing between four driven bevel pinions and four the driven large helical gears; The driven gear transmission mechanism is to be made of intermeshing between four driven bevel pinions and four the driven large helical gears, the active oblique gear axle is positioned at the casing middle part and drives two driven bevel pinions, and two driven bevel pinions drive two driven bevel pinions and two driven large helical gears, drive two driven bevel pinions and two driven large helical gears by two driven bevel pinions again.

Preferably, described driven gear transmission mechanism also can be to be made of intermeshing between six driven bevel pinions and four the driven large helical gears; The active oblique gear axle is positioned at the casing middle part and drives two driven bevel pinions, and two driven bevel pinions drive two driven bevel pinions and two driven large helical gears, and four driven large helical gears drive four driven bevel pinions; Four driven bevel pinions drive four driven bevel pinions, and four driven bevel pinions drive four driven large helical gears.

Be respectively equipped with output shaft on the described driven large helical gear, this output shaft stretches out respectively the outside of casing lower end.

The beneficial effects of the utility model embody and are: compared with prior art, this gear-box namely can be installed eight bistriques and work simultaneously because eight output shafts are arranged, and its board work area is large, and operating personnel's operating efficiency improves greatly.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is the utility model embodiment one gear flat distribution map.

Fig. 2 is the utility model embodiment one STRUCTURE DECOMPOSITION figure.

Fig. 3 is the utility model embodiment two gear flat distribution maps.

Fig. 4 is the utility model embodiment two STRUCTURE DECOMPOSITION figure.

Classify down the concrete title of each sign among the figure as: 1 cover plate, 2 active oblique gear axles, 3 active oblique gears, 4 driven bevel pinions, 5 output shafts, 6 driven large helical gears, 7 casings.

The specific embodiment

As shown in Figures 1 and 2, eight floor grinding mill gear-boxes, mainly be comprised of cover plate 1, the active oblique gear axle 2 that is located at casing 7 centres, active oblique gear 3 and the driven gear transmission mechanism of being located on the active oblique gear axle 2, this driven gear transmission mechanism is to be symmetrically distributed in the both sides of active oblique gear 3 and the transmission that is meshed with active oblique gear 3 respectively.

Described driven gear transmission mechanism is to be made of intermeshing between four driven bevel pinions 4 and four the driven large helical gears 6.

Be respectively equipped with output shaft 5 on the described driven large helical gear 6, this output shaft 5 stretches out respectively the outside of casing 7 lower ends.

Such as Fig. 1 and Fig. 2, the transmission process of said gear case is: active oblique gear axle 2 is positioned at casing 7 middle parts and drives two driven bevel pinions 4, and two driven bevel pinions 4 drive two driven bevel pinions 4 and two driven large helical gears 6, drive two driven bevel pinions 4 and two driven large helical gears 6 by two driven bevel pinions 4 again, realize the motionless transmission that the output of eight statures is arranged of casing, and can change by gear rotation direction (left-handed and dextrorotation) direction of rotation of output shaft.

As shown in Figures 3 and 4, the driven gear transmission mechanism is to be made of intermeshing between six driven bevel pinions 4 and four the driven large helical gears 6.

Such as Fig. 3 and Fig. 4, the transmission process of gear-box is: active oblique gear axle 2 is positioned at casing 7 middle parts and drives two driven bevel pinions 4, two driven bevel pinions 4 drive two driven bevel pinions 4 and four driven bevel pinions 4 of 6, four driven large helical gears 6 drives of two driven large helical gears; Four driven bevel pinions 4 drive four driven bevel pinions 4, four driven bevel pinions 4 drive four driven large helical gears 6, thereby realize the motionless transmission that the output of eight statures is arranged of casing, and change the output shaft direction of rotation by gear rotation direction (left-handed and dextrorotation).
