Abstract

The utility model belongs to a motor, in particular to a high torque pneumatic gear motor used in collaboration with an anchor line jumbolter, and comprises a gear which is arranged in the motor housing and an inlet opening which is arranged on the top of the motor housing; wherein, the center of the gear is flexibly connected with the motor housing, and the centers of the two gears are in the same horizontal line. The middle of the bottom of the motor housing is vertically provided with a clapboard, and the under-part of the motor housing is connected with a muffler housing and the inner cavity of the motor housing is communicated with the inner cavity of the muffler housing, the upside of which is transversely provided with an anechoic layer which is composed of anechoic materials. The upside and the underside of the anechoic layer are provided with a wind-dissipating halftone, and the under-part of the muffler housing is communicated with an air outlet. The utility model solves the shortcomings of complex construction, multiple wind-cavities, difficult casting, large watt consumption, large volume of the muffler, a small air outlet and poor anechoic effect, thus having the advantages of simple structure, convenient manufacturing and processing, simple and compact structure of the muffler, small watt consumption during the processes of expansion and contraction of the air and low noise, etc.

Description

The large-torque pneumatic gear motor

Technical field

The utility model belongs to engine, is meant a kind of especially and the matching used large-torque pneumatic gear motor of Anchor cable-rod rig.

Background technology

The pneumatic roof bolter of existing domestic and international production at present is most of to be 50C type (being nominal torque 50Nm) or other modified, supporting with it gear motor is generally and is externally connected to silencer in above-mentioned existing equipment, after high-pressure blast enters from air inlet, after the driven gear rotation work done, the low-pressure air of volumetric expansion is circuitous through little air channel, shrink again in a little air outlet, by discharging after the noise reduction.Above-mentioned existing equipment exists complex structure, the wind chamber is many, is difficult for casting, and gas power consumption in the process that expands, shrinks volume big, silencer is big, air-out is young, shortcomings such as noise elimination weak effect.

Summary of the invention

The purpose of this utility model is to provide a kind of and the matching used large-torque pneumatic gear motor of Anchor cable-rod rig to overcome the deficiency of prior art.

Overall structure of the present utility model is:

The large-torque pneumatic gear motor, comprise the gear 2 that is arranged at respectively in the

motor shell

10,8, be opened in the air inlet 1 at motor shell 10 tops,

gear

2,8 center and motor shell 10 flexibly connect, being centered close on the same horizontal line of gear 2 and gear 8, motor shell 10 bottoms are vertically arranged with dividing plate 3, the lower vertical of motor shell 10 or be radial open wide and be connected with suppressor case 7, the inner chamber of suppressor case 7 is communicated with the wind chamber 4 of the bottom of motor shell 10, the upper lateral of suppressor case 7 is provided with the silencing plate of being made up of deadener 6, on the silencing plate 6, following both sides are provided with the wind web plate 5 that looses, and the bottom of suppressor case 7 is communicated with air outlet 9.

Concrete structure of the present utility model also has:

Dividing plate 3 bottoms or side and motor shell 10 are for fixedlying connected.

Suppressor case 7 and motor shell 10 are for fixedlying connected.

Suppressor case 7 sidewalls of diffusing wind web plate 5 bottoms offer air outlet 9.

The obtained technological progress of the utility model is:

Motor configuration of the present utility model is simple, is convenient to make, process, and acoustic wave filter structure is simple, compact, and gas power consumption in expansion, contraction process is little, and noise is low.

Description of drawings

Accompanying drawing of the present utility model has:

Fig. 1 is a structural representation of the present utility model.

Preferred forms

Below in conjunction with accompanying drawing embodiment of the present utility model is further described:

The overall structure of present embodiment as shown, wherein adopt the screw tight fit to be connected between suppressor case 7 and the motor shell 10, dividing plate 3 is connected with the integrated casting of the inner surface of motor shell 10, deadener is selected polyester form for use, air inlet 1 is opened in motor shell 10 tops between two

gears

2,8, the modulus of the

gear

2,8 in the present embodiment is 7mm, and the number of teeth is 11, and tooth depth is 80mm.

The utility model is work like this:

High-pressure blast is after air inlet 1 enters motor shell 10, according to descending along the inner surface of motor shell 10 after 2, the 8 rotation works done of the driven gear of the direction of arrow shown in the figure, the low-pressure air of volumetric expansion after the work done is because the effect of dividing plate 3 is passed through diffusing wind web plate 5, silencing plate 6 respectively after air outlet 9 discharges through the wind chamber 4 of motor shell 10 bottom and arranged on left and right sides.
