Abstract
The utility model discloses a drive reduction mechanism of a down-hole drill. An eccentric bearing 5 is arranged in a gearbox, a pair of cycloid gear wheels 6 is arranged on the eccentric bearing 5 and is meshed with inner gear wheels 8 of the gearbox, thereby realizing the required reduction coefficient, further, pins 7 are uniformly distributed at the large end of an output shaft 13 and are disposed in corresponding holes of the cycloid gear wheels 6, and the small end of the output shaft 13 is connected with a pneumatic shaft of the down-hole drill through an bearing of the output shaft. After improving, advantages of a cycloidal pin and a gear reducer can dually function, thereby achieving the purpose of increasing torque force and reducing maintenance, and safety and reliability.
Description
Technical field
The utility model relates to a kind of transmission device, the used down-the-hole drill machine transmission speed reducer structure of especially a kind of open-air stone ore exploitation.
Background technology
Down-the-hole drill is widely used in large, medium and small type mine and builds the road, and runs hole rock drilling operation than major diameter in the engineerings such as national defence, water conservancy.Owing to the existing drilling depths of factor affecting such as being subjected to the mountain height increases gradually, torsional forces that needs and power also strengthen gradually.At present, the reductor of selling on the market generally adopts gear and two kinds of reducing gears of cycloid pin, facts have proved that said gear reductor torsional forces is more easy to maintenance, but volume and noise is bigger, though cycloid pin reductor has remedied the shortcoming of gear reduction unit, install and maintenance religion complexity.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and provides a kind of rational in infrastructure, safe and reliable, down-the-hole drill transmission speed reducer structure easy to maintenance.
The technical solution of the utility model realizes in the following manner:
Aforesaid down-the-hole drill transmission speed reducer structure, be that capacity eccentric bearing is set in gearbox, a pair of cycloid tooth wheel disc is set on the capacity eccentric bearing, cycloid tooth wheel disc and the interlock of gearbox ring gear, reach required moderating ratio, the big end of output shaft is evenly equipped with pivot pin, and pivot pin is arranged in the corresponding hole of cycloid tooth wheel disc, and the output shaft small end is connected with down-the-hole drill gas axle by bearing.
Drive line of the present utility model in sum is: motor shaft capacity eccentric bearing-cycloid tooth wheel disc-ring gear-output shaft.
The utility model makes the dual performance of advantage of cycloid pin and gear reduction unit by improvement, has reached the increase torsional forces, reduces maintenance, safe and reliable purpose.
