Abstract
The utility model discloses a transmission system for a spindle box of a boring and milling machine, which comprises a boring shaft, a motor and a spindle box body. The motor comprises a motor rotor, a motor stator and a motor shell, wherein the motor rotor is fixedly mounted on a hollow shaft, and the motor stator is fixedly mounted on the spindle box body. Besides, the hollow shaft is supported in the spindle box body through bearings, and the boring shaft is mounted in the hollow shaft. The transmission system is simple in structure and higher in precision, transmission efficiency and rotation speed.
Description
Technical field
The utility model belongs to the Metal Cutting Machine Tool field, especially relates to a kind of milling-boring machine main spindle box transmission system.
Background technology
Along with the high speed development of China's machinery manufacturing industry, increasing to the demand of various milling-boring machines, existing milling-boring machine main spindle box transmission system needs mechanical reduction and mechanical speed change, complex structure, and precision, efficient and rotating speed are all on the low side.
Summary of the invention
The purpose of the utility model is: a kind of simple for structure, transmission efficiency and the high milling-boring machine main spindle box transmission system of rotating speed are provided.
The technical scheme of the utility model is: milling-boring machine main spindle box transmission system comprises boring axle, motor, main shaft casing; Motor comprises rotor, motor stator and motor housing; Rotor is fixedly mounted on the hollow shaft; Motor stator is fixedly mounted on the main shaft casing, and in the main shaft casing, the boring axle is installed in the hollow shaft hollow shaft through bearings.
The end of said hollow shaft can the installed with milling cutter dish.
Said rotor connects the drive encoder through synchronous belt transmission device.
The beneficial effect of the utility model is: since milling-boring machine main spindle box transmission adopted rotor directly be fixedly mounted on the hollow shaft; Motor stator directly is fixed on the main shaft casing; Hollow shaft is supported between the front and back bearings in the main shaft casing, and the boring axle is installed in the hollow shaft, makes milling-boring machine main spindle box transmission system form the direct drive sleeve of motor, boring axle; Thereby making the structure of milling-boring machine main spindle box transmission system more succinct, precision, transmission efficiency and rotating speed are higher.
