Abstract

A main shaft drive system for a low-speed large torque lathe includes an electric motor and a drive gear case. The motor is a DC motor or an AC conversion motor. The gear case is provided with a gear a, a gear b, a duplicate shifting slide gear, a gear c, a gear d, a shifting slide gear, an internal gear clutch, a gear e, a gear f, a gear g, a helical gear h, a helical gear i, a first shaft, a second shaft, a third shaft, a fourth shaft, a fifth shaft and a sixth shaft. The invention has the advantages of excellent speed regulation performance and simple structure; and the main shaft drive system can finish large torque output when at a low speed of 1 to 125rn/min. The output torque of the main shaft is large, the cutting depth is increased, the cutting quantity is enlarged and the latch processing is improved. When conducting a rough machining, the advantage can be more predominant.

Background technology

At present, the lathe spindle rotating speed of tactical diameter Φ 1250mm is generally 3.15～400 rev/mins, it is to drive with ordinary three-phase synchronous, this electric machine speed regulation is bad, motor speed makes main shaft obtain different rotating speeds by several to slip teeth wheel speed change, the mechanical speed change complex structure, and slewing range is limited, the main shaft output torque is less, can't realize slow cutting; And spindle speed is to realize by the secondary speed change of main spindle box shifting slide gear, makes the main spindle box structure very complicated.

Summary of the invention

The technical problem to be solved in the present invention provides a kind of main axis transmission system of lower speed big torque lathe.This system can make lathe finish various turneries, and it can the various parts of turning and profiled surface such as cylindrical, endoporus, end face, also can satisfy boring, bore hole, etc. technological requirement; And high pulling torque output when this main axis transmission system can be finished 1～125 rev/min of low speed, the main shaft output torque is big, and the depth of cut strengthens, and increases cutting data, improves machine tooling efficient, and these characteristics are more outstanding during roughing.

For solving the problems of the technologies described above, the present invention adopts following technical scheme: it comprises motor, uni-drive gear box; Described motor is direct current generator or alternating-current variable frequency motor; Be provided with gear a, gear b, double crosslinking sliding gear, gear c, gear d, shifting slide gear, internal gear clutch, gear e, gear f, gear g, helical gear h, helical gear i, I axle, II axle, III axle, IV axle, V axle and VI axle in the described uni-drive gear box; Described motor connects by a shaft coupling with the I axle, and gear a is housed on the I axle, and described gear b is installed on the II axle, and described gear a and gear b are meshing; Also set firmly double crosslinking sliding gear on the described II axle, set firmly gear c and gear d on the described III axle, the double crosslinking sliding gear on the described II axle is by c and the gear d engagement that cogs of slippage on the II axle and III axle; Also set firmly shifting slide gear on the described III axle, and establish internal gear clutch at the low order end of III axle by bearing, this internal gear clutch is fixedly connected with axle V left end; Set firmly gear e on the described IV axle, the right-hand member of axle IV is equipped with gear f, and the shifting slide gear that sets firmly on described gear e and the III axle can be meshing, described gear f and the gear g engagement that is contained on the V axle; The right-hand member of described V axle is equipped with helical gear h, with the helical gear i engagement that is contained on the VI axle.

The present invention has good speed governing, high pulling torque output when simple in structure and this main axis transmission system can be finished 1～125 rev/min of low speed, the main shaft output torque is big, and the depth of cut strengthens, and increases cutting data, improve machine tooling efficient, these characteristics are more outstanding during roughing.
