Abstract

The utility model relates to a spindle structure. The spindle structure is characterized in that a first flange plate is arranged on a workbench base, a self-aligning roller bearing, a first spacer bush, a second spacer bush, a first angular contact ball bearing, a third spacer bush, a fourth spacer bush and a second angular contact ball bearing are mounted on the first flange plate in sequence and then are pressed by a second flange plate, the second flange plate is fixed to the first flange plate, and then a spindle is put in; a fifth spacer bush is put in from the upper portion of the spindle, then a gear is put in, and the gear and a spindle nose of the spindle are pressed by a press cover; a belt wheel is mounted on the spindle from the lower portion of the spindle, and the belt wheel is pressed by a spacer bush and a locking nut. The spindle structure is simple, ingenious and reasonable in structure, the reduction of the transmission levels of the spindle can be achieved, a transmission process is even, stable and low in noise, and the spindle structure is stable and reliable.

Description

A kind of main axle structure

Technical field

The utility model relates to a kind of main axle structure, is specially adapted to vertical lathe, belongs to mechanical equipment technical field.

Background technology

Vertical car is mainly used in processing that diameter is large, length is short is large-scale, heavy workpiece and be difficult for the workpiece of clamping on horizontal lathe, in the satisfied situation of tactical diameter, too heavy workpiece is difficult for clamping at sleeping carriage, due to dead weight, machining accuracy is had to impact, adopt vertical car to address the above problem.

In prior art, spindle drive is more loaded down with trivial details, therefore the structure of main shaft is optimized to design and just seems particularly necessary.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of main axle structure is provided, and this main axle structure is simple, ingenious, reasonable, and it can be realized spindle drive progression and tail off, and transmission process evenly, steadily, and noise is little, reliable and stable.

The technical scheme providing according to the utility model: a kind of main axle structure comprises table base, locking nut, spacer, belt pulley, main shaft, outside framework oil seal, the first ring flange, self-aligning roller bearing, the first spacer, the second spacer, the first angular contact ball bearing, the 3rd spacer, the 4th spacer, the second angular contact ball bearing, the second ring flange, the 5th spacer, gear and gland; Described the first ring flange is arranged on table base; Self-aligning roller bearing, the first spacer, the second spacer, the first angular contact ball bearing, the 3rd spacer, the 4th spacer, the second angular contact ball bearing are housed successively on described the first ring flange, then with the second ring flange, push down, the second ring flange is fixed on the first ring flange, then main shaft is packed into; Above main shaft, pack the 5th spacer into, and then gear is packed into, with gland, be pressed on gear and main-shaft spindle head; Described main shaft below, then belt pulley is arranged on main shaft, with spacer and locking nut, push down.

As further improvement of the utility model, in the inner ring of described the first ring flange, be provided with an outside framework oil seal, prevent leakage of oil,

Compared with prior art, advantage is the utility model: main axle structure is simple, ingenious, reasonable, and it can be realized spindle drive progression and tail off, and transmission process evenly, steadily, and noise is little, reliable and stable.

Accompanying drawing explanation

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

The specific embodiment

Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.

As shown in Figure 1, table base 1, locking nut 2, spacer 3, belt pulley 4, main shaft 5, outside framework oil seal 6, the first ring flange 7, self-aligning roller bearing 8, the first spacer 9, the second spacer 10, the first angular contact ball bearing 11, the 3rd spacer 12, the 4th spacer 13, the second angular contact ball bearing 14, the second ring flange 15, the 5th spacer 16, gear 17, gland 18 and bolt 19.

As shown in Figure 1, the utility model is a kind of main axle structure, comprises table base 1, is arranged on the ring flange 7 on table base 1, with bolt, fixes.Self-aligning roller bearing 8, the first spacer 9, the second spacer 10, the first angular contact ball bearing 11, the 3rd spacer 12, the 4th spacer 13, the second angular contact ball bearing 14 are housed successively on described the first ring flange 7, then with the second ring flange 15, push down, this second ring flange 15 is fixed on the first ring flange 7, then main shaft 5 is put into; Above main shaft 5, reinstall the 5th spacer 16, and then gear 17 is packed into, gland 18 is placed on gear 17 and main shaft 5 spindle noses, with bolt 19, tighten; Below main shaft 5, in the inner ring of ring flange 7, put an outside framework oil seal 6, prevent leakage of oil, then belt pulley 4 is arranged on main shaft 5, with spacer 3 and locking nut 2, push down.

This main axle structure of the utility model is simple, ingenious, reasonable, and it can be realized spindle drive progression and tail off, and transmission process evenly, steadily, and noise is little, reliable and stable.
