Abstract
The invention relates to mechanical manufacturing industries, in particular to a spindle waterproof mechanism which particularly comprises a spindle, a flange cover, a flange disc, a joint, an air pipe, an outer spacing sleeve, an inner spacing sleeve, a sealing ring, an adjusting pad and a box. The adjusting pad presses a bearing outer ring, the inner spacing sleeve presses a bearing inner ring, the flange disc presses the outer spacing sleeve and is connected with the box, the air pipe is connected with the joint to be mounted on an air hole of the flange disc, the sealing ring is mounted in an annular groove of the flange disc, a shaft neck of the spindle presses the inner spacing sleeve, and the flange cover is connected with the flange disc. Compared with the prior art, the spindle waterproof mechanism has the advantages of reliable structure, low temperature increase and complete water proofing, water can be effectively prevented from entering the spindle, and the service life of equipment is prolonged.
Description
Technical field
What the present invention relates to is machine industry, is specially a kind of main-shaft waterproof mechanism.
Background technique
Adopt at present two kinds of waterproof constructions of the general employing of power unit of machine tool main shaft of wet type processing mode, a kind of is to fill dewatering means on main shaft and flange plate, this kind structurally waterproof is not thorough, causes main shaft bearing to get rusty, and a kind of is the dress waterproof grommet, this kind mode can have waterproofing effect preferably, but when unit head has higher rotation speed, can cause seal ring to generate heat and wear and tear, these two kinds of structures are all unreliable, very easily cause main shaft to damage, reduce the working life of equipment.
Summary of the invention
The purpose of this invention is to provide a kind of main-shaft waterproof mechanism, its waterproof is thorough, and temperature rise is low, and reliable in structure is not easy to wear.
Technical solution of the present invention is: a kind of main-shaft waterproof mechanism, specifically comprise: main shaft, blind flange, flange plate, joint, tracheae, outer separator, inner spacing collar, seal ring, spacer, casing, spacer is pushed down bearing outer ring, inner spacing collar is pushed down bearing inner race, flange plate is pushed down outer separator and is connected with casing, and tracheae and joint are mounted on the pore of flange plate, and seal ring is arranged in the circular trough of flange plate, the axle journal of main shaft is pushed down inner spacing collar, and blind flange is connected with flange plate.
Advantage of the present invention is as follows: compared with prior art, this mechanism has reliable in structure, and temperature rise is low, and waterproof is advantage thoroughly, effectively prevents the main shaft water inlet, has extended the working life of equipment.
Description of drawings
The present invention is further described with implementing principle below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present invention.
Embodiment
as shown in Figure 1, a kind of main-shaft waterproof mechanism, specifically comprise: main shaft (1), blind flange (2), flange plate (3), joint (4), tracheae (5), outer separator (6), inner spacing collar (7), seal ring (8), spacer (9), casing (10), spacer (9) is pushed down bearing outer ring, inner spacing collar (7) is pushed down bearing inner race, flange plate (3) is pushed down outer separator (6) and is connected with casing (10), tracheae (5) is mounted on the pore of flange plate (3) with joint (4), seal ring (8) is arranged in the circular trough of flange plate (3), the axle journal of main shaft (1) is pushed down inner spacing collar (7), blind flange (2) is connected with flange plate (3), the connection place has rhone.
The specific works principle: water is from main shaft (1) when end face enters, have effluent trough in blind flange (2) end face lower end, part water is flowed out by rhone, there is ring-like tank at position in main shaft (1) and flange plate (3) combination, under the High Rotation Speed of main shaft, water can throw away through the rhone of blind flange (2) with flange plate (3) connection place, flange plate (3), main shaft (1), inner spacing collar (7), outer separator (6) form a ring-like chamber, tracheae (5) is blown to ring-like Seal cage, formation hermetic seal chamber stops water to enter the inside of main shaft (1).
Claims (1)
1. main-shaft waterproof mechanism, it comprises: main shaft (1), blind flange (2), flange plate (3), joint (4), tracheae (5), outer separator (6), inner spacing collar (7), seal ring (8), spacer (9), casing (10), it is characterized in that, spacer (9) is pushed down bearing outer ring, inner spacing collar (7) is pushed down bearing inner race, flange plate (3) is pushed down outer separator (6) and is connected with casing (10), tracheae (5) is mounted on the pore of flange plate (3) with joint (4), seal ring (8) is arranged in the circular trough of flange plate (3), the axle journal of main shaft (1) is pushed down inner spacing collar (7), blind flange (2) is connected with flange plate (3), the connection place has rhone.
