Abstract
The utility model discloses a main-shaft waterproof mechanism, specifically comprising a main shaft, 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 body, wherein a bearing outer ring is pressed by the adjusting pad; a bearing inner ring is pressed by the inner spacing sleeve; the outer spacing sleeve is pressed by the flange disc to be connected with the box body; the air pipe is connected with the joint and then is arranged on an air hole of the flange disc; the sealing ring is arranged in a ring-shaped groove of the flange disc; the inner spacing sleeve is pressed by a shaft neck of the main shaft; and the flange cover is connected with the flange disc. Compared with the prior art, the main-shaft waterproof mechanism has the advantages of reliable structure, low temperature rise and thorough waterproof property, so that the water is effectively prevented from entering the main shaft and the service life of the 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 two kinds of waterproof constructions of the general employing of lathe dynamic head main spindle of wet type processing mode at present, a kind of is on main shaft and flange plate, to adorn dewatering means, and this kind structurally waterproof is not thorough; Cause main shaft bearing to get rusty, a kind of is the dress waterproof grommet, and this kind mode can have waterproofing effect preferably; But when unit head has higher rotation speed, can cause seal ring heating 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 comprises: main shaft, blind flange, flange plate, joint, tracheae, outer separator, inner spacing collar, seal ring, spacer, casing, and 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 linked to each other with casing, and tracheae and joint are mounted on the pore of flange plate, and seal ring is installed in the circular trough of flange plate; The axle journal of main shaft is pushed down inner spacing collar, and blind flange links to each other with flange plate.
Advantage of the present invention is following: compared with prior art, this mechanism has reliable in structure, and temperature rise is low, and waterproof is advantage completely, effectively prevents the main shaft water inlet, has prolonged the working life of equipment.
Description of drawings
Below in conjunction with accompanying drawing and enforcement principle the present invention is further specified.
Fig. 1 is a 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, and inner spacing collar (7) is pushed down bearing inner race; Flange plate (3) is pushed down outer separator (6) and is linked to each other with casing (10); Tracheae (5) is mounted on the pore of flange plate (3) with joint (4), and seal ring (8) is installed in the circular trough of flange plate (3), and the axle journal of main shaft (1) is pushed down inner spacing collar (7); Blind flange (2) links to each other with flange plate (3), and the connection place has rhone.
Concrete working principle: when water gets into from main shaft (1) end face; Have effluent trough in blind flange (2) end face lower end, a part of water is flowed out by rhone, at the position of main shaft (1) and flange plate (3) combination ring-like tank is arranged; Under the high speed rotating of main shaft; Water can throw away through the rhone of blind flange (2) with flange plate (3) connection place, and flange plate (3), main shaft (1), inner spacing collar (7), outer separator (6) are formed a ring-like chamber, and tracheae (5) is blown to ring-like Seal cage; Form the hermetic seal chamber, stop water to get into the inside of main shaft (1).
Claims (1)
