Abstract
The utility model discloses a dustproof and waterproof structure of a cutting machine. The cutting machine comprises a power device, a main shaft connected to the power device, a blade pressing plate sleeved at an output shaft of the main shaft, a bearing sleeved on the main shaft and a bearing seat for accommodating the bearing. The dustproof and waterproof structure comprises a spacing sleeve and a sealing ring, wherein the spacing sleeve is sleeved on the main shaft between the bearing and the blade pressing plate; and the sealing ring is sleeved on the spacing sleeve, so that water and dust are prevented from entering the bearing as far as possible. Therefore, the dustproof and waterproof function is better.
Description
Technical field
The utility model relates to a kind of dustproof and waterproof structure, specifically, relates to a kind of dustproof and waterproof structure of cutting machine.
Background technique
The main shaft of cutting machine can produce a large amount of dusts and moisture when rotating cutting, cause the corrosion to the main shaft in the bearing support and bearing, has affected the working life of cutting machine main shaft and bearing, need badly a kind of simple in structure, the dustproof and waterproof structure of good sealing effect.
The model utility content
The purpose of this utility model just provides a kind of simple in structure, the dustproof and waterproof structure of the cutting machine that dustproof and waterproof is effective.
For addressing the above problem, the utility model provides a kind of dustproof and waterproof structure of cutting machine, described cutting machine comprises power plant, be connected in main shaft on the described power plant, be sheathed on the blade pressuring plate of described main shaft output terminal, the bearing support that is sheathed on the bearing on the described main shaft and accommodates described bearing, and described dustproof and waterproof structure comprises spacer sleeve and seal ring; Described spacer sleeve is sheathed on the main shaft between described bearing and the described blade pressuring plate; Described seal ring is sheathed on the described spacer sleeve.
Preferably, described spacer sleeve and described seal ring transition fit.
Preferably, it is inner that described spacer sleeve and described seal ring all are contained in described bearing support, and described seal ring contact connects the inwall of described bearing support.
Preferably, the counterface of described blade pressuring plate and described bearing support is processed with the labyrinth structure of mutual coupling, the counterface Spielpassung of described blade pressuring plate and described bearing support.
Preferably, described seal ring is X-shaped sealing ring or outside framework oil seal.
Preferably, the fitting surface of described blade pressuring plate and described main shaft output terminal is processed with the plane of mutual coupling.
Adopt the beneficial effect of this technological scheme to be, on the one hand, spacer sleeve cooperates with seal ring and forms a stairstepping, can greatly reduce water and dust enters bearing support inside; On the other hand, be processed with the labyrinth seal structure of mutual coupling on the counterface of bearing support and blade pressuring plate, prevent that effectively moisture and dust from entering the main shaft surface.
Description of drawings
Fig. 1 is the structural representation of the dustproof and waterproof structure of a kind of cutting machine of the utility model.
Wherein, 1. main shaft 2. blade pressuring plates 3. bearings 4. bearing supports 51. spacer sleeve 52.X RunddichtringOs.
Embodiment
Describe specific embodiment of the utility model in detail below in conjunction with accompanying drawing.
Embodiment 1
Referring to Fig. 1, shown in legend wherein, a kind of dustproof and waterproof structure of cutting machine, above-mentioned cutting machine comprises a power plant (not shown), be connected in a main shaft 1 on the power plant, be sheathed on a blade pressuring plate 2 of main shaft 1 output terminal, a bearing support 4 that is sheathed on the bearing 3 on the main shaft 1 and accommodates bearing 3, and above-mentioned dustproof and waterproof structure comprises a spacer sleeve 51 and an X-shaped sealing ring 52; Spacer sleeve 51 is sheathed on the main shaft 1 between bearing 3 and the described blade pressuring plate 2; Seal ring 52 is sheathed on the spacer sleeve 51.
Spacer sleeve 51 and X-shaped sealing ring 52 transition fit.
The dust that cutting machine produces when cutting and moisture are spaced apart cover 51 and X-shaped sealing ring 52 isolation, alleviate the corrosion to bearing 3 and bearing support 4.
Embodiment 2
Referring to Fig. 1, shown in legend wherein, all the other are identical with described embodiment 1, and difference is that spacer sleeve 51 all is contained in the inwall that bearing support 4 inner X-shaped sealing rings 52 contact coupling shaft bearing 4 with X-shaped sealing ring 52.
The dust that cutting machine produces when cutting and moisture are spaced apart cover 51 and X-shaped sealing ring 52 isolation, reduce the inside that moisture and dust enter bearing support 4.
Embodiment 3
Referring to Fig. 1, shown in legend wherein, the counterface of blade pressuring plate 2 and bearing support 4 is processed with the labyrinth structure of mutual coupling, and the counterface Spielpassung of blade pressuring plate 2 and bearing support 4 can prevent effectively that dust and moisture from entering into the surface of main shaft.
Embodiment 4
All the other are identical with described embodiment 3, and difference is that X-shaped sealing ring is outside framework oil seal.
Embodiment 5
All the other are identical with described embodiment 3, and difference is, blade pressuring plate 2 and the fitting surface of main shaft 1 output terminal are processed with the plane of mutual coupling.
Adopt the beneficial effect of this technological scheme to be, on the one hand, spacer sleeve cooperates with seal ring and forms a stairstepping, can greatly reduce water and dust enters bearing support inside; On the other hand, be processed with the labyrinth seal structure of mutual coupling on the counterface of bearing support and blade pressuring plate, prevent that effectively moisture and dust from entering the main shaft surface.
The above only is preferred implementation of the present utility model, should be pointed out that under the prerequisite that does not break away from the utility model creation design, and can also make some distortion and improvement, these all belong to protection domain of the present utility model.
