Description
Technical Field
The utility model belongs to the technical field of the bearing, in particular to elastic sealing end cover for slide bearing.
Background
By arranging the sealing end covers at the two ends of the sliding bearing, the leakage of internal lubricating oil and the entry of external impurities can be prevented; the sliding bearings are commonly sealed by a labyrinth, a felt, a packing and the like, the felt and the packing have poor sealing effects, the labyrinth sealing effect is relatively good, and the oil leakage phenomenon still exists; the requirement of the motor on sealing is high, and a sealing end cover which is simple, effective and convenient to install is needed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an elastic sealing end cover for slide bearing to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides an elastic sealing end cover for slide bearing, includes the end cover body, this internal installation cavity that is equipped with of end cover, elastic sealing part and floating seal part are installed from inside to outside in proper order to the installation cavity.
The end cover body comprises an extension ring plate and a hollow cylinder arranged on one side of the extension ring plate, the installation cavity is arranged on the inner wall of the hollow cylinder, and the installation cavity is annular.
The elastic sealing part is O-shaped, the cross section of the elastic sealing part is circular, and the diameter of the circle is smaller than the width of the installation cavity.
The floating sealing part is O-shaped, and the cross section of the floating sealing part is matched with the installation cavity.
An oil groove is formed in one side, close to the circle center, of the floating sealing component, and an arc-shaped groove matched with the first elastic component is formed in one side, far away from the circle center, of the floating sealing component.
The end cover body is provided with through screw holes at two sides of the mounting cavity, the floating sealing part is provided with positioning holes, and the diameter of each positioning hole is larger than that of each screw hole.
The inner wall of the hollow cylinder is provided with an oil return groove, an oil return hole is connected with the oil return groove, and the end part of the oil return hole extends to the side face of the end cover body.
The utility model discloses beneficial technological effect for prior art is:
a certain gap is formed between the floating sealing part and the end cover body in the axial direction, and the elastic sealing part is tightly attached to the end cover body in the circumferential direction to allow the shaft to jump up, down, left and right within a certain range. Because elastic sealing part has elasticity, when the axle vibrates, the sealing part inner circle atress that floats, elastic sealing part warp thereupon, and floating sealing part removes along with elastic sealing part compression direction to the complex clearance between compensation and the axle has good sealed effect, in addition, the utility model discloses still have simple structure, the effect is showing, advantages such as simple to operate.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
The utility model provides an elastic sealing end cover for slide bearing, includes end cover body 1, be equipped with the installation cavity in the end cover body 1, install elastic sealing part 4 and floating seal part 3 from inside to outside in proper order in the installation cavity.
The end cover body 1 comprises an extension annular plate and a hollow cylinder arranged on one side of the extension annular plate, the installation cavity is arranged on the inner wall of the hollow cylinder, and the installation cavity is annular.
The elastic sealing part is O-shaped, the cross section of the elastic sealing part 4 is circular, and the diameter of the circle is smaller than the width of the installation cavity.
The floating sealing component 3 is O-shaped, and the cross section of the floating sealing component 3 is matched with the installation cavity.
An oil groove 7 is formed in one side, close to the circle center, of the floating sealing component 3, and an arc-shaped groove 8 matched with the first elastic component is formed in one side, far away from the circle center, of the floating sealing component 3.
The end cover body 1 is provided with through screw holes 9 at two sides of the mounting cavity, the floating sealing part 3 is provided with positioning holes 10, and the diameter of each positioning hole 10 is larger than that of each screw hole 9.
The utility model discloses be provided with the elastic sealing part at the excircle of the sealing part that floats 3, the elastic sealing part is in end cover body 1 mounting groove, and the first half of the sealing part that floats 3 is fixed a position the first half at end cover body 1 through allen key 2, and the sealing part that will float 3 is fixed a position at certain floating range.
An oil return groove 6 is formed in the inner wall of the hollow cylinder, an oil return hole 5 is formed in the hollow cylinder and connected with the oil return groove 6, and the end portion of the oil return hole 5 extends to the side face of the end cover body 1.
The floating sealing part 3 and the end cover body 1 have a certain gap in the axial direction, and the elastic sealing part 4 is tightly attached to the end cover body 1 in the circumferential direction, so that the shaft is allowed to jump up, down, left and right within a certain range. Because elastic sealing part 4 has elasticity, when the axle vibration, the 3 inner circles atress of floating sealing part, elastic sealing part 4 warp thereupon, and floating sealing part 3 removes along with the 4 compression directions of elastic sealing part to the complex clearance between compensation and the axle, and obtain good sealed effect, in addition, the utility model discloses still have simple structure, simple to operate's characteristics.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
