Abstract
The utility model discloses a high-strength slewing bearing isolation block, which comprises an isolation block body, wherein the isolation block body is of a cylindrical structure, two end surfaces of a cylinder of the isolation block body are provided with inwards concave spherical grooves, and the outer wall of the cylinder of the isolation block body is provided with a metal shell.
Description
Technical Field
The utility model belongs to the technical field of design of slewing bearing isolation blocks, and particularly relates to a high-strength slewing bearing isolation block.
Background
The slewing bearing is a novel industrial part developed in the world in recent years, can simultaneously bear comprehensive loads such as axial load, radial load, overturning moment and the like, and is a large bearing with a special structure integrating multiple functions such as supporting, rotating, transmission, fixing and the like.
The traditional material of the isolating block for the slewing bearing is cast aluminum alloy or aluminum bronze and the like, but the manufacturing efficiency is low and the cost is high, and the production of the high-strength and light-weight engineering plastic isolating block by adopting an injection molding process is the current technical development direction. However, plastic parts have disadvantages of low structural strength and uneven strength distribution, relative to steel parts. When the rolling element (steel ball) is stressed too much, the engineering plastic spacer is easily damaged, and then the normal operation of the slewing bearing is affected, so a high-strength slewing bearing spacer is needed to solve the problems.
Disclosure of Invention
In order to solve the technical problems, the utility model provides a high-strength slewing bearing isolation block which is simple in structure and reasonable in design, a metal shell is arranged outside the isolation block made of the existing engineering plastic material so as to improve the strength of the isolation block, and the isolation block has the characteristics of wear resistance and high temperature resistance, so that the condition that the isolation block is damaged due to overlarge stress of a steel ball is effectively avoided, the service life of the isolation block is prolonged, and the normal operation of the slewing bearing is ensured.
The technical scheme adopted by the utility model is as follows: the utility model provides a high strength slewing bearing spacing block, includes the spacing block body, and spacing block body appearance is the cylinder structure, is equipped with inside sunken spherical recess in the both ends face position of spacing block body cylinder, and metal casing is installed to the cylinder outer wall position of spacing block body.
The isolation block body is made of nylon.
The cylindrical outer wall position of spacing block body is equipped with an inside sunken annular, and metal casing's inner wall department is equipped with bellied spacing ring, and the spacing ring corresponds to be installed in the annular.
The metal shell is made of aluminum alloy or copper.
In operation, slewing bearing's steel ball is located the spherical recess at spacing block body both ends, adopt the spacing block to keep apart two adjacent steel balls promptly, wherein, spacing block both ends spherical recess and the contact of steel ball outer wall, and the cylinder external diameter of spacing block is in unsettled state in slewing bearing inside, avoid contacting with slewing bearing track face, along with slewing bearing's operation, the steel ball rotates inside slewing bearing, when the steel ball atress is too big, can exert certain effort for the spacing block, because metal casing installs in the outside position of spacing block body, can increase the holistic structural stability of spacing block, avoid the spacing block to produce the damaged condition after the effort that receives the steel ball, the life of effectual improvement spacing block, guarantee slewing bearing normal operating.
The two end faces of the cylinder of the isolation block body are provided with inward concave spherical grooves, and the outer wall of the cylinder of the isolation block body is provided with a metal shell; the purpose of this is: the diameter of the spherical groove is equal to that of the steel ball, so that the steel ball is limited and isolated; the metal casing that sets up is used for increasing the holistic structural strength of clutch blocks, because the clutch blocks body is the nylon material, sets up metal casing in clutch blocks body outside position, can guarantee the intensity of whole clutch blocks under the circumstances of reduce cost, improves its life, avoids frequently appearing damaged problem when slewing bearing operates.
The utility model has the beneficial effects that:
the utility model has simple structure and reasonable design, the metal shell is arranged outside the isolation block made of the existing engineering plastic material to improve the strength of the isolation block, and the isolation block has the characteristics of wear resistance and high temperature resistance, thereby effectively avoiding the damage of the isolation block caused by overlarge stress of the steel ball, prolonging the service life of the isolation block and ensuring the normal work of the slewing bearing.
Drawings
FIG. 1 is a perspective view of the present invention;
fig. 2 is a cross-sectional view of the present invention.
The labels in the figure are: 1. a spacer block body; 2. a metal housing; 201. a limiting ring; 3. a spherical recess.
Detailed Description
The following detailed description of embodiments of the utility model is provided in connection with the accompanying drawings.
As shown in the figure, a high strength slewing bearing spacing block, including spacing block body 1, spacing block body 1 appearance is the cylinder structure, is equipped with inside sunken spherical recess 3 in the both ends face position of spacing block body 1 cylinder, and metal casing 2 is installed to the cylinder outer wall position of spacing block body 1.
The isolation block body 1 is made of nylon materials, is made of nylon 66 and is made of thermoplastic resin, and has the characteristics of high mechanical strength and hardness and high rigidity.
The cylindrical outer wall position of spacing block body 1 is equipped with one inside sunken annular, and metal casing 2's inner wall department is equipped with bellied spacing ring 201, and spacing ring 201 corresponds installs in the annular, so sets up, can improve metal casing 2 and spacing block body 1's connection fastening nature, prevents that metal casing 2 from producing the problem of droing.
The metal shell 2 is made of aluminum alloy or copper, and has the effect of improving the overall strength of the isolation block body 1.
In operation, slewing bearing's steel ball is located the spherical recess 3 at spacing block body 1 both ends, adopt the spacing block to keep apart two adjacent steel balls promptly, wherein, spacing block both ends spherical recess 3 and the contact of steel ball outer wall, and the cylinder external diameter of spacing block is in unsettled state in slewing bearing inside, avoid contacting with slewing bearing track face, along with slewing bearing's operation, the steel ball rotates inside slewing bearing, when the steel ball atress is too big, can apply certain effort for the spacing block, because metal casing 2 installs in the outside position of spacing block body 1, can increase the holistic structural stability of spacing block, avoid the spacing block to produce the damaged condition after the effort that receives the steel ball, the life of effectual improvement spacing block, guarantee slewing bearing normal operating.
