Abstract
The utility model discloses a balanced type universal joint. A traditional universal joint is large in rotation torque, large in friction force and prone to abrasion. The balanced type universal joint comprises a left shell, a ball core, a right shell and a gland, the left shell and the right shell are spliced to be an integral shell, the gland is arranged at the toroidal surface of the large-diameter position of the left shell, the gland is provided with a screw hole, a screw hole is correspondingly formed in the edge of the right shell, and the gland and the right shell are fixedly connected through a bolt. The ball core is arranged inside the integral shell and can rotate freely, and the inner diameter of the integral shell is roughly larger than the outer diameter of the ball core. A cylinder at the small-diameter position of the left shell and a cylinder at one end of the ball core are connected with the end portion of a pipeline to be connected, and abrasion between the inner wall of the integral shell and the ball core is reduced greatly. The gland of the universal joint is matched with the bolt so as to achieve the purpose of enclosing the ball core inside the shell, and the universal joint is convenient to maintain when breaking down. The universal joint is symmetrical in structure, unbalance caused by the asymmetry structure of the traditional universal joint is avoided, and the service life of the universal joint is prolonged.
Description
Technical field
The utility model relates to a kind of universal joint, particularly when two pipelines exist the angle of cut, plays the crossover sub of connection function, belongs to pipe joint technical field.
Background technique
Between known pipeline often by flange connect, clip connected, above-mentioned two kinds of Placements are for the pipeline of two deads in line, but for there being two pipelines of certain angle of cut scope between axis, often need to install universal joint.Universal joint on market is comprised of connecting rod, dwang, bulb, and connecting rod and bulb are as a whole, and dwang is provided with the housing coordinating with bulb.This universal joint is due to the existence of connecting rod brachium, and moment of rotation is larger, and corresponding bulb part is also larger with the active force of housing, and the frictional force between bulb and housing is also larger, causes universal joint easy to wear, and shorten working life.This universal joint, because structure is more complicated, is not easy to manufacture simultaneously, and dismounting is also inconvenient, is not easy to maintenance.
Model utility content
For the deficiencies in the prior art, the utility model proposes and connect a kind of wear-resistant, detachable, the long service life in two-phase traffic control road, the universal joint of symmetric design.
To achieve these goals, the utility model adopts following technological scheme: a kind of equalization type universal joint is provided, comprise left shell, ball core, right shell body, gland, left shell, right shell body piece together housing integral body, place, the large footpath of left shell toroidal surface is provided with a gland, gland is provided with screw, the corresponding screw that is provided with in right shell body edge, and gland and right shell body are bolted to connection.Ball core is arranged on housing whole interior free to rotate, and the whole internal diameter of housing is slightly larger than ball core external diameter.
The utility model left shell path place cylinder, ball core one end cylinder are connected with the end of pipeline to be connected respectively.Because left shell, right shell body piece together housing integral body, can regularly take housing integral body apart, add oiling agent, greatly reduced the wearing and tearing between inner walls and ball core.This universal joint gland coordinates with bolt, plays the object that ball core is enclosed in to spherical shell, therefore, and convenient for maintaining when universal joint breaks down.This gimbal structure is symmetrical, avoids the asymmetric imbalance causing of traditional gimbal structure, has extended working life.
As the utility model, further improve, ball core rotation angle is-15 °～15 °.
Accompanying drawing explanation
Fig. 1 is the half section structural drawing of the utility model normal state;
Fig. 2 is left TV structure schematic diagram of the present utility model;
Fig. 3 is the half section structural drawing of the utility model working state.
In figure: 1, left shell, 2, gland, 3, right shell body, 4, ball core.
Embodiment
15 ° of the ball core rotation angles of take are below example, with specific embodiment, the utility model are illustrated by reference to the accompanying drawings:
As shown in Figures 1 to 3, the present embodiment comprises left shell 1, ball core 4, right shell body 3, gland 2, left shell 1, right shell body 3 piece together housing integral body, place, the large footpath of left shell 1 toroidal surface is provided with a gland 2, gland 2 is provided with screw, the corresponding screw that is provided with in right shell body 3 edges, gland 2 is bolted to connection with right shell body 3.Ball core 4 is arranged on housing whole interior free to rotate, and the whole internal diameter of housing is slightly larger than ball core 4 external diameters.
During work, left shell 1 path place cylinder, ball core 4 one end cylinders are connected with the end of pipeline to be connected respectively.As shown in Figure 3, ball core 4 rotation angles are 15 ° to the maximum.Because left shell 1, right shell body 3 piece together housing integral body, can regularly take housing integral body apart, add oiling agent, greatly reduced the wearing and tearing of 4, inner walls and ball core.This universal joint gland 2 coordinates with bolt, plays the object that ball core 4 is enclosed in to spherical shell, therefore, and convenient for maintaining when universal joint breaks down.This gimbal structure is symmetrical, avoids the asymmetric imbalance causing of traditional gimbal structure, has extended working life.
The above embodiment is preferred embodiment of the present utility model, not with this, limits practical range of the present utility model, therefore the equivalence that all structures according to the utility model and material are done changes, all should be covered by protection domain of the present utility model.
Claims (2)
1. an equalization type universal joint, is characterized in that comprising left shell, ball core, right shell body, gland, and described left shell, right shell body piece together housing integral body; Place, the large footpath of described left shell toroidal surface is provided with a gland, and described gland is provided with screw, the corresponding screw that is provided with in described right shell body edge, and described gland and right shell body are bolted to connection; Described ball core is arranged on housing whole interior free to rotate, and the whole internal diameter of housing is slightly larger than described ball core external diameter.
