Abstract
The invention discloses a kind of equalization type universal joint.Tradition universal joint moment of rotation is comparatively large, and frictional force is also comparatively large, easy to wear.The present invention includes left shell, ball core, right shell body, gland, left shell, right shell body piece together housing entirety, and left shell large footpath place toroidal surface is provided with a gland, and gland is provided with screw, right shell body edge is corresponding is provided with screw, and gland and right shell body are bolted to connection.Ball core is arranged on housing whole interior and free to rotate, and the overall internal diameter of housing is slightly larger than ball core external diameter.Left shell path place of the present invention cylinder, ball core one end cylinder are connected with the end of pipeline to be connected respectively, greatly reduce the wearing and tearing between inner walls and ball core.This universal joint gland coordinates with bolt, plays object ball core being enclosed in spherical shell, therefore, and the convenient for maintaining when universal joint breaks down.This gimbal structure is symmetrical, avoids the asymmetric imbalance caused of traditional gimbal structure, extends working life.
Description
Technical field
The present invention relates to a kind of universal joint, particularly play the crossover sub of connection function when two pipelines exist the angle of cut, belong to pipe joint technical field.
Background technique
Usually through Flange joint, clip connected between known pipeline, above-mentioned two kinds of Placements for the pipeline of two deads in line, but for there are two pipelines of certain intersection range between axis, often need to install universal joint.Universal joint on market is made up of connecting rod, dwang, bulb, connecting rod and bulb as a whole, dwang is provided with the housing coordinated with bulb.This universal joint is due to the existence of connecting rod brachium, and moment of rotation is comparatively large, and the active force of corresponding bulb part and housing is also comparatively large, and the frictional force between bulb and housing is also comparatively large, and cause universal joint easy to wear, working life shortens.Simultaneously this universal joint due to structure more complicated, be not easy to manufacture, dismounting is also inconvenient, be not easy to maintenance.
Summary of the invention
For the deficiencies in the prior art, the present invention proposes the universal joint of a kind of wear-resistant, detachable, long service life, the symmetric design in connection two intersecting pipes road.
To achieve these goals, the present invention adopts following technological scheme: provide a kind of equalization type universal joint, comprise left shell, ball core, right shell body, gland, left shell, right shell body piece together housing entirety, left shell large footpath place toroidal surface is provided with a gland, gland is provided with screw, and right shell body edge is corresponding is provided with screw, and gland and right shell body are bolted to connection.Ball core is arranged on housing whole interior and free to rotate, and the overall internal diameter of housing is slightly larger than ball core external diameter.
Left shell path place of the present invention 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 entirety, can regularly take housing entirety apart, add oiling agent, greatly reduce the wearing and tearing between inner walls and ball core.This universal joint gland coordinates with bolt, plays object ball core being enclosed in spherical shell, therefore, and the convenient for maintaining when universal joint breaks down.This gimbal structure is symmetrical, avoids the asymmetric imbalance caused of traditional gimbal structure, extends working life.
Further improve as the present invention, ball core rotation angle is-15 ° ~ 15 °.
Accompanying drawing explanation
Fig. 1 is the half section structural drawing of normal state of the present invention;
Fig. 2 is left TV structure schematic diagram of the present invention;
Fig. 3 is the half section structural drawing of working state of the present invention.
In figure: 1, left shell, 2, gland, 3, right shell body, 4, ball core.
Embodiment
Below for ball core rotation angle 15 °, with specific embodiment, the present invention is 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 entirety, left shell 1 large footpath place toroidal surface is provided with a gland 2, gland 2 is provided with screw, right shell body 3 edge is corresponding is provided with screw, and gland 2 and right shell body 3 are bolted to connection.Ball core 4 is arranged on housing whole interior and free to rotate, and the overall internal diameter of housing is slightly larger than ball core 4 external diameter.
During work, left shell 1 path place cylinder, ball core 4 one end cylinder are connected with the end of pipeline to be connected respectively.As shown in Figure 3, ball core 4 rotation angle is 15 ° to the maximum.Because left shell 1, right shell body 3 piece together housing entirety, can regularly take housing entirety apart, add oiling agent, greatly reduce the wearing and tearing between inner walls and ball core 4.This universal joint gland 2 coordinates with bolt, plays object ball core 4 being enclosed in spherical shell, therefore, and the convenient for maintaining when universal joint breaks down.This gimbal structure is symmetrical, avoids the asymmetric imbalance caused of traditional gimbal structure, extends working life.
The above embodiment is preferred embodiment of the present invention, not limits practical range of the present invention with this, therefore the equivalence change that all structures according to the present invention and material are done, all should be covered by protection scope of the present invention.
Claims (2)
1. an equalization type universal joint, it is characterized in that comprising left shell, ball core, right shell body, gland, described left shell, right shell body piece together housing entirety; Described left shell large footpath place toroidal surface is provided with a gland, and described gland is provided with screw, and described right shell body edge is corresponding is provided with screw, and described gland and right shell body are bolted to connection; Described ball core is arranged on housing whole interior and free to rotate, and the overall internal diameter of housing is slightly larger than described ball core external diameter.
