Abstract
The utility model relates to a universal coupling, which is characterized in that two shaft sleeves are respectively arranged on two ends of a coupling shaft. Outer cylindrical faces of the two shaft sleeves are arranged with more than 8 indent arc grooves. The inner cylindrical face of a link-up coat engaged with a shaft sleeve is provided with more than 8 indent arc grooves. Steel balls are arranged in two corresponding arc grooves. The utility model has the advantages of reasonable design and simple structure. Due to the employment of an arc groove and a steel ball structure, the service life of the coupling is prolonged, the ability to carry large load of the coupling is enormously improved, and the operational reliability is improved.
Description
The utility model relates to a kind of coupling.
For many years in the axle connection process of China's automobile and metallurgical machinery drive part, the general cross-axle universal shaft coupling that adopts under the situation that the malalignment eccentric angle is bigger between axle and the axle, when adjusting malalignment passing shaft connects moment of torsion with axle in operation process, this product following main deficiency occurs and is in the long-term using process of Metallurgical Machinery Roller transmission device: a profile is irregular, is unfavorable for safety in production during running; Two, owing to blank temperature difference in the operation of rolling is big, torque load increases several times in a flash, and cross axle just two spindle noses of symmetry bears moment of torsion, ruptures easily when impact load increases suddenly; Three, maintenance cost height.
The purpose of this utility model is: a kind of greater impact load, novel steel ball Hooks coupling universal coupling that functional reliability is high of bearing is provided.
Its goal of the invention is achieved in that
Novel steel ball Hooks coupling universal coupling comprises joining shaft, connects overcoat and axle sleeve, and it is characterized in that: two axle sleeves are sheathed on the two ends of joining shaft respectively, the external cylindrical surface of axle sleeve axially go up uniform the inner concavity arc-shaped slot more than 8; An end that connects overcoat is set on the axle sleeve, connect overcoat axially the going up of inner cylindrical surface, with the axle sleeve fitting surface on corresponding uniform 8 above inner concavity arc-shaped slots; Connect in the overcoat arc-shaped slot corresponding and be respectively equipped with steel ball with axle sleeve.
Described novel steel ball Hooks coupling universal coupling is characterized in that connecting of two axle sleeves and joining shaft, and wherein one is that flat key connects, and another is a splined.
Described novel steel ball Hooks coupling universal coupling is characterized in that connecting on the axle sleeve in the outside, both sides of set steel ball in the overcoat arc-shaped slot corresponding with axle sleeve and is respectively equipped with back-up ring.
The utility model is reasonable in design, and is simple in structure.Owing to adopted curve bath and steel ball structure, in the use when joining shaft and axle are regulated the state of malalignment motion, steel ball forms axial rolling, steel ball bears under the situation of dynamic pressure and rolls, almost there is not the friction phenomenon, thereby be difficult for causing wearing and tearing, thereby realized prolonging the working life of coupling.On the other hand, adopt steel ball structure, driving torque is born by some steel balls, thereby has improved the ability that coupling bears big load greatly, has improved functional reliability.

Fig. 2 is connection jacket structure schematic representation,
Fig. 3 is Fig. 2 A-A sectional view,
Fig. 4 is the axle sleeve structure schematic representation,
Fig. 5 is Fig. 4 B-B schematic representation.
The utility model is further described below in conjunction with accompanying drawing.
Embodiment:
A kind of novel steel ball Hooks coupling universal coupling comprises joining shaft 3, connects overcoat 1 and axle sleeve 2.Two axle sleeves 2 are sleeved on the two ends of joining shaft 3 respectively by flat key 8, spline 9, the external cylindrical surface of axle sleeve 2 axially go up uniform 12 inner concavity arc-shaped slots; An end that connects overcoat 1 is sleeved on the axle sleeve 2, connect overcoat 1 axially the going up of inner cylindrical surface, with axle sleeve 2 fitting surfaces on corresponding uniform 12 inner concavity arc-shaped slots; Connect that each corresponding bar arc-shaped slot of overcoat 1 and axle sleeve 2 is interior to be installed with steel ball 4 respectively by back-up ring 7.One end of joining shaft 3 is installed with end cap 6, connects on overcoat 1 and the joining shaft 3 corresponding mounting ends end cap 5 is installed.
During use, the outer end that connects overcoat 1 connects with the axle for the treatment of transmission, and the interior steel ball 4 of connection overcoat 1 and the arc-shaped slot of axle sleeve 2 corresponding cooperations reaches the purpose of transmitting torque.When joining shaft and axle are regulated the state of malalignment motion, steel ball 4 forms axially and rolls, and steel ball rolls following of the situation of bearing dynamic pressure, can not produce the friction phenomenon, thereby can not occur wearing and tearing in using, thereby reach the purpose that increases the service life.
