Description

The invention relates to mechanical engineering and is intended to connect hollow cooled shafts in stands, jigs, etc.

The closest to the invention according to the Technical essence and the achieved effect is the connection of shafts, containing two shafts, connected by segments in contact with flats, made on the driven shaft C.

The disadvantage of this connection is that it cannot connect hollow shafts, cooled with liquid and subjected to thermal expansion and compression.

The purpose of the invention is to expand the operational capabilities by creating a hermetic rolling joint that transmits torque.

For this purpose, the shaft connection, containing two shafts connected by segments in contact with the flips, is provided with a fixing spring permitted ring, the drive shaft covers the driven one and is made with end slots, the segments are made with corners that enter the end slots of the drive shaft.

FIG. 1 shows a connection with a longitudinal section, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 - raarez bb in fig. one; in fig. 4 shows a section of a CC in FIG. one.

The shaft connection contains hollow shafts -1 and 2. At the end of the driven shaft, in the grooves of shaft 1, O-rings 3 are installed to prevent leakage.

10 working medium, behind which are made the flats 4 with shoulder 5, limiting the longitudinal movement of the shafts. on the flats rests on the surface ft (the gap is shown conventionally) segment 6,

15 on the convex surface 7 of which there is a barb line 8, which enters the slot 9 of the shaft 2. Convex, the surface 7 enters the recess 10 to prevent it falling out of the slots during the longitudinal movement of the shafts. The segments are fixed spring split ring 11 mounted in the groove 12 of the shaft 2.

The assembly and operation of the device is carried out as follows.

On shaft 1, seals are mounted in grooves e. rings 3. Then the shaft 1 is inserted into the undercut 10 of the shaft 2, after which they are inserted into the

30 slots 9 segments 6. Next, the split ring 11 is inserted into the groove 12, the assembly is completed.

The rotation from the shaft 2 through the slot 9, the tendril 8 of the segment, the surface of the segment b and the flats 4 is transmitted to the shaft 1. During the rotation, the shafts can move relative to each other by the value L. The connection allows the shafts to move from one another to another. work time, and. flow inside the coolant.
