Description

1

The invention relates to mechanical engineering and can be used when installing a piston in a cylinder.

The purpose of the invention is to improve the reliability of the connection - ease of installation and disassembly.

FIG. i shows the connection in the assembly; in fig. 2 - locking ring element; in fig. 3 - split retaining ring.

The joint is dismantled by inserting the locking element 7 of the grippers into the windows 8 and then withdrawing the element 7 from the split stop ring 4. After the tabs are edited, the locking ring 5 element is reused.

The locking ring member is stamped from a steel sheet with a thickness of 1-2 mm depending on the diameter. The split stop ring is pulled out one-piece with the after-device. The shaft contains a shaft 1 with stops, on a 10-minute split cutter of thickness S on which part 2 is fixed. In the annular two halves.

The use of the device increases the reliability of the connection, it is small in size, vibration resistant and takes heavy loads, convenient for installation and removal.

The groove 3 of the shaft houses a split retaining ring 4. An intermediate element 5 is mounted on the shaft and in the groove of the fixed part to form an annular groove 6 between the mutually reversed side surfaces of the groove in the fixed part and the intermediate element. Kajačka 6 I-IMOLT is width n b and is directed at an angle axis to the axis of the device. The locking ring element 7 is made in the form of a cylindrical shell, for 20 degrees and against the shaft, containing

Claims (2)

Claim device A device for fixing a part, a retractable split ring placed in an annular groove of a shaft, and a locking ring element characterized in that, in order to increase the reliability of the axial fixation of the joint, the device is provided with pro-surfaces which have windows 9 with end deformable tabs 9 with one side and stubby collar 10 on the other hand. The entire connection is placed in cylinder 11. a stop split ring disposed in the annular groove of the shaft, and a locking ring member, characterized in that, in order to increase the reliability of the axial fixation of the joint, the device is equipped with the device assembled with the following intermediate element mounted on the shaft and groove of the fixed part with the formation of an annular groove between the mutually reversed side surfaces of the groove and the intermediate element, directed at an angle to the axis of the device, and the locking ring element is made in the form of a cylindrical shell with deformed front legs on one side and on the other hand, in this case the tabs are placed in said annular groove, and the collar of the locking ring element is in contact with the corresponding end of the split ring. at once. A fixed part (piston) is fixed to the shaft 1, then an intermediate element 5 is placed on the shaft 1 and in the groove of the part 9. In such a way that an annular groove 6 of width 6 is formed between the mutually reversed surfaces of the part 2 and the intermediate element 5. , directed at an angle a to the axis of the device. A slotted thrust ring 4 is installed in the annular groove 3 of the shaft 1. A locking ring element 7 is inserted onto it until it stops with a collar 10 at the corresponding end of the ring 4. The legs 9 of the locking element 7 enter the groove 6 and, deformed, embrace intermediate element 5, than provide self-fastening of the locking element 7 on the stop ring 4. The joint is dismantled by inserting the locking element 7 of the grippers into the windows 8 and then withdrawing the element 7 from the split abutment ring 4. After straightening the tabs, the locking ring element is reused. The locking ring member is stamped from a steel sheet with a thickness of 1-2 mm depending on the diameter. Cutting stop in focus on the shaft, containing Claims of the Invention A device for fixing a part, mounted in an emphasis on a shaft, comprising an abutting split ring disposed in the annular groove of the shaft, and a locking annular element characterized in that, in order to increase the reliability of the axial fixation of the connection, the device is provided with an intermediate member mounted on interstitial element mounted on the shaft and groove of the fixed part with the formation of an annular groove between the mutually reversed side surfaces of the groove and the intermediate element, directed at an angle to the axis of the device, and the locking ring element is made in the form of a cylindrical shell with deformed front legs on one side and on the other hand, in this case the tabs are placed in said annular groove, and the collar of the locking ring element is in contact with the corresponding end of the split ring. 2.
