Locking mechanism for agitator seal, and its dismounting method

Abstract

The invention discloses a locking mechanism for agitator seal and its dismounting method. The locking mechanism comprises a locking sleeve, a snap ring, a driving ring, a split ring, a first bolt, a second bolt, a first nut, a second nut and a third nut, wherein one end of the locking sleeve is mounted between a shaft sleeve and a shaft, the outer end face of the other end of the locking sleeve is provided with a threaded hole and a threaded through hole, the first bolt is mounted on the threaded through hole and abutted against a shaft sleeve accessory, the driving ring is mounted on the shaft via the open structured snap ring, the split ring is mounted at the outer end face of the driving ring, the driving ring and the split ring are provided with a first smooth hole and a second smooth hole corresponding to the threaded hole of the locking sleeve, the second bolt passes through the second and the first smooth hole to get mounted in the threaded hole of the locking sleeve, the first, second and third nuts are mounted on the second bolt, the first nut is located at the outer end face of the locking sleeve, the second nut is located at the inner end face of the driving ring and the third nut is located at the outer end face of the split ring. Advantages of the invention include simple structure, convenient dismounting, good labor-saving and time-saving effects and high reliability.

Description

technical field [0001] The invention relates to the field of mechanical seals, in particular to a locking mechanism for stirring seals and a disassembly method thereof. Background technique [0002] The main characteristics of stirring mechanical seals are: low speed, large shaft diameter, and large transmission torque required for sealing. The locking device is a device that must be used for stirring mechanical seals. The torque drives the seal to rotate, and there are many kinds of locking devices for stirring and sealing. According to different actual conditions, the locking methods are also different. Some locking devices currently in use are inconvenient to disassemble and have low reliability. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned disadvantages and provide a locking mechanism for stirring and sealing and a method for disassembling and assembling thereof. [0004] The technical solution adopted by th...
