Mechanical seal stud torquing system by Maggie
Cartridge mounted mechanical seal for providing a seal between a housing and a rotatable shaft is provided, including at least one radial stud which extends from the inside of the rotary sleeve of the seal through the rotary sleeve and into the lock collar of the seal so as to transmit torque from the shaft to the rotating face of the seal.
Mechanical seals are used to provide a seal between various components on a rotating shaft. Such seals take many different forms. In the field of cartridge mounted seals are mechanical seals which have at least one set of contacting seal faces, one rotary face and one stationary face, the rotary face being driven by its connection to a sleeve which is mounted nonrotatably to the shaft. The entire cartridge seal unit is installed by simply sliding the sleeve and the attached seal components onto the shaft and fixing the sleeve in place. A gland plate is provided for supporting the stationary seal face. The gland plate is usually bolted to the housing (such as a pump housing) through which the shaft extends.
Cartridge mounted mechanical seals are shipped and installed as a unit. The rotary sleeve of the seal and the lock collar of prior art seals are held in place during shipment by temporary clips or cams, which work in conjunction with set screws which are threaded through holes in the lock collar and the sleeve. A typical arrangement is Cup point set screws extend through lock collar and sleeve.
Upon installation, cup point set screws dig into shaft, setting the seal in position. Although some seals have only cup point set screws to both set and drive the seal, this is not desirable. Dog point set screws having a blunt end are installed through holes in the lock collar and the sleeve. The hole in sleeve matingly receives the end of dog point screw. Thus, the lock collar receives torque from the cup point set screws and drives the sleeve via the dog point screws, protecting the cup point screws and threads from excessive wear. Dog point screws also provide a means for maintaining axial alignment of seal parts during shipment.
While the dog point set screws solve the problem of excessive wear of the cup point screws as well as maintain axial alignment, several other problems present themselves. It is difficult to determine from the exterior of the lock collar which screws are which, resulting in accidental loosening or tightening of the wrong screws. For example, a dog point screw 64 may be overtightened to the point where the blunt end of the screw abuts the shaft, causing the lock collar and/or the sleeve to bend. Further, during rotation of shaft 63 dog point screws may back out of their holes causing excessive torque to be transmitted to cup point screws, galling threads and damaging the seal. Also, should dog point screws be mistakenly removed or loosened during shipment, axial misalignment of the seal can result.
Accordingly, it is an object of this invention to provide a cartridge mounted mechanical seal with a means for transferring torque from a shaft to the rotary components of the seal without damaging fastener components, such as cup point set screws.
It is another object of this invention to provide a means for transferring torque from a shaft to the rotary components of the seal which maintains axial alignment of the seal prior to installation and during operation.
It is still another object of this invention to provide a means for transferring torque from a shaft to the rotary components of the seal which will not become disengaged during seal operation.
As can be seen, a stud torquing system is provided which protects threaded fasteners from damage during seal operation, and which maintains alignment during shipping. There are no screws which can be mistakenly tightened or loosened in the manner of dog point set screws. Other embodiments of the invention will occur to those skilled in the art, and are intended to be included within the scope and spirit of the following claims.
Therefore, an improved cartridge mounted mechanical seal for providing a seal between a housing and a rotatable shaft is provided, including at least one radial stud which extends from the inside of the rotary sleeve of the seal through the rotary sleeve and into the lock collar of the seal so as to transmit torque from the shaft to the rotating face of the seal.
