Abstract
A method is provided for assembling a device in a preselected assembly position onto a rotatable shaft of a prime mover with respect to an opening in an end plate of the prime mover through which the shaft extends so as to preclude contamination of a lubricant in a lubrication system of the prime mover communicated with the opening in the event the prime mover is operated in an environment in which a fluid imcompatible with the lubricant may be presented to at least one of the end plate and an exterior end section of the shaft extending beyond the opening.
Claims16
A method of assembling a device having a sleeve section integral with a pair of opposite annular slingers in a preselected assembly position onto a rotatable shaft of a prime mover and with respect to an end plate of the prime mover and an opening in the end plate through which the shaft extends so as to preclude contamination of a lubricant in a lubricating system of the prime mover communicated with the opening in the event the prime mover is operated in an environment in which a fluid incompatible with the lubricant may be presented to at least one of the end plate and an exterior end section on the shaft extending beyond the opening, the method comprising the steps of:
- (a) arranging the sleeve section of the device generally in gripping engagement about the exterior end section of the shaft and moving the device on the exterior section toward the opening in the end plate;
- (b) inserting the sleeve section at least in part into the opening and locating one of the slingers over the opening and with respect to a raised part of the end plate disposed about the opening so as to define the preselected assembly position of the device and preclude the passage of any incompatible fluid across the end plate part into the opening and along the exterior end section of the shaft into the opening when the prime mover is operated in the environment of the fluid;
- and
- (c) predetermining the position of the other slinger on the shaft with respect to the opening and the lubrication system so that the other slinger is disposed in lubricant slinging relation with respect to a part of the lubrication system when the one slinger is located with respect to the raised part of the end plate during the inserting and locating step.
In a method of assembling a prime mover including a rotatable shaft with an end section thereof adapted for driving an apparatus and for subjection to leakage flow in the event of the occurence thereof from the apparatus of a fluid incompatible with a lubricant of a lubrication system in the prime mover to effect the lubrication of the shaft, at least one end plate with an opening therein extending about the shaft and communicated with the lubrication system, and means for preventing passage of the lubricant and the fluid through the opening, the method comprising the steps of:
- associating the passage preventing means about the end section of the shaft;
- moving the passage preventing means along the end section of the shaft toward the at least one end plate;
- and
- disposing the passage preventing means in an assembly position with respect to the shaft and the at least one end plate so that a part of the passage preventing means is arranged with respect to the opening for interrupting lubricant flow upon the occurence thereof generally along the shaft toward the opening and also so that another part of the passage preventing means is arranged with respect to the opening for interrupting leakage fluid flow in the event of the occurence thereof generally along the end section of the shaft toward the opening.
A method of assembling a device onto a rotatable shaft of a prime mover having an end plate with an opening therein through which an end section of the shaft extends exteriorly of the prime mover so as to preclude contamination of a lubricant in a lubrication system of the prime mover in the event the prime mover is operated in an environment in which a fluid incompatible with the lubricant may be presented to at least one of the end section of the shaft and the end plate, the method comprising the steps of:
- engaging the device in gripping relation about the end section of the shaft;
- sliding the device on the end section of the shaft and in the gripping engagement relation therewith toward the opening in the end plate;
- inserting the device in part into the opening in the end plate;
- and
- arranging the device in a preselected assembly position on the shaft with one of a pair of flanges integral with the device extending adjacent the end plate over the opening so as to preclude the passage of any incompatible fluid both along the end plate and the end section of the shaft into the opening when the prime mover is operated in the environment of the incompatible fluid and with the other of the flanges disposed with respect to the opening and the lubrication system so as to preclude the passage through the opening of lubricant flowing from the lubrication system along the shaft toward the opening when the prime mover is operated.
