Sealed Disposable Concrete Vibrator

A sealed disposable concrete vibrator assembly, comprising:

• a hollow cylindrical main housing enclosing a shaft rotationally supported by bearings, the shaft having an eccentric mid portion rotatable within the main housing;
• an adaptor housing having a cylindrical protrusion having an outer surface configured to frictionally engage a proximal end of the main housing and having an inner surface configured to frictionally engage one or more of the bearings;
• a tip cover having a cylindrical protrusion having an outer surface configured to frictionally engage a distal end of the main housing and having an inner surface configured to frictionally engage one or more of the bearings;
• an oil seal compressed against a flange integral to the adaptor housing;
• and
• a circumvolving adaptor coupled through the oil seal to a driven end of the shaft.

A method for manufacturing a sealed disposable concrete vibrator, comprising steps for:

• providing a main housing having open proximal and distal ends;
• providing a tip cover having a bearing channel and having an attachment sleeve configured to frictionally engage the distal end of the main housing;
• fitting one or more bearings within the bearing channel of the tip cover;
• attaching the attachment sleeve of the tip cover to the distal end of the main housing;
• providing an adaptor housing having a bearing channel, and having an attachment sleeve configured to frictionally engage the proximal end of the main housing;
• fitting one or more bearings within the bearing channel of the adaptor housing;
• installing a driven end of an eccentric shaft concentrically through the one or more bearings of the adaptor housing;
• coupling a drive shaft adaptor to the driven end of the eccentric shaft;
• installing a nondriven end of the eccentric shaft within the one or more bearings of the tip cover;
• and
• attaching the attachment sleeve of the adaptor housing to the proximal end of the main housing.
