Supplement lubricant free pneumatic motor

Abstract

The present invention provides a pneumatic motor having a motor body having an air inlet and an air outlet, at least one rotor mounted in a chamber of the motor body and adapted to be driven by compressed air fed into the air inlet and an adhesive lubricant applied to the at least one rotor, the lubricant being sufficiently adhesive to remain substantially adhered to the at least one rotor under operational speeds in excess of 13500 rpm.

1 . A pneumatic motor having:
 a motor body having an air inlet and an air outlet;   at least one rotor mounted in a chamber of said motor body and adapted to be driven by compressed air fed into said air inlet; and   an adhesive lubricant applied to said at least one rotor, said lubricant being sufficiently adhesive to remain substantially adhered to said at least one rotor under operational speeds in excess of 13500 rpm.   
   
   
       2 . The motor of  claim 1 , wherein said at least one rotor includes a drive rotor and an idler rotor. 
   
   
       3 . The motor of  claim 1 , wherein said rotors are mounted on sealed cage deep groove ball bearings. 
   
   
       4 . The motor of  claim 1 , wherein said motor body is constructed from corrosion resistant material. 
   
   
       5 . The motor of  claim 1 , wherein said motor further includes a reduction gearbox having a gearbox body constructed from corrosion resistant material. 
   
   
       6 . The motor of  claim 4  wherein the corrosion resistant material comprises nylon, stainless steel or acetyl resin engineering plastic. 
   
   
       7 . The motor of  claim 1 , wherein the motor is adapted for bidirectional rotation and the air inlet and air outlet are selectively interchangeable. 
   
   
       8 . The motor of  claim 1 , wherein said motor body includes internal baffling formed in said motor body and associated with said air outlet, said baffling being adapted to muffle motor noise. 
   
   
       9 . The motor of  claim 8 , wherein said motor body comprises a wall surrounding said chamber and wherein said baffling is provided in a conduit formed o within said wall, said conduit providing fluid communication between said chamber and said air outlet. 
   
   
       10 . The motor of  claim 9 , wherein said baffling is provided by said conduit following a corrugated path within said wall. 
   
   
       11 . The motor of  claim 9 , wherein said conduit extends around said wall, substantially circumventing said chamber. 
   
   
       12 . The motor of  claim 1 , wherein the adhesive lubricant is Optimol Paste White T Spray (trade mark).
