Abstract
Method for increasing the torque generating capabilities of a clutch are disclosed including the application of a film lubricant composition onto the engagement surfaces of a clutch. The composition imparts anti-galling properties to engaging surfaces of metallic pieces such as brakes or clutches.
Claims19
A process for increasing the torque of metallic surfaces that engage, comprising:
- applying a film lubricant composition onto the engagement surfaces of the clutch, said film lubricant composition comprises a sulfate, an alkali metal silicate and a phosphate;
- and
- engaging the surfaces thereby increasing the torque of the metallic surfaces,
- wherein the film lubricant is an anti-galling composition comprised of the following components:
- ______________________________________ alkali-hydroxide 5-20% by weight alkali sulfate 0.5-5% alkali phosphate 5-20% alkali silicate 5-20% a polymeric water soluble material 5-15% water 40-60% 100% ______________________________________
2 more elements
A process for increasing the torque of a clutch having engagement surfaces, comprising:
- cleaning at least one of the engagement surfaces of the clutch;
- heating the engagement surfaces;
- applying a film lubricant composition onto the engagement surfaces of the clutch, said film lubricant composition further comprises a sulfate, an alkali metal silicate and a phosphate;
- and
- cooling the engagement surfaces,
- wherein the film lubricant is an anti-galling composition comprised of the following components:
- ______________________________________ alkali-hydroxide 5-20% by weight alkali sulfate 0.5-5% alkali phosphate 5-20% alkali silicate 5-20% a polymeric water soluble material 5-15% water 40-60% 100% ______________________________________
4 more elements
A process for increasing the torque of a clutch having engagement surfaces comprising:
- washing the engagement surfaces of the clutch;
- drying the engagement surfaces;
- submerging the engagement surfaces in a film lubricant, said film lubricant composition further comprises a sulfate, an alkali metal silicate and a phosphate;
- cooling the engagement surfaces;
- and
- drying the engagement surfaces,
- wherein the film lubricant is an anti-galling composition comprised of the following components:
- ______________________________________ alkali-hydroxide 5-20% by weight alkali sulfate 0.5-5% alkali phosphate 5-20% alkali silicate 5-20% a polymeric water soluble material 5-15% water 40-60% 100% ______________________________________
