Vane motor

A method to lubricate a vane motor, the vane motor including a rotor body driven by compressed air with vane gaps for radially movable vanes, and a rotor shaft for rotatably bearing the rotor body relative to a motor bushing, wherein the rotor shaft is designed as a hollow shaft with a first lubricant reservoir in the interior, wherein the first lubricant reservoir has a lubricant filling opening accessible from outside of the vane motor, wherein at least one of the first lubricant reservoir is connected by at least one radial lubricant hole to at least one further lubricant reservoir arranged in a section of the rotor body between two vane gaps, or the first lubricant reservoir is connected to an outlet opening of at least one further lubricant reservoir arranged in one of the vane gaps for supplying lubricant into the vane gap, and wherein the first lubricant reservoir is provided to receive and to store lubricant, and is formed so that there is no continuous supply of lubricant while the vane motor is operating, the method comprising the steps of:

• connecting a lubricant press to a lubrication nipple arranged on the rotor shaft of the vane motor accessible from the outside of the vane motor,
• pressing lubricant into at least the first lubricant reservoir arranged in the rotor shaft provided to receive and to store the lubricant,
• detaching the lubricant press from the lubrication nipple, and
• operating the vane motor, wherein the lubricant is discharged out of the first lubricant reservoir through at least one outlet opening of the at least one further lubricant reservoir onto the surface of the rotor body and into a vane gap of the rotor body by the rotation of the rotor body and the rotor shaft,
• wherein there is no continuous supply of lubricant while the vane motor is operating.
