Abstract
A platform mounted drive train for a professional carpet and floor cleaner system, the platform mounted drive train being formed of a rigid platform; a power plant having two spaced apart mounting structures secured to the rigid platform; a vacuum blower having one mounting structure secured to the rigid platform; a rigid structural connector coupled between the power plant and the vacuum blower for rigidly securing the vacuum blower in fixed lateral, angular and rotational alignment with the power plant; and a coupler assembly interfaced between an output drive of the power plant and an input drive of the vacuum blower. The drive train is optionally mounted using one or more vibration isolators.
Claims22
A cleaning system having a rigid drive system mounted on a rigid structural frame with a three-point mount and coupled for generating vacuum in a water recovery tank, a high pressure solution hose between a supply of heated and pressurized water-based chemical cleaning solution and a delivery wand for providing the cleaning solution to a target surface, and a vacuum hose for recovering previously delivered cleaning solution from the target surface using the vacuum generated by the drive system, wherein the rigid drive system includes a torque generator having a torque output shaft and a vacuum generator having a torque input shaft, a rigid metal-to-metal structural connector secured between the torque generator and vacuum generator, a coupler assembly coupled for transmitting torque from the torque output shaft of the torque generator to the torque input shaft of the vacuum generator, the three-point mount comprising:
- at least two spaced apart mounting structures on opposite sides of the torque generator;
- at least one mounting structure on an external surface of the vacuum generator forming a triangular pattern with two of the spaced apart mounting structures;
- and
- means for securing to the rigid structural frame at exactly the three mounting structures that form the triangular pattern.
An industrial substrate cleaning system, comprising:
- a means for delivering heated and pressurized water-based chemical cleaning solution to a target substrate;
- a means for recovering previously delivered cleaning solution from the target substrate using vacuum;
- a drive means comprising:
- a torque generating means having a torque outputting means,
- a vacuum generating means having a torque inputting means,
- a means for rigidly coupling the vacuum generating means to the torque generating means in a single structural drive unit, and
- a means for interfacing the torque inputting means of the vacuum generating means to the torque outputting means of the torque generating means;
- and
- a means for securing the single structural drive unit to a rigid platform in a substantially triangular mounting pattern.
An industrial substrate cleaning system, comprising:
- a water pump;
- a solution hose coupled between the pump and a delivery wand for delivering a pressurized water-based chemical cleaning solution to a target substrate;
- a rigid structural platform;
- a rigid drive system, comprising:
- a torque generator secured to the rigid structural platform at exactly two spaced apart positions, the torque generator comprising a torque output shaft,
- a vacuum generator spaced apart from the torque generator and secured to the rigid structural platform at exactly one position that is spaced apart from the two positions whereby the torque generator is secured and forming a substantially triangular mounting pattern therewith, the vacuum generator comprising a torque input shaft,
- a rigid structural connector rigidly coupling the vacuum generator to the torque generator in a substantially monolithic structural drive unit, and
- a coupling interfacing the torque input shaft of the vacuum generator vacuum generator to the torque output shaft of the torque generator;
- a recovery tank for recovering previously delivered cleaning solution from the target substrate;
- and
- a vacuum hose coupled between the recovery tank and the vacuum generator for generating vacuum in the recovery tank.
