A malfunction diagnosis apparatus for a gear motor includes a vibration sensor portion, and a diagnosis unit that determines whether or not an abnormality occurs in the gear motor based on vibration detected by the vibration sensor portion. The vibration sensor portion and the diagnosis unit are installed in the gear motor. The diagnosis unit has a control power source which supplies power to the vibration sensor portion. The vibration sensor portion outputs detected vibration data to the diagnosis unit in a digital format.

The application relates to a device for conveying a medium having a working machine (2) and multiple carrier shafts (25, 35) with transport elements (22, 32) for the medium to be conveyed arranged on them, along a drive (3) that sets the carrier shafts (25, 35) in rotation, wherein the drive (3) has multiple driven shafts (20, 30), each of which is coupled with not less than one carrier shaft (25, 35).

A rotary engine, parts thereof, and methods associated therewith is provided. The engine is modular and adjustable to accommodate a variety of requirements and preferences. The system includes a combustion assembly having a housing and a power rotor positioned therein. The power rotor rotates in a first direction from the beginning of each combustion process through the end of each exhaust process. The system also includes a compression assembly linked to the combustion assembly such that the compression rotor rotates in the first direction from the beginning of each intake process through the end of each compression process. A tank assembly in fluid communication with the compression assembly and the combustion assembly provides stability to the system while eliminating or otherwise reducing transitional loses.

Provided is a gear pump or a motor provided with: a casing internally provided with a gear housing compartment in which a pair of gears are housed; a side plate interposed between the casing and the gears; and a gasket which is disposed on a non-slide surface, and which divides a space between the non-slide surface and the casing into a high pressure side and a low pressure side. The gear pump or the motor is configured such that, in order to discover early the mounting of the side plate in a wrong attitude, such as the upper and lower sides thereof being reversed or the high pressure portion side and the low pressure portion side being reversed, flow rate efficiency is decreased when the side plate is in an attitude other than a predetermined attitude, compared to when the side plate is in the predetermined attitude.
