Application Requirements

This article presents a review on two conveyors at the Ford Motor Co.’s Wayne, MI, assembly plant that use the same technology to meet two very different requirements. One system handles fully dressed, pallet-mounted engines in packages weighing up to 1600 pounds, while the other deals with pallet-mounted instrument panels having a total package weight of 80 pounds. The conveyors, supplied by Bleichert Inc. of Sterling Heights, Mich., use a roller drive mechanism that allows them to adapt to the different application requirements. Ford accomplishes the engine/chassis marriage by lifting completely dressed engines into the vehicle from below. The pallet-mounted engines are transported on a cart, called a moon buggy by Wayne plant personnel. The drive motor can be positioned anywhere along the length of the conveyor. It uses a gear reducer and timing belt to transmit power to the driveshaft. Each of the one-meter-long driveshaft sections is linked to the next one by a coupling to complete the modular drive system.

Static Conditions

Helical timing belts have been developed in order to reduce the noise that occurs when conventional timing belts are driven. Helical timing belts are characterized by synchronous rotation. Although several studies have been performed to clarify the noise characteristics and belt life of helical timing belts, the transmission error of these belts remains unclear. In the present study, the transmission error having a period of one pitch of the pulley was investigated both theoretically and experimentally for helical timing belt drives. Experimental conditions were such that the transmission force acts on the helical timing belts under quasi-static conditions and the belt incurs belt climbing at the beginning of meshing and at the end of meshing. Experimental results obtained for the transmission error agreed closely with the computed results. The computed results revealed that helical timing belts can be analyzed as a set of very narrow belts for which the helix angle is zero. The transmission error was found to decrease when the helix angle or the belt width increase within a range defined such that the face advance is less than one belt pitch. In addition, there exists an appropriate installation tension that reduces the transmission error.

The paper deals with the problem of timing belt pitch significance for the dynamics of a timing belt transmission gear motion. Specific pitches of timing belts have been used for many years. They were previously reserved for belts made of rubber, while another group of pitches was intended for belts made of polyurethane. This division ceased to apply recently, and in addition there are belts with pitches which have not been used before, such as HTD9M or AT15. The paper presents the parameter that makes the pulley diameter and the pitch dependent on the number of teeth involved in meshing (coupling) with a pulley. It is an equivalent of the coverage factor occurring in cylindrical timing gears. Earlier studies on that parameter did not take into account the teeth unevenly spaced over the width of the belt. New pitches of belts may occur in "mass production" applications and they are applied more and more often. Thus it is important to bear in mind the consequences of changing the pitch of the timing belt in transmission gear structures.
