Abstract
An endless power transmission belt made primarily of elastomeric materials is provided and comprises a plurality of laterally spaced belt elements which are interconnected by a tie band with the belt elements each having a tension section, a load-carrying section, and a compression section and each of the elements has a plurality of teeth defined in its compression section with the teeth in each belt element being staggered relative to teeth in an immediately adjacent belt element.

An endless power transmission belt for operation in an endless path comprising a plurality of laterally spaced belt elements and a tie band interconnecting said belt elements, each of said elements comprising, a tension section, a load-carrying section, and a compression section, each of said elements having a plurality of teeth defined in its compression section, said teeth in each belt element being staggered relative to teeth of an immediately adjacent belt element, said teeth providing optimum flexibility for said belt characterized by a substantially uniform bending modulus, said staggered relation of the teeth assuring the belt is free of hinge points and also assuring quieter operation thereof in associated sheaves.
An elastomeric endless power transmission belt for operation in an endless path and made primarily of an elastomeric material with the belt comprising a plurality of laterally spaced belt elements and a tie band interconnecting said belt elements, each of said elements comprising a tension section, a load-carrying section, and a compression section, each of said elements having a plurality of teeth defined in its comression section by a plurality of machined grooves in each comression section extending transverse the endless path of said belt, said teeth in each belt element being staggered relative to the teeth of an immediately adjacent belt element, said teeth providing optimum flexibility for said belt characterized by a substantially uniform bending modulus, said staggered relation of the teeth assuring the belt is free of hinge points of substantially reduced thickness and also assuring quieter operation thereof in associated sheaves.
A method of making an elastomeric endless power transmission belt for operation in an endless path and made primarily of an elastomeric material comprising the steps of;
- building a plurality of laterally spaced belt elements with each element having a tension section, a load-carrying section, and a compression section;
- interconnecting said elements together with a tie band;
- and forming a plurality of teeth in the compression section of each belt element by forming grooves therein so that said teeth in each belt element are staggered relative to the teeth of an immediately adjacent belt element;
- said teeth providing optimum flexibility for said belt characterized by a substantially uniform bending modulus with said staggered relation of the teeth assuring the belt is free of hinge points of substantially reduced thickness and also assuring quieter operation thereof in associated sheaves.
