Abstract
A power transmission belt having a body with an inside, an outside, and a length. The body has a tension section and a compression section, and teeth and troughs alternating lengthwise of the body. A layer on the body in which the teeth are formed has a surface facing in one of an inside and outside direction on which alternating protrusions and recesses are formed against which another component on the body is placed and conforms.
Claims12
A power transmission belt comprising:
- a body with an inside, an outside, and a length,
- the body having a tension section and a compression section,
- the body having teeth and troughs alternating lengthwise of the body,
- a layer on the body in which the teeth are formed having a surface facing in one of an inside and outside direction on which alternating protrusions and recesses are formed against which another component on the body is placed and conforms.
The power transmission belt according to claim 3 wherein the protrusions have a dimension between the inside and outside of the body between 0.2 and 2.5 mm.
A power transmission belt comprising:
- a body with an inside, an outside, and a length,
- the body having a tension section and a compression section,
- the body having teeth and troughs alternating lengthwise of the body,
- a layer on the body having oppositely facing first and second surfaces,
- the teeth and troughs formed at the first surface by applying pressure to the layer against a mold surface to cause the first surface to conform to a mold surface that has a shape complementary to the teeth and troughs,
- the body further comprising a component that is placed directly against the second surface of the layer,
- the second surface of the first layer not having any discrete holes at the teeth, generated by conforming of the first layer to a mold surface into which the component is directed.
