Low slip belt drive

Claim 2

A belt drive for converting unsteady rotary movements of a drive wheel which alternate in their direction of rotation into corresponding translatory movements, which includes: drive wheel means, driven wheel means, a finite relatively thin preloaded steel belt looped around said driving and driven wheel means and having its ends arranged in spaced relationship to each other, and tensioning means comprising damping means interposed between and connected to the ends of said belt and adapted to dampen vibrations originating with said steel belt and said driving wheel means, said tensioning means forming a belt lock.

Claim 3

A belt drive according to claim 1, in which the steel belt is of spring steel and has a maximum thickness of 0.2 mm.

Claim 4

A belt drive according to claim 1, in which said drive wheel means has a surface of high static fricTion engaged by said steel belt while the latter is under relatively high preload.

Claim 5

A belt drive according to claim 1, in which the ratio of the width of the steel belt to the thickness thereof is at least 50:

Claim 6

A belt drive according to claim 1, in which said belt lock includes elastic means having high self-damping characteristics.

Claim 7

A belt drive according to claim 5, in which said elastic means are readily exchangeably arranged.

Claim 8

A belt drive according to claim 1, in which the belt lock includes first means carrying a pointer, and second means elastically connected to said first means and carrying a scale, said pointer and said scale being movable relative to each other during the setting of the desired preload to be impacted upon said steel belt to thereby indicate the respective preload imparted upon the belt.

Claim 9

A belt drive for converting unsteady rotary movements of a drive wheel which alternate in their direction of rotation into corresponding translatory movements, which includes: drive wheel means, driven wheel means, a finite relatively thin preloaded steel belt looped around said driving and driven wheel means and having its ends arranged in spaced relationship to each other, and tensioning means comprising damping means interposed between and connected to the ends of said belt and adapted to dampen vibrations originating with said steel belt and said driving wheel means, said tensioning means including elastic means formed by combination rubber-metal vibration damping means.

Claim 10

A belt drive for converting unsteady rotary movements of a drive wheel which alternate in their direction of rotation into corresponding translatory movements, which includes: drive wheel means, driven wheel means, a finite relatively thin preloaded steel belt looped around said driving and driven wheel means and having its ends arranged in spaced relationship to each other, and tensioning means comprising damping means interposed between and connected to the ends of said belt and adapted to dampen vibrations originating with said steel belt and said driving wheel means, said tensioning means including elastic means formed by combination rubber-metal vibration damping means.

Claim 11

A belt drive for converting unsteady rotary movements of a drive wheel which alternate in their direction of rotation into corresponding translatory movements, which includes: drive wheel means, driven wheel means, a finite relatively thin preloaded steel belt looped around said driving and driven wheel means and having its ends arranged in spaced relationship to each other, and tensioning means comprising damping means interposed between and connected to the ends of said belt and adapted to dampen vibrations originating with said steel belt and said driving wheel means, said tensioning means including a plurality of rubber elements arranged in parallel to each other and having vibration damping characteristics.

Claim 12

A belt drive for converting unsteady rotary movements of a drive wheel which alternate in their direction of rotation into corresponding translatory movements, which includes: drive wheel means, driven wheel means, a finite relatively thin preloaded steel belt looped around said driving and driven wheel means and having its ends arranged in spaced relationship to each other, and tensioning means comprising damping means interposed between and connected to the ends of said belt and adapted to dampen vibrations originating with said steel belt and said driving wheel means, said tensioning means including a plurality of rubber elements arranged in parallel to each other and having vibration damping characteristics.

Claim 13

A belt drive according to claim 9, in which said rubber elements are so arranged as to be subjected to shearing stresses which act in the direction of the pulling forces active in the belt during the operation of the latter.

Claim 14

A belt drive for converting unsteady rotary movements of a drive wheel which alternate in their direction of rotation into corresponding translatory movements, which includes: drive wheel means, driven wheel means, a finite relatively thin preloaded steel belt looped around said driving and driven wheel means and having its ends arranged in spaced relationship to each other, and tensioning means comprising damping means interposed between and connected to the ends of said belt and adapted to dampen vibrations originating with said steel belt and said driving wheel means, a mass and additional damping means interposed between and connected to said mass and said steel belt.
