| 8 | Field serviceable derailleur device | US09240827 | 1999-02-01 | US06447413B1 | 2002-09-10 | Eric S. Turer; Thomas J. Malay |
| A field serviceable device in conjunction with a pivoting means and a stationary means, such as a bicycle derailleur and a derailleur hanger, respectively. The device comprises a head, a barrel, a flange, and a pin. The barrel comprises a barrel-flange connector and barrel-pin connector on a first end, and a barrel-head connector on a second end. The head, flange, and pin are independently connected to the barrel. The pin has a pin-tool opening extending through the pin, and the barrel has a barrel-tool opening of sufficient dimension extending through the barrel such that a pin tool can extend into the barrel-tool opening without interference. The pin further defines a pin fracture notch that is designed to fracture before the pivoting means or stationary means is damaged due to a force applied to the pivoting means or stationary means by debris impacting the pivoting or stationary means or becoming wedged between, for example, the bicycle frame and the derailleur. The pin is designed such that the fractured pin is easily removed and replaced, without releasing the pivoting means from the head, barrel, and flange, thereby restoring the functionality of the pivoting and stationary means. | ||||||
| 9 | Axially frangible automatic torque limiting clutch | US389331 | 1989-08-03 | US4947972A | 1990-08-14 | Bruce K. Lea |
| A mechanical automatic torque limiting clutch containing an axially frangible and easily replaceable component is disclosed. The clutch is capable of limiting torque output by adjusting the friction between spring loaded input and output plates, and further is capable of preventing damage to other driveline components due to axial tension loads imparted to the driveline. The clutch allows a central axial bolt to break in tension should axial tension loads be applied which exceed the limits of the bolt, thereby protecting the remainder of the driveline components. When such a break occurs, the only damage done is to the bolt itself, which allows the input and output sides of the clutch to separate into two components which are quickly, easily and economically reassembled with a new bolt. Provision for weaker tensile loads is provided by use of bolts containing one or more grooves or indentations, which serve to reduce the cross sectional area and therefore the tensile strength of the bolt to the desired degree, or with a smaller diameter bolt and properly sized sleeves in order to prevent play between the bolt and axial bolt hole. | ||||||
| 10 | Overload control coupling between two rotating machine elements | US589547 | 1975-06-23 | US3975923A | 1976-08-24 | Karl Grimpe |
| An overload control coupling between two rotating machine elements, particularly the driving part and the driven part of a coaxial shaft mechanism with at least two essentially semi-cylindrical extensions radially arranged at the interface of the coupled machine elements and uniformly distributed over the circumference, the extensions each comprising portions from the coupled machine elements, which portions form cylinders having a separation plane or interface parallel with the rotation plane of the machine elements, the extensions being embraced by annular power-transmitting carrier links connecting the machine elements. In the case of overload, the machine elements may separate and disrupt the connection by the breaking of the carrier links at predetermined excessive stress levels. | ||||||

| 12 | Power transmission mechanism | US09601639 | 2000-08-04 | US06419585B1 | 2002-07-16 | Kazuya Kimura |
| An interruptible power transmission mechanism couples a drive source to a compressor. The power transmission mechanism has a pulley, which rotates in synchronism with the drive source, and a receiving member, which rotates in synchronism with the compressor. A limit spring couples the pulley and the receiving member such that they rotate together. When the load torque of the compressor exceeds a predetermined value, the diameter of the limit spring is decreased so that the limit spring engages a rib provided on the receiving member. Then, the deformation of the limit spring in the radial direction is locally restricted, causing stress at a specific portion of the limit spring to increase rapidly. As a result, the limit spring is reliably broken at a torque near the desired load torque, thus interrupting power in a desirable manner. | ||||||
| 13 | Decoupler shaft and air turbine starter having such a decoupler | US268311 | 1988-11-07 | US4871296A | 1989-10-03 | David L. Laessle; Todd S. Carlson; Andrew J. Krochmalny; Leroy C. Anderson |
| A torque limiting decoupler shaft transmits driving torque in a first sense without torque limiting action. However, torque applied to the shaft in a reverse sense opposite the driving torque results in an axial separating force between two portions of the decoupler shaft. When the reverse torque reaches a certain level a frangible tensile bar member fractures to permit decoupling of the shaft portions. A component of the shaft prevents undesirable recoupling of the shaft portions while also insuring that the relatively rotating portions of the shaft do not flail. An air turbine starter includes such a decoupler shaft. | ||||||
| 14 | Detachable overload control coupling between rotating machine elements | US936495 | 1978-08-24 | US4235082A | 1980-11-25 | Karl Grimpe |
| A safety coupling is provided for joining rotating machine parts, in which those portions of the coupling involving wear and which are subject to relative movement between the two joined parts are formed as detachable portions inserted into recesses in the joined parts. With this arrangement, the detachable parts may be removed for repair and/or replacement without involving the handling of the coupled rotating parts themselves, the latter of which may be large and unwieldy. | ||||||
| 15 | Coupling with overload safety device | US807339 | 1977-06-16 | US4097161A | 1978-06-27 | Hermann Weiss; Hans Wellkamp |
| A coupling apparatus where two coaxially held coupling halves are connected by a tensioning member provided with a predetermined breaking point. The tensioning member secured at one end to its associated coupling half, is radially and tangentially displaced with respect to the end of the tensioning member secured to the other coupling half. At the overload condition, one coupling half makes a complete rotation, after breaking, with respect to the other coupling half. A rotary escapement is provided as a holding structure so that when one element of the tensioning member swings, it does so out of the path of the other. | ||||||

| A device and method for providing mechanical protection, and in particular to a mechanical protection device including a transmission shaft with a resonant frequency in bending that corresponds to a predetermined rotary overspeed of the transmission shaft, the transmission shaft being insufficiently damped to avoid breakage of the transmission shaft as a result of the resonance in bending. In the mechanical protection method, the transmission shaft breaks as a result of this resonance in bending. | ||||||

| A torque limiting apparatus is located between a power source and a driven apparatus. A number of breakable power transmission members connect a drive rotor to a driven rotor. The breakable members are fractured to disconnect the driven rotor from the drive rotor when the load applied by the driven apparatus exceeds a predetermined value. A promoting member is located near at least one of the power transmission members for promoting breakage when the load causes the driven rotor to rotate relative to the drive rotor. The breakable members are broken consecutively. The breakable members are not significantly affected by fatigue. | ||||||
