An overload protection device in combination with a prime mover and gearbox transmission supplies torque through a gearbox transmission to a load. An input shaft with is driven by the prime mover and rotates therewith. An external spline on the input shaft mates with an input gear having an internal spline. Upon overload of the gearbox transmission, the input shaft fractures an annular groove in the input shaft. A bushing prevents travel of the portion of the input shaft which is driven by the prime mover and which continues to spin after the fracture.

Absolute counters for linear segments or revolutions having a Wiegand element (WE) in the main field between two opposite excitation magnets (EM1, EM2) connected by a common ferromagnetic back connection body (14), and an additional sensor element (SE) for determining the information about the polarity and the position of the excitation magnet, wherein the output signals of the Wiegand element (WE) simultaneously supplies energy for the required counter and logic electronics, as well as having an additional sensor (ZS) for the fine resolution in the frame work of a multi-turn which also lies within the main field between the excitation magnets (EM1, EM2).

Arrangement with a locking element for an imaginary mechanical locking arrangement, consisting of the locking element (2) and a locking hook (3) whose hooked part can be connected with the locking element to close the lock. The locking element (2) is part of a single-part or two-part elongated body (4) consisting of curved and/or straight sections. The locking element (2) is located in the recess (6) of a plastic body (5). The parts of the elongated body (4) lying beyond the locking element (2) are, for the most part, embedded in the plastic body (5), where the direction of at least one of these embedded sections is towards the interior of the plastic body (5).

Lubricating oil is forced and pumped into and through the first passageway through the floating ring gear and into the annulus between the gearbox housing and the floating ring gear. Lubricating oil from the annulus is pumped into and through the second passageway and through the joint between the second and third passageway, and through the third passageway into the void in the cover. Thereafter the oil passes through the fourth passageway between the void in the cover and the circumferential recess in the cover and lubricating the bearing mounted adjacent the recess in the cover/housing.

A method for testing a plurality of fire hoses having respective service test pressures and the test apparatus therefor wherein each hose is required to maintain a test pressure for a specified duration to pass the test. The test pressure is proportional to the service test pressure. Each hose is coupled to a respective hose fitting of a respective branch test conduit. Each branch test conduit includes an isolation valve, a pressure transducer, and a hose fitting downstream of the isolation valve. A variable frequency-variable speed controls a motor which drives a positive displacement water pump supplying water to and pressurizing a water header conduit and a plurality of branch test conduits interconnected therewith. An algorithm applied to the error signal for a respective hose line generates a pump speed command limited by the controller to regulate the rate of increase of pump output pressure.
摘要:
The invention relates to a sensor arrangement for scanning a scanning area (16, 36) comprising a scanner (10, 30, 42, 54) that generates a scanning field (12) which is defined between two legs spaced from each other by a scanning angle (A), and which scanner is adapted to control at least one blocking means (18, 38, 50) for a passageway (32, 56), said passageway (32, 56) being delimited at least in its horizontal extension. The invention is characterized in that a scanner (10, 30, 42, 54) is mounted at a distance, as viewed in the passage direction (14), from the passageway (32, 56) and thus also from the controlled blocking means (18, 38, 50), and that the scanning field (12) is directed towards the passageway and extends through the passageway (32, 56).

The invention relates to an actuator (10) for controlling a fluid flow which comprises a valve housing (11), a flow restrictor (18) and a valve seat (16), in which the flow restrictor (18) is designed such that the flow restrictor (18)—together with a closure (22) which is connected to the valve housing (12)—will form a pressure-relieving chamber (28), and as a result, a relative movement of the flow restrictor (18) and the chamber closure (22) together with the actuation will cause the volume of the pressure-relieving chamber (28) to change as a function of the direction of movement, and the flow restrictor (18) has a recess (24) which will allow the fluid to be controlled to flow into the pressure-relieving chamber (28). The invention is characterized in that the seal (26, 30) between the flow restrictor (18) and the valve housing (11) is designed such that, in the closing position, with the flow restrictor (18) resting tightly on the valve seat (16), the seal (26, 30) will have a sealing effect, and with the flow restrictor (18) not resting on the seat, the seal (26, 30) will allow a defined amount of fluid from the pressure-relieving chamber (28) to pass through.
摘要:
A hinge has a pivoting leaf (2) and a fixed leaf (3), a hollow axle (7) fixedly connected to the pivoting leaf and rotatably connected to first and second journal bearings (5-1, 5-2) of the fixed hinge leaf, a spiral torsion spring (8) arranged in the hollow axle. One end of the spring is fixed to the hollow axle and the other end of the spring is fixed to a worm wheel (9) that is arranged in the first journal bearing. An endless screw (6) resides in the first journal bearing and engages with the worm wheel. Rotation of the endless screw drives the worm wheel and the spiral torsion spring to rotate, thereby adjusting the tension of the spring.
摘要:
The releasable locking arrangement for two components consists of a hook-connecting element arranged on a first component (10) and a spring-loaded locking hook (26) with swivelling axis (22) arranged on a second component (20). The locking hook (21) and the hook-connecting element can be connected with one another to form the lock. The hook-connecting element on the first component (10) is a retaining rod (11) whose ends are movable in a guide track (12, 12′). The swivelling axis (22) of the locking hook (21) on the second component (20) is connected with a holder (27). The holder (27) has a sliding bevel (24-S, 25-S) for the retaining rod (11). When the two components (10, 20) approach one another, the retaining rod (11) slides upwards on the sliding bevel (24-S, 25-S) of the holder. This causes the retaining rod to move in its guide track (12, 12′) at the same time.
