Rotary eccentric loads often lead to vibration problems in motors, which may reduced their reliability and operating life. In order to reduce the radial vibration in permanent magnet motors, a real time detection method for rotary eccentric load based on the theoretical analysis of the motor vibration and the mechanical analysis was given, and a novel control strategy based on FOC (field ...

The swinging system, consisting of a low-speed motor, worm gear reducer, eccentric wheel, swing link, and a bracket, drives the fan to reciprocating swing of 3–4 times/minute within 0–90°. The elevation angle bracket installed under the fan, according to the environmental condition, can …
Linkage drive— Attempting to maximize stroke rates using crank- or eccentric-drive systems requires increasing the slide speed. However, when deep drawing, ram speed typically must not exceed 0.4 to 0.5 m/sec. during deformation. A linkage-drive system can be designed for mechanical presses so that slide speed during drawing can be reduced by ...
In the preferred embodiment, the eccentric drive system includes a drive shaft, a relatively large eccentric weight rigidly mounted along a central region of the drive shaft, and a pair of smaller weights disposed at opposite ends of the central weight and rotatably mounted on the drive shaft. A notch is formed in each of the smaller weights.
drive system. Two pinions, each mounted on the output shaft of separate, identical worm gear reducers, mate with a common bull gear. Adjusting the HDI causes one pinion to preload the bull gear against the other pinion. At set-up, the assembler finds the loosest mesh point of the system and adjusts-out the backlash at that point. Any other
Drive Mechanism– Although all the presses are based on Slider Crank Mechanism, the crank can be of 3 types- Eccentric Gear, Crank Shaft, and Eccentric Shaft. Further, instead of using simple crank dive, link drive mechanisms can be used such as Knuckle Joint and 6-link Mechanism.

W. Brian Rowe DSc, FIMechE, in Hydrostatic, Aerostatic and Hybrid Bearing Design, 2012. Inter-Recess Flow and Bridge Angle. For an eccentric shaft, each recess pressure is different, as illustrated in Figure 1.3.Differences in recess pressures cause circumferential flow from one recess to another. Circumferential flow reduces bearing load support and also reduces film stiffness, particularly ...
The eccentric rotor oil pump is compact and simple and it is possible to drive several sets of rotors off the same shaft. In some specialist oil pumps for racing cars the pressure pump has five sets of rotors. ... Overhead camshaft engines employ a different drive system, which normally consists of a shaft driven by the crankshaft gears or chain.

RE: Torque to drive an eccentric mass rmw (Mechanical) 23 Feb 07 23:38 My senior lab project was similar to this and it had to be solved on an analog computer back in the day (shortly after we got electricity).
It is proved that the double eccentric instead of two degrees of freedom drive is feasible. The synchronization of system is effectively solved. It provided theoretical support for selection for ...
Eccentric weight 46, depicted as being pie-shaped, is fixed to shaft portion 24 and lies within a housing 48 which also encloses bearing 44. Housing 48 and eccentric weight may be referred to as drive box 50. Housing 48 includes an upper roof 52.
I got the eccentric motor replaced at an indie shop, they said the shaft is ok via manual adjusting. After the repair, there is no rapid clicking noise now. The relearn process is fine at that time and drives fine for two weeks. Then, the CEL is on and go to limbo mode some times. Code: 002DCE Valvetronic system: no adjustment possible.
kinematics of the drive´s mechanical system. This increase the service life of the tools used in warm forging and precision forging. Long parts can be produced in high volume in the automatic operating mode since the motion characteristics leave sufficient time for reliable part transport. Eccentric drive system of the MME press series.

A cycloidal drive or cycloidal speed reducer is a mechanism for reducing the speed of an input shaft by a certain ratio.Cycloidal speed reducers are capable of relatively high ratios in compact sizes with very low backlash.. The input shaft drives an eccentric bearing that in turn drives the cycloidal disc in an eccentric, cycloidal motion. The perimeter of this disc is geared to a stationary ...
