Hot New Products TU-1A90 thermal wax actuator for automobile thermostat to Southampton Manufacturer Detail:

1. Operation Principle

The Thermostatic Wax that has been sealed in shell body induces expansion by a given temperature, and inner rubber seal part drives its handspike to move under expansion pressure to realize a transition from thermal energy into mechanical energy. The Thermostatic Wax brings an upward movement to its handspike, and automatic control of various function are realized by use of upward movement of handspike. The return of handspike is accomplished by negative load in a given returned temperature.

2. Characteristic

(1)Small body size, occupied limited space, and its size and structure may be designed in according to the location where needs to work.

(2)Temperature control is reliable and nicety

(3)No shaking and tranquilization in working condition.

(4)The element doesn’t need special maintenance.

(5)Working life is long.

3.Main Technical Parameters

(1)Handspike’s height may be confirmed by drawing and technical parameters

(2)Handspike movement is relatives to the temperature range of the element, and the effective distance range is from 1.5mm to 20 mm.

(3)Temperature control range of thermal wax actuator is between –20 ~ 230℃.

(4)Lag phenomenon is generally 1 ~ 2℃. Friction of each component part and lag of the component part temperature cause a lag phenomenon. Because there is a difference between up and down curve of traveling distance.

(5)Loading force of thermal wax actuator is difference, it depends on its’ shell size.

    Explains basic principles of stabilization of large manned spacecraft (including space stations such as Skylab – Apollo Telescope Mount and interplanetary spacecraft) and the use of control moment gyroscopes to maintain stability. The International Space Station (ISS) uses four CMGs.

    https://en.wikipedia.org/wiki/Control_moment_gyroscope

    A control momentum gyroscope (CMG) is an attitude control device generally used in spacecraft attitude control systems. A CMG consists of a spinning rotor and one or more motorized gimbals that tilt the rotor’s angular momentum. As the rotor tilts, the changing angular momentum causes a gyroscopic torque that rotates the spacecraft…

    Mechanics

    CMGs differ from reaction wheels. The latter applies torque simply by changing rotor spin speed, but the former tilts the rotor’s spin axis without necessarily changing its spin speed. CMGs are also far more power efficient. For a few hundred watts and about 100 kg of mass, large CMGs have produced thousands of newton meters of torque. A reaction wheel of similar capability would require megawatts of power.

    Design varieties
    Single-gimbal

    The most effective CMGs include only a single gimbal. When the gimbal of such a CMG rotates, the change in direction of the rotor’s angular momentum represents a torque that reacts onto the body to which the CMG is mounted, e.g. a spacecraft. Except for effects due to the motion of the spacecraft, this torque is due to a constraint, so it does no mechanical work (i.e., requires no energy). Single-gimbal CMGs exchange angular momentum in a way that requires very little power, with the result that they can apply very large torques for minimal electrical input.

    Dual-gimbal

    Such a CMG includes two gimbals per rotor. As an actuator it is more versatile than a single-gimbal CMG because it is capable of pointing the rotor’s momentum vector in any direction. However, the torque caused by one gimbal’s motion often must be reacted by the other gimbal on its way to the spacecraft, requiring more power for a given torque than a single-gimbal CMG. If the goal is simply to store momentum in a mass-efficient way, as in the case of the International Space Station, dual-gimbal CMGs are a good design choice. Instead, if a spacecraft requires large output torque per available input power, single-gimbal CMGs are a better choice.

    Variable-speed

    Most CMGs hold the rotor speed constant. Some academic research has focused on the possibility of spinning the rotor up and down as the CMG gimbals. These so-called variable-speed CMGs (VSCMGs) offer few practical advantages, mostly because the output torque from the rotor is likely orders of magnitude smaller than that caused by the gimbal motion. So, this effect adds nothing of practical value on the time scale of the motion typical of CMGs. However, thanks to the additional degree of freedom, the variable-speed CMG can be used to avoid the geometric singularity that is the most serious drawback of the conventional CMG. The VSCMG also can be used as a mechanical battery to store electric energy as kinetic energy of the flywheels.

    Singularities

    At least three single-axis CMGs are necessary for control of spacecraft attitude. However, no matter how many CMGs a spacecraft uses, gimbal motion can lead to relative orientations that produce no usable output torque along certain directions. These orientations are known as “singularities” and are related to the kinematics of robotic systems that encounter limits on the end-effector velocities due to certain joint alignments. Avoiding these singularities is naturally of great interest, and several techniques have been proposed. David Bailey and others have argued (in patents and in academic publications) that merely avoiding the “divide by zero” error that is associated with these singularities is sufficient. Two more recent patents summarize competing approaches…

    International Space Station

    The ISS employs a total of four CMGs as primary actuating devices during normal flight mode operation… CMGs absorb momentum in an attempt to maintain the space station at a desired attitude…



    In this video, engineer Jim Bostwick of the HaydonKerk division of AMETEK Precision Motion Control explains the basic motion and power-transmission functions of his company’s lead-screw driven actuator assemblies. Shot in Chicago at the last PackExpo, this video also shows some leadscrew closeups. As Bostwick explains, this lineup of HaydonKerk products from 1/8-in. diameters all the way to 15/16-in. diameters. Leads range from 0.012 of an inch to three inches per revolution.

    Some of the lead-screw offerings also integrate guide rails. Called the screw rail, these assemblies include both the rotary-to-linear subcomponent (in the form of the screw) and the linear rails to essentially handle radial, axial, and moment loads. In fact, some versions also include support frames for the screw … so engineers can get the design in versions up to eight feet long … without any worries about screw whip or vibration.

    In this video, Bostwick also explains how step motors and even drives can go onto HaydonKerk lead-screw designs. His company sells these predesigned and preassembled as fully integrated turnkey actuators.
