while all machine tools are 'machines that help people to make things', not all factory machines are machine tools. today machine tools are typically powered other than by human muscle e.g., electrically, hydraulically, or via line shaft , used to make manufactured parts components in various ways that include cutting or certain other kinds of deformation.
drive shafts are another common method used to move mechanical power around that is sometimes evaluated in comparison to chain drive; in particular belt drive vs chain drive vs shaft drive is a key design decision for most motorcycles. drive shafts tend to be tougher and more reliable than chain drive, but the bevel gears have far more friction than a chain.
the rotor is a cylindrical core made of steel lamination with slots to hold the wires for its 3-phase windings which are evenly spaced at 120 electrical degrees apart and connected in a 'y' configuration. the rotor winding terminals are brought out and attached to the three slips rings with brushes, on the shaft of the rotor.
a hydraulic drive system is a quasi-hydrostatic drive or transmission system that uses pressurized hydraulic fluid to power hydraulic machinery.the term hydrostatic refers to the transfer of energy from pressure differences, not from the kinetic energy of the flow.. a hydraulic drive system consists of three parts: the generator e.g. a hydraulic pump , driven by an electric motor or a .
the jopp group is an owner-managed group which is operating worldwide. its headquarters are located in bad neustadt a. d. saale in the northernmost bavarian administrative district. primarily, jopp is an automotive supplier, but also supplies components to other industrial sectors.
drive shafts tend to be tougher and more reliable than chain drive, but the bevel gears have far more friction than a chain. for this reason virtually all high-performance motorcycles use chain drive, with shaft-driven arrangements generally used for non-sporting machines. toothed-belt drives are used for some non-sporting models.
a direct drive mechanism is one that uses the torque coming from a motor without any reductions such as a gearbox .. direct drive mechanisms can be categorized in groups a torque motor mechanisms. output shaft is driven either by brush torque motor or brushless torque motor. the brushless torque motor requires commutation.
a clutch is a mechanical device which engages and disengages power transmission especially from driving shaft to driven shaft. in the simplest application, clutches connect and disconnect two rotating shafts drive shafts or line shafts . in these devices, one shaft is typically attached to an engine or other power unit the driving member .
the material used for ordinary shafts is mild steel. when high strength is required, an alloy steel such as nickel, nickel-chromium or chromium-vanadium steel is used. shafts are generally formed by hot rolling and finished to size by cold ding or turning and grinding. standard sizes. source: machine shafts. up to 25 mm steps of 0.5 mm
in mechanical engineering, a key is a machine element used to connect a rotating machine element to a shaft.the key prevents relative rotation between the two parts and may enable torque transmission. for a key to function, the shaft and rotating machine element must have a keyway and a keyseat, which is a slot and pocket in which the key fits.the whole system is called a keyed joint.
apex tool group is an american supplier of hand tools and power tools. it was formed as a joint venture of cooper industries and danaher by the merger of cooper tools and danaher's tools and components segment. in october 2012 danaher and cooper sold apex to bain capital for about $1.6 billion.
unit drive, which means using a single electric motor for powering a single machine, eliminated line shafts previously used to transmit power from a small number of steam engines or hydraulic turbines. line shafts created constraints on building arrangement that impeded the efficient flow of materials because they presented traffic barriers and .
steam turbines provide direct rotational force and therefore do not require a linkage mechanism to convert reciprocating to rotary motion. thus, they produce smoother rotational forces on the output shaft. this contributes to a lower maintenance requirement and less wear on the machinery they power than a comparable reciprocating engine.
an electric motor is an electrical machine that converts electrical energy into mechanical energy.most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of rotation of a shaft. electric motors can be powered by direct current dc sources, such as from batteries, motor vehicles or rectifiers .
