uxcell Shaft Coupler D15 L24 Flexible Coupling Motor Encoder Inner Dia. 6mm to 8mm

Model: a17110100ux0260   |    Mpn: a17110100ux0260   |    PartNumber: a17110100ux0260   |   Asin: B078VTS3W9

Flexible couplings are used to link 2 rotating shafts that are not aligned in order to transmit the rotational power, known as torque, from 1 shaft to the other. Most flexible couplings consist of 2 hubs and 1 middle assembly; each hub attaches to a shaft while the middle assembly flexes between the hubs to accommodate the misalignment of the 2 shafts. Shaft misalignment are generally either parallel or angular and cause complications to transmitting rotational power from 1 shaft to another in the form of stresses, loads, vibrations, and other forces, which vary from 1 type of misalignment to another. Specification: Length: 24cm Outside Diameter: 15mm Bore Diameter: 6mm to 8mm Torque Range: 0.5N.m to 1.2N.m Material: Aluminium Alloy and TPU Feature: Designed for encoder; High flexibility, not easy to break; Simple structure, installation is convenient; Bushings are made of high-strength aluminum alloy; Elastomer is made of TPU, anti-oil and anti-oxidation; Package: 1 x Plastic Coupling

Features

  • 15mm Diameter X 24mm Length
  • Clamp-style mount for secure attachment to shaft
  • Accommodates angular, axial and parallel misalignment
  • Aluminum hubs for light weight, TPU elastomer for flexibility
  • Shaft couplers are applied for connect servo motor, stepper motor, encoder, machine platform etc.

Ruland PCMR29-12-6-A Clamping Beam Coupling, Polished Aluminum, Metric, 12mm Bore A Diameter, 6mm Bore B Diameter, 28.6mm OD, 38.1mm Length, 3.84 Nm Nominal Torque

 Ean: 0634529031933   |    PartNumber: PCMR29-12-6-A   |   Asin: B0060M69LQ

This Ruland polished aluminum clamping four beam coupling is intended for use in angular, parallel, and axial misalignment scenarios requiring zero backlash and less weight and quicker response time than a stainless steel coupler has. Beam couplings, a type of flexible coupling, use one or more spiral slots cut in a single piece of metal rod to form a "spring" center section, referred to as a helical coil or beam. The beam portions of the coupling flex to accommodate misalignment while continuing to convey power between the attached shafts. With four beams, each flex point corrects for a specific misalignment, which helps prevent stress on shaft bearings. This beam coupling corrects angular misalignment up to 3 degrees, parallel misalignment up to 0.38 mm, and axial motion up to 0.25 mm. This beam coupling's clamp-style mount can be installed or replaced without moving the shafts, which eases installation. Its single-piece construction provides longer service life than couplings with moving parts. The polished aluminum coupling is resistant to corrosion and can operate in temperatures ranging from -40 to 225 degrees F. This Ruland clamping four beam coupling is suitable for use in light duty applications such as coupling a servo motor to a lead screw in a motion control system.

Flexible couplings are used to link two rotating shafts that are not aligned in order to transmit the rotational power, known as torque, from one shaft to the other. Most flexible couplings consist of two hubs and a middle assembly; each hub attaches to a shaft while the middle assembly flexes between the hubs to accommodate the misalignment of the two shafts. Shaft misalignments are generally either parallel or angular and cause complications to transmitting rotational power from one shaft to another in the form of stresses, loads, vibrations, and other forces, which vary from one type of misalignment to another. Flexible couplings are used in a broad range of applications, such as in motor vehicles, conveyors, escalators, agricultural, forestry and mining equipment, aeronautics, robotics and space exploration, among others.

Ruland manufactures shaft collars, rigid couplings, and zero-backlash motion control couplings. The company, founded in 1937 and headquartered in Marlborough, MA, complies with Restriction of Hazardous Substances (RoHS) and Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) standards.

Features

  • Four beam coupling for use in angular, parallel, and axial misalignment scenarios requiring zero backlash
  • Polished aluminum for less weight and quicker response time than stainless steel
  • Clamp mounting style installation helps increase positioning accuracy
  • Single-piece coupling for longer service life than couplings with moving parts
  • Operating temperatures range from -40 to 225 degrees F
