Definitions

  • the present invention is related to transmission system developed for elevator drive machines with gear and having pipe-type shaft (4). Thanks to the fact that the shaft (4) is produced as pipe-type and hollow in the transmission system developed, resistance is increased against the static and dynamic loads occurring on the shaft (4). Moreover, the production, mounting and maintenance costs and periods of the motion transfer members used are decreased thanks to the transmission system having pipe-type shaft (4) developed. In addition, the weight of drive mechanism is also reduced remarkably thanks to the decrease in the amount of raw material used.
  • drive mechanisms with gear system are preferred in the present elevator systems.
  • the rotating motion obtained from the motor in elevator drive machines with gear used is transmitted to the transmission gear by means of shaft provided at the center of motor.
  • the rotating motion is transmitted to the pulley to which steel ropes are attached, by means of shaft passing through the center of transmission gear and rotating in an integrated manner with the gear. Therefore, up and down motion of the elevator cab and counter weights is achieved thanks to the rotating motion obtained from the motor.
  • the rotating motion obtained from the motor in the present elevator drive machines with gear by means of motor shaft is transmitted to the transmission gear by means of worm gear provided on the motor shaft and transmission gear and contact point.
  • Said rotating motion is transmitted to the shaft passing through the center of transmission gear and positioned vertically to the motor shaft.
  • the shaft transmits the rotating motion to the pulley, to which said shaft is attached through the center thereof, and the pulley is rotated by means of motor drive.
  • Static and dynamic loads occur on the shaft that transmits the drive received from motor to pulley and is in the form of filled shaft. Static loads are formed by cab attached to the pulley, to which the shaft is mounted through the end by means of steel ropes, cab internal load and counter weights.
  • Dynamic loads arise from the buckling momentum formed by the drive which is received from the motor shaft and transmitted to the shaft by means of transmission gear, on the shaft.
  • Said static and dynamic loads have certain upper limits in accordance with the shaft structure.
  • the upper limits of said static and dynamic loads cannot be increased to higher levels due to the material weights and sizes of shafts used in the present elevator machines with gear.
  • the shaft sizes that will be required for higher level of static and dynamic load resistance lead to excessive production costs and increase the size of elevator drive mechanism up to in applicable levels. Therefore, low static and dynamic load resistances can be achieved by means of shafts used in the transmission systems of transmission systems of present elevator machines with gear.
  • a gear hub made of cast material is mounted to the center of transmission gear made of bronze material. Said gear hub provides the integration and centering of transmission gear with shaft.
  • the production and mounting processes of bronze gear and cast gear hub both increase the production costs and extend the production periods.
  • the transmission gears used in the state of art receive drive from the center and thus, force occurs from center towards outside in accordance with high buckling momentum on the transmission gear and gear is broken.
  • the shaft (4) in the transmission system of elevator drive machine with gear developed is produced as hollow pipe-type. Therefore, static and dynamic load resistance forming force on the shaft (4) is increased.
  • the transmission gear (5) developed in the transmission system of elevator drive machine with gear is connected with the shaft (4) through the edge surfaces and thus, the pressure that will occur on the transmission gear

Hence, less lubricant is used when compared to the lubricant used in the present elevator drive systems and all of the mechanical parts are lubricated in an effective manner. In addition, the users use the high-quality lubricants in an economical manner thanks to the fact that efficient lubrication is performed with low amount of lubricant, and the usage life of the equipment forming the mechanism is extended.
