Abstract
The utility model is mainly used for a device for connecting a motor and a rotating mechanical part of a fan and a pressurizer, and in particular relates to a split pin. The split pin comprises two cylindrical metal pieces which are matched for use, and is characterized in that one end of one metal piece is provided with a threaded rod, while the other end is provided with an internal hexagonal groove; a tapered transition is formed between a cylindrical shape and the threaded rod; and one end of the other metal piece is provided with a tapered hole and a threaded hole, while the other end is provided with the internal hexagonal groove. The split pin can balance stress on a shaft in the frequent start-up and shutdown of the fan and the pressurizer, thereby prolonging the service life of the pin, reducing examination and repair frequency, prolonging production running period, lessening labor intensity and saving repairing cost.
Description
Technical field:
The utility model is mainly used in the motor of blower fan, press and the connection set of rotary machine part, is specifically related to a kind of split type pin.
Background technique:
At present, the most of steel Cylindrical object that adopts of the pin in the connection set (shaft joint, catcher) of the motor of blower fan, press and rotary machine part, overcoat buffering adhesive apron, the other end is fixed on the connection set (shaft joint, catcher) with screw thread and screw.Because there are frequent starting in blower fan, press etc. and stop, starting at every turn and stop the pin in the connection set (shaft joint, catcher) is produced shearing force, shearing force can make the pin fracture, the working life of influence pin.
Summary of the invention:
The utility model aims to provide long a kind of split type pin in working life.
The realization the technical solution of the utility model is: comprise two matching used cylindrical metal part, it is characterized in that an end of one of them metalwork is provided with threaded stem, the other end is provided with interior hexagonal indentations, tapered transition between the cylindrical and threaded stem; One end of another metalwork is provided with cone shape hole and tapped hole, and the other end is provided with interior hexagonal indentations.
The utility model can make axle at the frequent starting of blower fan, press with the stress balance in stopping, thereby has prolonged the working life of pin, has reduced the maintenance frequency, has prolonged the production run cycle, has alleviated labor intensity, has saved recondition expense.
