The design of barring gear: using in packet brake system, there is circular hole design in end face.2 pieces of high-strength bolt of installation.At the top of bolt Extension bar is welded, is more than original driving motor land lengths.Reinforcing transverse bar design is added between two extension bars.The weldering of extension bar end Connect jiggering bar." ten " word structure can be used in jiggering bar, and perpendicular end surface sets reinforcing rib design.When barring gear is installed, it is necessary to have bullet flat Mate-assist is padded, bolt, which installs every piece of screw rod, there are 2 pieces of fastening bolts.It prevents from generating loosening when jiggering.

The selection of barring gear material: determining according to friction coefficient, each transmission system etc. between beam weight and track, can be steady The torque of mobile input reduction gearbox system by torque capacity and combines the diameter of packet lock hole to determine the diameter and bolt of bar diameter Nominal diameter etc..Bolt selects 8.8 grades or more high-strength bolts in installation process, and nominal diameter must be less than normal straight in packet lock hole Diameter.Due to inputting motor installation kit brake system, the thickness of verification packet brake system hole wall when design meets starting and emergency stop power The demand of square, meets fatigue life requirements.When installation connects barring gear, packet brake system hole wall will not be torn when starting jiggering, Have an adverse effect.

The production and installation of barring gear: before barring gear production, it is necessary to measure good necessary dimensional structure.Driving motor installation Platform must have enough height for barring gear installation；Secondly measurement packet lock hole diameter；Finally measure driving motor platform Length.Remove driving motor Parallel Axis device system.Hole distance is measured, barring gear system is made.It is mounted directly connection bolt, tightly Gu barring gear bolt.
