Abstract
The utility model discloses a kind of suspended hydrogenerator thrust collar dismantling device.Be made up of screw rod, disk, bolt, packing ring and nut, be applicable to the suspended hydrogenerator of thrust collar and the tight amount of axle employing or matched in clearance.New tool make thrust collar in the process of dismounting uniform stressed, at the uniform velocity advance, can effectively prevent thrust collar and axle from grinding because of unbalance stress.This tool construction is simple, easy to operate, is the common tool of hydrogenerator suspension-type unit thrust collar dismounting, has very strong popularized type.
Description
Technical field:
The utility model relates to a kind of suspended hydrogenerator thrust collar dismantling device.
Background technology:
Suspended hydrogenerator thrust collar is arranged on the upper end of generator shaft, and the cooperation of thrust collar and axle is interference fit, and between by key connect come transmitting torque.The cooperation section of thrust collar and axle to join car tolerance strict, machining accuracy is higher, and in the installation and removal process of thrust collar, unbalance stress, bias can cause coordinating section to grind.The result of grinding causes thrust collar and shaft clearance is excessive, decentraction, and unit axis is difficult to adjustment, vibration when having influence on unit operation and throw.
Summary of the invention:
The purpose of this utility model structurally designs one to apply to suspended hydrogenerator thrust collar dismantling device, and the technical solution of the utility model is: suspended hydrogenerator thrust collar dismantling device, is made up of screw rod, disk, bolt, packing ring and nut.Disk is fixed on generator shaft top by bolt, packing ring.During dress thrust collar, screw rod withstands thrust collar through the screwed hole on disk, turns screw rod with spanner, relies on screw rod and the power transmission of disk screw thread that thrust collar is headed on movement, is in place by thrust collar.When tearing thrust collar open, screw rod is screwed into through the unthreaded hole on disk the screwed hole that thrust collar is arranged, and turns nut, relies on the screw thread power transmission of screw rod and nut that thrust collar is hauled movement, thrust collar is split out the section of cooperation with axle.
Technique effect:
The demolition, installation process of thrust collar is consuming time less than 2 hours (except the thrust collar heating time), and thrust collar uniform force, shows no sign of with axle and grind.This new tool can meet macro-axis at clipping room, can meet again macro-axis dismounting in machine hole.And in the process of dismounting, just used conventional Wrench, tool construction is simple, practical.
Accompanying drawing explanation
Fig. 1 is the utility model suspended hydrogenerator thrust collar dismantling device
Detailed description of the invention
A kind of suspended hydrogenerator thrust collar dismantling device as shown in Figure 1.Be made up of screw rod 1, disk 2, bolt 3, packing ring 4 and nut 5.Disk 2 is fixed on generator shaft top by bolt 3, packing ring 4.During dress thrust collar, screw rod 1 withstands thrust collar through the screwed hole on disk 2, turns screw rod 1 with spanner, relies on screw rod 1 and the power transmission of disk 2 screw thread that thrust collar is headed on movement, is in place by thrust collar.When tearing thrust collar open, screw rod 1 is screwed into through the unthreaded hole on disk 2 screwed hole that thrust collar is arranged, and turns nut 5, relies on screw rod 1 and the power transmission of nut 5 screw thread that thrust collar is hauled movement, thrust collar is split out the section of cooperation with axle.
