Process of Bolt Tightening and Tips to Improve the Same
Posted on: December 7, 2020
Bolt tightening is a complex process that must be carried out with complete efficiency. There are dedicated equipments which are available that can be used for bolt tightening. Such equipment helps in reducing the hassle concerned with tightening a bolt with complete skill and with minimum effort. Various factors affect the perfect tightening of a bolt which may include the type of equipment used, the angle of torque, and torque input. To ensure hassle-free torquing one must understand the complete process and engineering involved in carrying out the process.
The two main reasons which may affect the overall effectiveness of a bolt fastening is the lack of knowledge regarding the input load for bolt tightening torque as well as input angle. Improper levels of preload used for bolt tightening may also affect the overall effectiveness of torque. Moreover, bold tightening involves two completely different processes which include torque and turn. Understanding the various parameters and steps involved in fastening a bolt can ensure complete effectiveness and therefore help with the perfect functioning of a particular machine for longer periods. Bolt tightening through torque and involves the application of a sufficient amount of pressure through advancing and turning which can ultimately ensure hassle free and perfect bolt tightening.
The process involved in torque a bolt is listed below which can help in giving a clear picture of the steps involved regarding bolt fastening:
- Rundown – The equipment which is used for bold tightening is turned and the head touches the surface of the bearing which can ensure hassle-free movement without any problems. It is considered to be the most crucial process as the equipment for bold tightening must completely touch the below surface for efficient turning and movement.
- Perfect alignment – The next step involves perfect alignment between the fastener and the bearing surface to ensure complete contact for efficient movement. The alignment should be proper with the fastening equipment to making complete contact with the bearings office.
- Ensuring efficient clamping range – the slope of the torque angle curve must be constant to ensure maximum effectiveness of a bolt tightening. The clamping range should be kept constant with the application of the required amount of pressure.
- Post yields zone – To ensure perfect tension between the fastening equipment and bolt, a portion of the component yields.
The process mentioned above can be further improved by understanding the various aspects of bolt tightening like inspecting the surface material of bearing, fasteners as well as the environment of complete operation. Use of a perfect functioning bolt tightening machine which is perfectly calibrated and can help in the application of the required amount of pressure becomes necessary. One can even use dedicated analysis machines to ensure the equipment is perfectly calibrated and can be ultimately used for the perfect torque of a bolt. The use of the perfect mechanism for torque can ultimately help in the perfect functioning of the equipment with minimum errors. Periodic checks can be also carried out to ensure the torque for bolt tightening is efficient and sufficient for bolt tightening.
