subject: An Innovative, Three-piece Nut For Industrial Bolting That Waited 300 Years [print this page] Why would anyone consider replacing the nut at the end of the bolt with the nut of the three parts? Katsal standard threaded today originated in the 1700s, and should not be 300 years long enough to expect something new? Nuts of three parts is worth considering, because it ensures a reliable connection, do not get stuck and more secure than the rule.
First, a description of the standard, nuts of three parts:
- The industry standard nut is a mass of metal hexagon with a hole in the middle of strings. Hexagonal wrench is and the companions of the holes with the threaded bolt. Cat with the power of twisting spin nut along the bolt and bolt extends to provide a clamping load.
- It consists of three pieces of walnut three cylindrical parts: sleeves, washing machine, and the internal sleeve. I ferrule to the cylinder, and rotating outer sleeve with the power of torque, and walnut and extends three parts, and provides a clamp load bolt. All movements are relative within the nut. Nut does not turn into three parts along the screw.
Must be the goal of any bolt be quickly and safely producing a reliable connection bolting. Take a look at the problems caused by the walnut industry standard, and how to solve an alternative to the three parts.
Solve the problem # 1 - Bolt failure due to incorrect bolt loads
Standard fail pulled by the force of friction is known to cause over or under tightening. The main problem with the help of torque to tighten the nut is the contrast level of pregnancy caused by pregnancy tightening torque application. The forces of friction between the nut and bolt mounting surfaces have a large impact on the clamp load produced by the power of torque. This is because the nut three-piece has no relative movement between the internal cylinder and bolt, and washer and the surface mounting, and this voltage is not relevant. These are the movement in all three parts, with tightly controlled friction.
Solve the problem of 2 - problems moving because of an injury more than
It is always difficult to decode standard nut than it was to screw because of the damage and corrosion of the wire increases the friction between the mating threads and surfaces on the rise. With the Assembly of three parts, all the relative movements that take place inside the nut. Bolt thread and increase the friction surface of the mounting is not relevant to the kidnapping. Design considerations, selection of materials and lubricants in the security nut three parts that are controlled in the withdrawal of friction.
Solve the problem # 3 - Elimination of risks pinch points on the reaction
People get nuts while tightening the standard. Equipment which is used to screw and nut industry standard nose requires a torque arm to hold the tool in place during the process. This should also arm the reaction on a hard surface, it offers an ideal opportunity to pinch your fingers when you use. Units of three-piece arm eliminates the need for a reaction from within the surface reacts against the escalation of the elimination of pinch points.
And outdated for a long time nut standard for industrial applications. Three hundred years is long enough to wait for a new design nut. Three-piece walnut solves most of the problems caused by the standard nut and should be considered for all industrial applications bolting.
