How to calculate allowable load for "buckling, tension, and compression" in ball screw axial direction

Today, we are going to discuss the "How to calculate allowable load for "buckling, tension, and compression" in ball screw axial directionHere is a note about "TheThere are two steps to using this statement.

1. Calculates the axial load applied to a ball screw when a heavy object is pushed around at an arbitrary acceleration. (SeeExplained in a separate article.）
2. Calculate how far the ball screw can withstand the load in buckling, tension, and compression.

will be.

Allowable axial load of ball screw

Ball Screws are Buckling occurs when axial compression exceeds the allowable limit. So,If a large load exceeding the allowable limit is applied, it may cause machine failure.

For that reason,Identify and select the diameter of the ball screw based on that load first.is the purpose of this statement.

In design, the diameter of the ball screw must be determined taking this allowable load into consideration.

this (something or someone close to the speaker (including the speaker), or ideas expressed by the speaker)The key point is that the allowable load in the axial direction varies depending on the mounting method of the ball screw.It is. I used this statement because

The unit is likely to be subjected to intense axial loads, such as

The allowable load in the axial direction can be calculated, but it may not be a problem unless the ball screw is clearly mismatched in size to the unit. Even if this is the case, it is still a good idea to check just to be sure. (Strength is a surprising concern.Strength of ball screw shaft terminal(It is)
