Is the oil suitable for ball screw lubrication?

The ball screw can be lubricated with grease or oil. Grease is more commonly used for ball screw lubrication because it does not require complicated delivery methods and does not require frequent relubrication intervals. However, despite the simplicity of using grease, oil lubrication is a better choice for ball screw assemblies in many applications. First, the oil provides cooling and minimizes heat accumulation in the ball screw assembly. Heat will cause the thermal expansion of the screw shaft, which will change the size of the thread and negatively affect the positioning accur

Some characterics of Ball Screw pair

Ball screw pair, also known as ball screw pair, ball screw pair. It is composed of two sets of screws and nuts. It is the most accurate and most commonly used transmission device in transmission machinery. Introduction Edit Broadcast When moving an object, it is generally necessary to transmit the motion generated by the power directly or indirectly through other mechanisms to the final moving part. Taking the engine as an example, in the engine, the piston moves up and down due to the combustion of gasoline, and finally transmits it to the wheel through the intermediate mechanis

The origin of the development of bearings

History development of bearing Bearings The early form of linear motion bearing is to place a row of wooden rods under a row of skids. Modern linear motion bearings use the same working principle, but sometimes use balls instead of rollers. The simplest rotary bearing is the bush bearing, which is just a bushing sandwiched between the wheel and the axle. This design was subsequently replaced by rolling bearings, which replaced the original bushing with many cylindrical rollers, each like a separate wheel. An early example of a ball bearing was found on an ancient Roman sh

Ball screw nut pair working principle

Ball screw nut pair is a commonly used transmission device for converting rotary motion into linear motion in CNC machine tools. It replaces the sliding in the screw nut pair with the rolling of the ball, with low friction and good performance. 1. Composition and working principle: ·Composition: It is mainly composed of screw rod, nut, ball and raceway (ball return device), nut seat, etc. ·Working principle: Arc spiral grooves are processed on the screw rod and nut.

Calculation of Ball Screw Thrust

Thrust in the drive direction of the screw background origin Why do this lead screw thrust calculator? First of all, because the current work requires frequent selection of the matching lead screw and motor, it is quite troublesome to calculate the thrust of the lead screw manually. A formula needs to be transformed over and over to calculate different variable values. In addition, the calculator scientific mode provided by WIN 10 has no pi value, which is very inconvenient to calculate, and the results cannot be saved and compared wi

which ball screw will have grinding cracks after intermediate frequency quenching

At present, medium frequency induction hardening is generally used for large screw rods. In production, it often happens that the hardened (tempered) screw rod is threaded and inspected by magnetic inspection. It is often found that the axial direction appears on the arc of the thread raceway. Cracks or net-like cracks can even be found with the naked eye during the thread grinding process, causing the screw rod to be scrapped. This not only caused direct economic losses to the enterprise, but also caused a lot of pressure on the production of the enterprise due to the various factors that cau

Installation method of ball screw steel ball

First of all, it is not recommended that users remove and install nuts by themselves, especially high-lead ball screws. Before installing the nut of the ball screw, you must have a sleeve (also called a dummy shaft) with the same diameter as the ball groove of the screw. After the nut is cleaned with liquid oil, apply grease to the ball groove to stick the balls one by one. Put it in the ball groove, put the sleeve into the nut after putting it, use the screw to hold the sleeve and rotate it to screw it in. The function of the sleeve is that the ball will not be squeezed out when the ball scre

How to prevent the ball screw from deforming after heat treatment

The characteristics of the ball screw are high processing accuracy and strict deformation requirements. Due to the many processing procedures, the heat treatment quality and deformation are very important. It was found in production that the workpiece was severely deformed after carburizing and quenching, and it was difficult to correct it. Large deformation also appeared in the processing after heat treatment, which caused a large number of product repairs and many workpieces to be scrapped. In order to ensure the performance of its mechanism and to facilitate th
