How to calculate vibrating screen motor power?

Calculating the motor power of a vibrating screen involves several factors, including the type of screen, the amplitude and frequency of vibration, the size and shape of the screen deck, and the material being processed. Here is a general approach to calculate the motor power for a vibrating screen:

Determine the Screen Type

High Frequency Dehydration Vibrating Screen

Vibrating screens can be classified into horizontal, inclined, or banana screens. The type of screen will affect the calculation.

Identify Screen Parameters

Amplitude (A): The maximum displacement of the screen deck from its rest position.

Frequency (f): The number of oscillations or cycles per unit of time.

Calculate Vibrating Mass

Linear vibrating screen

The vibrating mass on the screen can be calculated using the formula:

m=Weight of the screen deck/g

where g is the acceleration due to gravity.

Calculate Excitation Force

The excitation force can be calculated using the formula:

F=m⋅A⋅(ω)²

where ω=2πf.

Determine Motor Power

The motor power (P) can be calculated using the formula:

P=F⋅v/ 1000

​where v is the vibrating speed (usually in m/s).

What are the universal matching requirements for angular contact ball bearings, and how to improve matching accuracy?

Currently, the commonly used matched bearings for machine tool spindles are angular contact ball bearings. Usually, complete sets of matched bearings are used. In some cases, non-complete sets of angular contact ball bearings may be used for universal matching. However, universal matching faces inconsistent accuracy. , inconsistent ruler time, inconsistent angle, etc., what are the universal matching requirements for angular contact ball bearings? And how to improve the matching accuracy? The following editor has compiled relevant content for you, hoping to be helpful to you.

What are the universal matching requirements for angular contact ball bearings?

PX Sealed 4 Point Contact Ball Bearing Series

When pairing angular contact ball bearings, in addition to relying on high-precision equipment during the production process to directly ensure the mutual differences in the inner and outer diameter groove dimensions, groove curvature, and groove position, the contact angle, the mutual difference in the inner and outer diameter dimensions, and the protrusion amount must also be ensured. Wait for the request.

1. Contact angle

The contact angle of universal matched angular contact ball bearings directly affects the stress state of the bearing under working conditions. The contact angle difference between two matched sets of bearings should be as small as possible. Generally, the contact angle difference between precision and ultra-precision matched bearings is About 1°. When selecting, the contact angle is controlled by controlling the radial clearance according to the relationship between the radial clearance and the contact angle.

cosβ= 1-Y/2 (Re+ Ri-2Rw)

In the formula:

β – contact angle

Y – radial clearance

Re – outer ring groove curvature radius

Ri – inner ring groove curvature radius

Rw – steel ball radius

As can be seen from the above formula, the difference in curvature radius of the inner and outer ring grooves can be effectively controlled during processing. Using the same set of steel balls for assembly can reduce the impact on the contact angle. Controlling the contact angle by fine-tuning the radial clearance can improve the angular contact Universal matching accuracy of ball bearings.

How does the harmonic reducer bearing work?

A harmonic reducer, also known as a strain wave gear or harmonic drive, is a type of precision gear mechanism used for speed reduction in various applications, particularly in robotics, aerospace, and industrial automation. The harmonic reducer bearing is known for its compact size, high torque density, and accuracy. It operates on the principle of elastic deformation to achieve gear reduction.Here’s an introduction to the main components and working principles of a harmonic reducer.

Components

harmonic reducer bearing

Wave Generator (Input Shaft): The wave generator is the input component that generates a wave-like motion, typically through an eccentric cam. This wave motion is transmitted to the flexspline.

Flexspline (Flexible Circular Spline): The flexspline is a thin, flexible, and toothed circular disc that deforms under the influence of the wave generator’s motion. It is the output element of the system.

Circular Spline (Fixed Outer Gear): The circular spline is a rigid, toothed ring that meshes with the flexspline. It is fixed in place and provides the necessary reaction to the flexspline’s deformation.

Working Principle

harmonic reducer bearing

Elastic Deformation: The key principle of a harmonic reducer is the elastic deformation of the flexspline. As the wave generator rotates, it creates a wave motion in the flexspline, causing it to deform. The deformation allows the teeth on the flexspline to engage with the teeth on the circular spline.

Zero-Backlash: One of the advantages of harmonic reducers is their minimal backlash. Backlash is the play or clearance between gear teeth. In a harmonic drive, the meshing of teeth is achieved through elastic deformation, reducing or eliminating backlash.

High Torque Density: Harmonic reducers are known for their high torque density, meaning they can provide significant torque output in a compact and lightweight design. This makes them suitable for applications where space and weight are critical factors.
