Bearing Definition and 186 Threads

I have a question regarding the bearing loads on a set of rotating shaft systems. The two systems are belt driven, each with one driver and one driven pulley. Belt tension is higher in system one than in system two. Rotational speed is higher in system two than in system one. The pulley...

Do the balls in a bearing actually touch both races? If so, how does the thing turn? Won't the balls be moving in different directions at each race, and therefore dragging against one?

1. Homework Statement You are given twelve cans (one of which is empty) which are filled with a certain number of ball bearings. Using nothing more than a balance, calculate the mass of a single bearing 2. Homework Equations Total Mass=Mo+n(mo) Where total mass=mass of ball bearings...

Universal joint/ball bearing... controlled rotating arm for a furniture fitting Hello forum, I need your help on a furniture project we are developing in the office. its basically a floor standing lamp which needs to have a user regulated rotating arm. We are right now looking at different...

I have a problem of bearing failure. A motor drives a shaft thro a flat belt. This shaft is connected to a load of around 40 kw. The shaft has 1309 self aligning ball bearing as floating bearing at the back end of shaft. On the load side there is a bearing 2209 NUP. The bearing inners are locked...

At work I have been given the task of finding force of ball bearing hitting a pick up finger in a ball nut. If you have no idea what that is then to simplify the scenario I am trying to model a ball bearing hitting a steel plate and the force that ball exerts on the plate. Back to physics...

i am in need of a brass ball bearing with a bore dia of 1/4inch. can anyone tell me where i could find it?

The question states: Ball bearing are made by letting spherical drops of molten metal fall inside a tall tower, and they solidify as they fall. a) If a bearing needs 4.0s to solidify, how high must the tower be? b) What is the bearing velocity when it reaches the bottom? c) What...

I am convinced I have not received enough info to solve this prob. Please help me get started. A small steel ball bearing with a mass of 20.0 g is on a short compressed spring. When aimed vertically and suddenly released, the spring sends the bearing to a height of 1.35 m. Calculated the...

Anyone can help me anayst the beariing which rest on the rod and was betweeen rod and ceiling...I am not sure if the reaction is between bearing and rod or ceiling and ball bearing. refer to this link pls

Homework Statement Ok, i have a small (optional) project, to design a load bearing structure made of matchsticks. The structure must be able to withstand the load a computer monitor (i have a 17" one). Homework Equations Now, the problem i am facing is how would the force (of gravity due to...

Dear all I need to calculate bearing Temperature for the shaft rotating of certain rpm. Bearing catalog referred and found that cooling factor is missing to arrive final result. How to find cooling factor?any empherical procedures?standards?sites? If so pl guide me to get the result...

Dear All, I have few questions:- Is styrofoam useful to bare heavy material weight? Is it light weight material? Waiting for reply. Thanks in advance.

Calculate the acceleration for a ball bearing between 25cm and 75cm of .4005 sec & .4013 sec and .4022 sec. Lab Help?! Thanks !

WE're usign a steel ball bearing for our physics rollercoaster project, and we happened to store the ball ontop of a decently strong magnet over the course of a few nights, and we believe that the ball is magnetized because the ball slows down at parts of our rollercoaster where there is any...

HI all, I am interested in designing a tapered bearing. Can anyone please let me know the parameters to be considered in order to design. I have been given a load acting on the sleeve, and the arae available to fit the bearing. If any useful site which talks about bearing and its...

Homework Statement M, a solid cylinder (M=2.07 kg, R=0.135 m) pivots on a thin, fixed, frictionless bearing. A string wrapped around the cylinder pulls downward with a force F which equals the weight of a 0.570 kg mass. Starting from rest, the mass now moves a distance 0.350 m in a time of...

Homework Statement A boat is moving with constact velocity -1 + 6j. Find the direction in which the boat is moving, giving your answer as a bearing. The Attempt at a Solution http://img483.imageshack.us/img483/2457/bearintgsxk3.jpg Alpha is the bearing I want right? In the mark...

I would like to calculate theoretically the capacitance of a bearing with metallic rings and ceramic spheres (see http://en.wikipedia.org/wiki/Rolling-element_bearing. The expression for a cylindrical capacitor is: (2*pi*eps0*l)/(lnb/a). However, when adding some spherical balls inside the...

Hi all, Ive made a car simulator for a uni project, i am now trying to calculate lateral acceleration (Gs) for the car. It models a car going round a track, however the track is made up of a series of straight lines, no curves. curve (type things) are achieved by a series of straight...

A ball bearing is held in a cup on the end of a pivoted rod. Weights can be added to the end of the rod opposite to that of the cup. The cup is pulled down and then released. The moving rod hits a stop and the ball bearing is projected out. When carrying out a pilot experiment, I found that...

Seek To Know About Tapered Roller Bearing Lubrication Used & Relubrication Period For The 1.5 Ton Three Wheeler's Front Wheel.

hey, well I am doing a project and the title is 'investigating how the distnce traveled by a ball bearing rolling down a slope affects time taken' so basically how the distance of travel (independent variable) effects the time taken to reach the end of the ramp. and, the ball starts from rest...

Can anyone think of any reasons why I should not be concerned about a seemingly large amount of end play in a bearing? The bearing is a twin taper roller bearing with a split inner race. It's carrying a mild, pretty steady axial load, and a moderate, pretty steady radial load, at a moderate...

Firstly I would like to point out I have absolutely no idea what I am doing and will most likely be blind or dead by tomorrow. But anyway. I've finally finished me first turbo jet engine (from scratch I would like to add and designed myself and dodgy as I am pretty convinced that it won't...

I've worked on this problem for over 5 years without success. A machine I am familiar with has a chronic bearing failure problem. Specifically, the cage disintegrates after about 6 months. The bearing is used in a vibratory application. An eccentrically weight shaft impels a total mass of about...

Dear Folks: The line in this article about testers being " simply unable to create enough friction in the lubricant to produce measurable damage - even when trial durations were increased severely beyond specifications", makes this sound as good as a magnetic bearing. Israel21c Erich

Alright, my teacher has the classic case of here are the sheets go do them, don't ask me questions. I've been good about picking up so far but i have 2 questions right now. 1) m/s^2 does this mean for every 2 seconds it does 1 meter value? I.E. 1/s^2 so does that mean every 2 seconds it goes...

Is there a way to relate the viscosity of a liquid to the fatigue wear of a bearing. The bearings are lubricated with the flow of liquid through the metering devise. The flow of liquid creates a perpendicular force on a shaft with carbon bearings on each end. Is there a formula that I can use...

A small steel ball bearing with a mass of 11.0 g is on a short compressed spring. When aimed vertically and suddenly released, the spring sends the bearing to a height of 1.37 m. Calculate the horizontal distance the ball would travel if the same spring were aimed 30.0 deg from the horizontal...

what is best,a machine we use in the food industry, cycles at 30rpm a direct drive cam opperates a lifter that travels 500mm up and down, the machine is washed down every night,there is no particulate matter. so would linear bearings or bushes be best for lifter? "lubrication is minimal"
