Hydraulic Dune Buggy Design: Is My Math Correct? - Physics Forums
2010年1月20日 · CG can be fine tuned since components can be placed anywhere. Not to mention making the buggy 4 wheel drive is near impossible without custom tranfer cases. This buggy could easily cost $15000 to build with 240hp, rear engine, and 4 wheel drive, maybe more. Heck high performance rear tranaxles can cost $10,000 alone.
Selecting hydraulic motors and a pump for hydrostatic transmission
2020年11月19日 · The max motor speed is 600 RPM = 10 rev/sec; So each motor will have a displacement of about 138 / 10 = 13.8 ml/rev. Now you can start to look for motors with a displacement of 13.8 ml/rev. (2.5 HP). You can look for a …
Hydraulic Pump/Motor: Can it Work as a Motor? - Physics Forums
2015年4月14日 · Hydraulic motors and pumps might get to 90% efficiency. A pump driving a motor will therefore have 90% * 90% = 81% efficiency. You will need to pay for that 19% inefficiency, you will also need an oil cooler to remove the 19% waste heat. A manual change gearbox will be closer to 98% efficient.
Calculating hydraulic motor sizes - Physics Forums
2011年10月18日 · The above calculation would be for the motor that is moving the log forward. There would actually be several hydraulic motors and cylinders as follows MOtors; 1.) To move log forward 2.) To run chainsaw 3.) To run a conveyor to remove wood once split Cylinders 1.) To split the wood 2.) Arm to hold the wood while being split 3.)
Flow in and out of hydraulic motor - Physics Forums
2022年12月29日 · A hydraulic motor is a mechanical device that converts hydraulic energy into mechanical energy. It uses pressurized fluid, usually oil, to create rotational motion and power machinery. 2. How does flow affect a hydraulic motor? The flow of fluid into and out of a hydraulic motor is crucial in determining its speed and torque.
Can Hydraulic Cylinders Be Driven by Refrigerants or Steam?
2011年11月23日 · A hydraulic cylinder works through the principle of Pascal's law, which states that pressure applied to a confined fluid is transmitted equally in all directions. When a force is applied to the piston in a hydraulic cylinder, it increases the pressure of the hydraulic fluid, causing the piston to move and generate linear force and motion. 3.
Torque Required To Move a Vehicle - Physics Forums
Oct 15, 2015. Torque Vehicle. In summary, John is trying to figure out how much torque is needed to move a 500-pound vehicle using two hydraulic motors. He estimates that the 40 ft-lbs of torque would be enough to move the vehicle. He also calculates that the vehicle should reach 10 mph within 4 seconds if the PSI required to keep the vehicle ...
Calculate hydraulic motor for a Flywheel - Physics Forums
2017年11月2日 · The hydraulic motor is not shown. The fly wheel has steel blades attached to a turning "steel cave". This structure is turning by an hydraulic motor and pulleys and belts. The hydraulic motor maximum speed is 750 rpm, torque is 19.5 Nm power is 12.5 W. My idea is to have pulleys that will turn the "Flywheel" at around 2.000 rpm.
What is the life (in cycles) for a hydraulic cylinder - Physics Forums
2011年5月20日 · Cycles Cylinder Hydraulic Hydraulic cylinder Life. In summary: The oil contains zinc for cylinder lubrication. We test it every 3 months for particulate and chemical contamination. Also for viscosity. If it fails for particulates, we filter it with a 3 µm filter. If it fails for anything else, we replace it with new and filter the new stuff ...
Geroler Motor Displacement Calc | Hobby Project - Physics Forums
2021年1月10日 · The displacement of a Geroler motor can be calculated by multiplying the number of lobes on the rotor by the width of the rotor and then dividing by the number of lobes on the stator. This formula can vary slightly depending on the specific design of the motor, so it is best to consult the manufacturer's specifications for an accurate ...
