What is Skive hose?
Skiving refers to removing (or shaving) part of the hydraulic hose cover and/or inner tube prior to attaching hose ends. No-skive means the hose and fittings are designed to work without this step. The thicker cover requires a different hydraulic fitting shell due to the thickness.
How does a swivel fitting work?
Swivel-type fittings are designed to allow the coupling and hose connection to rotate, which prevents twisting, kinking and excessive bending. Because swivel joints move, they can compensate for hose length changes when the system pressurizes and absorb hydraulic surges and shocks in a line.
How do you measure a hydraulic hose?
In the vast majority of common hydraulic hoses, the I.D. measurement is divided into 1/16” increments known as the “dash size.” For example, a hose measuring 3/4” ID will be shown as a “-12” coming from the numerator of the fraction of 3/4″=12/16”. A 1” ID would be 16/16 or a -16, and so on.
Why do hydraulic hoses fail?
Hydraulic hose failure is most commonly caused by abrasion, poor routing, high temperatures, tube erosion, bent hoses near fittings, fluid incompatibility, and improper assembly. If high pressures are involved, there is also a potential risk of physical injury to employees when hoses burst.
What is the function of swivel?
A swivel is a connection that allows the connected object, such as a gun, chair, swivel caster, or an anchor rode to rotate horizontally or vertically.
What is a swivel connection?
Swivel fittings are rotating adapters and connectors that are often made available in metal for better durability and strength. Important benefits of using swivels include. Extending hose life. Eliminating kinks in supply lines. Reducing maintenance frequency and costs.
What size is hydraulic?
Simply put, a dash size refers to an I.D. of a hydraulic hose or fitting in 1/16″ increments. For example, -6 hose would indicate a hose with I.D. of 6/16″ – or 3/8″. Hoses are measured by inside diameter, unlike tubes which are measured by outside diameter.
What is the common defect in the hydraulic hose?
Hydraulic hose failure is most commonly caused by abrasion, poor routing, high temperatures, tube erosion, bent hoses near fittings, fluid incompatibility, and improper assembly. These failures are serious matters, no matter what industry or type of equipment is involved.
Can you over crimp a hydraulic hose?
You could crimp it from 1.027 to 1.043. Anywhere within that range, the hose is still valid, but you don’t know where you’re at. You either risk over-crimping and restricting flow or damaging the braiding on the hose, or you risk it not being crimped enough and blowing off a hose end.
What is a swivel?
A swivel is a device that allows something to turn freely. Swivel comes from a middle English word, swive, meaning to sweep. It’s often used to describe gun mountings, like on a tank or a boat where a gun is fastened down but can still be swung around in any direction.
What’s the meaning of Skive in the Dictionary?
: to avoid work or school by staying away or by leaving without permission … 71 per cent said rewards for good ideas and punctuality would make them work harder and not skive … — South Wales Evening Post Tam is 15 and he’s skiving school.
When to use s Flex or X flex shafts?
1 If your driver swing speed is approximately 110 mph or higher, and your carry distance around 270 yards, go with X flex shafts. 2 If your speed is 95 to 110 mph and your carry distance 240-270 yards, go with S flex. 3 If your speed is 85 to 95 mph and your carry distance is 200 to 240 yards, go with R flex.
What do you need to know about power skiving?
Power skiving is a continuous machining process where the tool meshes with the gear being made — similar to the way a pinion and gear mesh in a gear train. This is the reason that an extremely accurate synchronization is needed between the workpiece spindle and the tool spindle.
Which is the best wax for power skiving?
Even in capable machines, it is recommended to start with plastic or machinable wax. As seen, using a higher cross angle reduces the spindle speeds (up to 45 degrees). Since one of the biggest hurdles in power skiving is maintaining synchronization at high spindle speeds, a larger angle is therefore beneficial.
