Background technique
Propeller for vessels is one of the important component of ship power propulsion system.Its working condition directly influences ship
The operation cost of oceangoing ship.Under nominal situation, when blade rubs with water in water, blade surface can generate a small amount of bubble.Bubble exists
Rupture can generate cavitation corrosion to blade under subnormal ambient and frictional dissipation is inevitable.It is lost position and is primarily present in
Propeller guide margin, as a result, blade side is gradually thinning, blade effective active area is gradually reduced, and propeller self weight gradually subtracts
Gently, cause z-type propulsion unbalance, propulsive efficiency reduce, oil consumption increase, the speed of a ship or plane decline the problems such as.
Currently, repairing the thread indicator used for propeller in market of ship, since volume is big, transport is inconvenient, cost
It is high, and the range adjusted is small, and only manufacturer suitable for mass production uses, and the applicability of shiprepair is just not enough managed
Think.And the pitchometer of shiprepair at present is due to frequency of use is higher, service life is longer etc., it is larger that there are measurement errors
And volume and weight it is big rotation it is not flexible the disadvantages of.

On scroll chuck, the top of rotating device is arranged in the sliding block, and the slide bar is mounted on sliding block, and slide bar can be in sliding block
Upper sliding, the rangefinder include radial rangefinder and longitudinal rangefinder, and the radial direction rangefinder setting is described in slider top
One end of slide bar is arranged in longitudinal rangefinder.
As a kind of optimal technical scheme of the utility model, the rotating device include sleeve, connecting shaft, first bearing and
Second bearing, the connecting shaft are arranged on sleeve, and the first bearing is arranged in the junction of sleeve Yu connecting shaft bottom, and described the
The junction of sleeve Yu connecting shaft top is arranged in two bearings.
As a kind of optimal technical scheme of the utility model, the junction of the rotating device and sliding block adds equipped with triangle
Strong plate.
