Embodiment Construction

[0025] see figure 1 with figure 2 , The present invention is a durable gear hydraulic coupling, which includes an inner sleeve 1, an outer sleeve 2, a flange sleeve 3, and an assembly and disassembly flange 4. The outer sleeve 2 is pressed against the outer circumference of the inner sleeve 1 and the inner circumference of the outer sleeve 2. The surface and the outer circumferential surface of the inner sleeve 1 are tapered. The inner hole of the inner sleeve 1 is an equal diameter hole. The outer circumference of the outer sleeve 2 is provided with external teeth. The external teeth are straight arc teeth 21 with a spherical tooth surface 22 and a spherical center. On the gear axis, and the tooth tops of the straight arc teeth 21 and the two tooth flanks are made into arc chamfers, the inner circumference of the flange sleeve 3 is provided with inner straight teeth 31, and the flange sleeve 3 is sleeved on the outer circumference of the outer sleeve 2. The inner straight tee...

Abstract

The invention provides a durable serrated hydraulic coupler. An inner sleeve, an outer sleeve, a flange casing pipe and a mounting and dismounting flange are all made of lead molybdate reinforced special steel. The lead molybdate reinforced special steel is prepared from, by weight percent, 0.041-0.043% of carbon, 2.42-2.58% of bismuth, 2.5-3.9% of lead molybdate, 0.3-0.4% of chromium, 0.1-0.2% ofcalcium, 0.05-0.06% of silver, 0.03-0.04% of magnesium arsenate, 0.02-0.03% of magnesium and 0.02-0.03% of scandium. The lead molybdate and the magnesium arsenate are added into original special steel, the hardness of the manufactured inner sleeve, outer sleeve, flange casing pipe and mounting and dismounting flange is greatly improved, and then the service life of the hydraulic coupler is prolonged.

Description

Technical field [0001] The present invention relates to the technical field of coupling structures, in particular to the field of hydraulic coupling structures for ships, in particular to a durable gear hydraulic coupling. Background technique [0002] The connection between the shaft and the shaft used in shipbuilding and other industries usually adopts flange or keyway connection. The connection method of this structure is expensive to manufacture, and the diameter of the connected shaft connection end needs to be increased, otherwise the shaft will be easily broken, so It is also difficult to use and install; in order to solve the above technical problems, straight-tooth hydraulic couplings have also appeared in the field to realize the connection between the shaft and the shaft, but the straight-tooth hydraulic couplings are used when the shaft is in use. When skewed or shifted, it is easy to cause jamming or even jamming of the tooth end, resulting in the coupling being scra...
