Description
Technical field
The utility model belongs to naval vessels and throws, rises the device that aft anchor is used, the hydraulic pressure aft anchor machine of particularly a kind of powder metallurgy system grinding disk clutch.
Background technique
At present, hydraulic pressure aft anchor machine is installed in the stern of naval vessels, for throwing, playing aft anchor usefulness, is the main hydraulic equipment on the naval vessels, and it is implemented the general anchoring function ships and light boats except having, and topmost function is that the landing craft after beaching is moved back Tan Xiashui; In order to guarantee that naval vessels can move back the beach safely, this equipment be divided into low in high third speed, low speed moves back when anchor is received on the beach and requires the aft anchor facility that 16 tons pulling force is arranged, the naval vessels that make water displacement reach 500 tons move back Tan Xiashui smoothly, along with moving back the beach, naval vessels speed up, for prevent anchor hawser with propeller cavitation, stern tube shaft, rudder blade, Shears strand around, require the aft anchor machine to receive anchor fast greater than 60 meters rope speed again, thereby the safety of guaranteeing naval vessels is moved back the beach with per minute.The structure of hydraulic pressure aft anchor machine mainly comprises oil hydraulic motor, main shaft device, braking device, rope guide, support, wherein main shaft device is by main shaft, bearing support, auxiliary cylinder, left and right hydraulic coupling, plane table thermoconductivity meter are formed, oil hydraulic motor is connected with main shaft by connecting spline housing, can directly drive auxiliary cylinder, can pass through plane table thermoconductivity meter transmission master rotor after left hydraulic coupling closes, make windlass be in bottom gear work, its speed ratio is 1: 3.54.Direct transmission master rotor after right hydraulic coupling closes, windlass is in top gear work.The winding of cable wire is synchronous on the master rotor, and cable wire can fitly be arranged on master rotor.Wherein the left and right hydraulic coupling in the main shaft device belongs to dry type, and its structure comprises: main shaft, fixedly spline housing, the gland of band wearing piece, two grinding disks, two braking plates, the hydraulic drive mechanism be made up of six small pistons, Returnning spring, pressure oil duct; In two grinding disks, one of them be single face be stained with wearing piece, by adopting the driving of six small pistons, make grinding disk and braking plate carry out clutch; Six small pistons transmit pressure by hydraulic oil in six cylinder bodies, compress braking plate and grinding disk after small piston stretches out, and make clutch; After the hydraulic oil release,, clutch is unclamped by the spring reset small piston.
The braking device of windlass is made up of brake strap and brake-fluid cylinder pressure.Brake strap is on the brake drum of cylinder.Pressure spring is housed in the oil cylinder, and the degree of tightness by connecting rod control brake strap, because the effect of spring force making brake be in the state of often stopping.When master rotor was worked, brake oil cylinder was under the effect of 1.5-16Mpa oil pressure, and pressure spring further is compressed brake is unclamped.Handwheel also is housed on brake oil cylinder, so as when emergent the manual control releasing of brake.It also has the water brake function, when spring breakage or stuck piston, pulls down the postive stop baffle on the console, implements water brake.Be mainly naval vessels and move back the beach and pulling force is provided and moves back take-up fast behind the beach, its auxiliary cylinder can be used for pulling hawser.The shortcoming and defect part of above-mentioned technology is described below:
(1) wherein the project organization of hydraulic coupling is not too reasonable, has only 4 attrition surfaces, and the friction torque ability of transmission is lower, the torque reserve coefficient is less, and when performance test, we can only accomplish 1.25 times load, when load increased again, the phenomenon of cltuch slipping will appear.
(2) wearing piece on its grinding disk is the adhesive bonding, be connected and fixed with rivet then, when connecting with rivet, must wait for that viscose glue just can carry out after fixing, general production time will be about 4～5 days, and when fixing rivet, because steel disc is the 45# steel, be easy to cause the grinding disk distortion, influence the horizontal angularity of card; Braking plate adopts spheroidal graphite cast iron, and the surface needs the card grinding, and precision and roughness are had relatively high expectations, and difficulty of processing is big, the processing cost height.

(4) the wearing piece material on this clutch grinding disk is an asbestos copper base, and is very high to the requirement of operating environment, on the make never allows to be stained with any oil stain, otherwise will cause cltuch slipping, scraps until wearing piece.
(5) spring brake is often malfunctioning, causes the aft anchor machine to work; As everyone knows, the brake weight of aft anchor machine derives from the pressure spring of brake oil cylinder.When the aft anchor machine was not worked, the pressure spring in the brake oil cylinder was pressed onto lower dead centre with piston, makes brake strap hold Brake drum tightly by brake linkage, was in braking state this moment.During the work of aft anchor machine, the brake oil cylinder cavity of resorption enters hydraulic oil, promotes piston stroking upward, and the pressure spring in the brake oil cylinder is compressed, and brake linkage makes brake strap take-off the brake wheel.If the impurity in the brake oil cylinder in the hydraulic oil is with stuck piston or pressure spring fracture, then spring tension can't promote descent of piston, thereby causes the aft anchor machine to lose brake function, and in use this phenomenon often takes place, both influenced work, acomia again at the scene eliminating.Must unload brake oil cylinder and deliver to REPSH repair shop or factory's place under repair this moment.And load and unload very difficult.
(6) hydraulic pressure aft anchor machine external leakage is serious; Be equipped with six brakings on every cover hydraulic coupling and divide piston cylinder, limit by the hydraulic coupling structure, divide piston cylinder to seal with traditional O RunddichtringO.But the O RunddichtringO is for pistons reciprocating, and sealing effect is not really desirable.
