Description
[technical field]
The utility model relates to a kind of balancing machine of controlling by hydraulic efficiency gear.
[background technology]
Screw propeller is the representative type large rotating machinery, also is the power that boats and ships advance.But the problem of the maximum that large-scale marine propeller faces is a vibration problem, damages the performance of machinery owing to vibration and occupies sizable ratio.In vibrative a variety of causes, most importantly owing to screw propeller has force of inertia or the moment of inertia that unbalance mass, produces.According to statistics, the vibration of large-scale marine propeller, having more than 30% is because argosy is caused with unbalanced propeller.Therefore, the unbalance mass, of screw propeller must be controlled in allowed limits, otherwise the centrifugal inertial force that it produced is a value that can not be ignored.If the in esse unbalance mass, of screw propeller has exceeded to a certain degree, when its effect and the factors such as natural mode shape of the unbalanced and deflection of shaft of the hydrodynamism of propeller blade, axle when stack takes place, can aggravate above-mentioned harm undoubtedly, therefore, must be controlled the unbalance mass, of rotation, how improve argosy and seem particularly important with the quality that propeller balance detects.For small propeller, can ensure the quality of products evenly by casting accuracy and processing technology usually; And for large-scale spiral oar (quality is between 5 tons-100 tons), technological measure is difficult to guarantee its gravitational equilibrium precision must adopt other method to carry out the artificial compensation, and present common employing static balance method of testing detects the eccentric mass of screw propeller and compensates.
[summary of the invention]
The utility model is intended to overcome the defective that horizontal static balance method exists, and provides a kind of and can accurate detect the suspension type static balancing machine of argosy with propeller balance exactly.
Described large-scale marine propeller suspension type static balancing machine, it comprises support and the support mandrel that links to each other successively from bottom to top; Described support mandrel top is provided with globe bearing, and support mandrel outside face is with one and hangs mandrel; The bottom that hangs mandrel is provided with checking system and supporting cylinder, hangs the mandrel outside face and is with two relative tapered sleeves, and the top that hangs mandrel is provided with bearing cap shim; Wherein the top center of globe bearing and edge are complementary with the bottom centre of bearing cap shim and the shape at edge respectively, when globe bearing and bearing cap shim closed contact, top center and edge at globe bearing forms central seal face and edge sealing surface respectively, and the zone between center and edge forms compensating groove; And be provided with the delivery channel that communicates with the top-side of globe bearing at the support mandrel with hanging between the mandrel, globe bearing inside also is provided with the input channel that communicates with compensating groove; Wherein, described checking system, supporting cylinder and input, delivery channel link to each other with hydraulic efficiency pressure system respectively.
Wherein preferably, support is provided with the supporting base that is used for supported and suspended mandrel.
Further preferably, above-mentioned supporting cylinder is provided preferably with 8.And described checking system can be selected detection cylinder or precise displacement sensor for use.
The utility model is enclosed within the large-scale spiral oar and hangs on the mandrel with high concentricity, and by hydraulic locking apparatus and Large-sized Static Pressure Ball Bearing locking, Large-sized Static Pressure Ball Bearing, suspension mandrel and screw propeller integral body are under the effect of oil pressure, and the swing that is suspended in Large-sized Static Pressure Ball Bearing reflects.And everything is by HYDRAULIC CONTROL SYSTEM.Compare horizontal static balance method, the degree of automation height, friction moment is little, survey precision is high.In addition, adopt the unsteady adjective-centre structure of two-taper ferrule and the technology of second positioning, be effective measures to the centering error of eliminating center support system, thereby reduced its influence survey precision.

[specific embodiment]
The large-scale marine propeller suspension type of the utility model static balancing machine, it comprises support 1 and the support mandrel 3 that links to each other successively from bottom to top; Described support 1 is provided with the supporting base 2 that is used for supported and suspended mandrel; Described support mandrel 3 tops are provided with globe bearing 8, and support mandrel 3 outside faces are with one and hang mandrel 4; The bottom that hangs mandrel 4 is provided with checking system 5 and 8 supporting cylinders 6, hangs mandrel 4 outside faces and is with two relative tapered sleeves 7, and the top that hangs mandrel 4 is provided with bearing cap shim 9; Wherein the top center of globe bearing 8 and edge are complementary with the bottom centre of bearing cap shim 9 and the shape at edge respectively, when globe bearing 8 and bearing cap shim 9 closed contacts, top center and edge at globe bearing 8 forms central seal face 10 and edge sealing surface 11 respectively, and the zone between center and edge forms compensating groove 12; And be provided with the delivery channel 13 that communicates with the top-side of globe bearing 8 at support mandrel 3 with hanging between the mandrel 4, globe bearing 8 inside also are provided with the input channel 14 that communicates with compensating groove 12; Wherein, described checking system 5, supporting cylinder 6 and input, delivery channel 13 link to each other with hydraulic efficiency pressure system respectively.
During work, hydraulic oil is imported compensating grooves 12 by hydraulic efficiency pressure system by input channel 14, hydraulic oil is full of cell body, transmitting pressure raises the bearing carrier ring top from globe bearing 8, when being increased to globe bearing 8 edge sealing surfaces 11 when certain slit is arranged, hydraulic oil flows into delivery channel 13 by the slot leakage of edge sealing surface 11, compensating groove 12 decompressions, bearing carrier ring descends back behind the original position because of losing bearing pressure, counter balance pocket forms seal chamber once more, repeat above-mentioned cycle event again, formation bearing carrier ring liter → fall → liter → fall ... circulation float.
Before the work, open hydraulic efficiency pressure system earlier, make supporting cylinder 6 will hang mandrel 4 and boost, make globe bearing 8 be in released state with it, damage globe bearing in order to avoid when examined screw propeller 15 is installed, be subjected to direct impact.During work screw propeller 15 is sling, make the outer cone nature fit of propeller boss and tapered sleeve 7, screw propeller 15 and the theoretical axial line coincidence of hanging mandrel 4, by hydraulic efficiency pressure system supporting cylinder 6 is descended then, after hydraulic efficiency pressure system to input channel 14 fuel feeding, thereby bearing cap shim 9 rises to mention and hangs mandrel 4, detect the balance of himself by checking system 5, if screw propeller 15 overbalances, then hanging mandrel 4 and screw propeller 15 will overturn around the centre of sphere of globe bearing 8, can detect by precise displacement sensor.
