Abstract
The utility model discloses a universal locator for A-bracket hubs of vessels, which comprises a locating shaft (1). Two groups of locating cones (2) in pairs are coaxially sleeved on the locating shaft (1), each two locating cones (2) in pair are arranged at intervals while small ends of the two locating cones (2) are opposite to each other, and a limiting sleeve (4) is disposed on the locating shaft (1) at positions of the outer side of the large end of each locating cone (2). Coaxiality of a front rubber bearing and a rear rubber bearing of a stern shaft mounted by means of the universal locator is greatly improved, favorable mounting efficiency is achieved during locating and mounting of shafts, mounting precision of the shafts are greatly improved, and vibration of the shafts can be reduced to a larger extent. In addition, power utilizing rate of a main unit is indirectly increased, service lives of the rubber bearings are prolonged, and comfortableness of vessels is improved.
Description
Technical field
The utility model relates to a kind of steady arm that is used for boats and ships Shears hub installing and locating.
Background technology
At present, be in location and installation process at the axle that is thrust power, the axle system medium and small-scale vessel that includes stern pipe, Shears (beauty's frame), stern tube shaft and screw propeller with the inboard machine, the installation of Shears (beauty's frame) hub is extremely important.If on the axial line (line of centers of stern pipe) of stern tube shaft, deviation is not bigger for the line of centers of the installation of Shears (beauty's frame) hub, will produce axle is that vibrations are big, causes the hull vibrations big, consumes the power of part main frame, shortens the life-span of rubber shaft bearing simultaneously.And the mounting means of present installation Shears (beauty's frame) hub all is with pulling shaft line (wire); With Shears (beauty's frame) hub sleeve on axis; The endoporus Zhou Yuan that measures rubber shaft bearing with interior card adjusts Shears (beauty's frame) hub from the distance of " wire ", and there are three kinds of following errors in this alignment adjusting method:
1, the axis that draws must guarantee at every moment all no changes, do not have and moves, but in real work, along with the weight change of hull and the influence of production environment on every side, also few variation more than the axis that draws all has;
2, the thickness of wire and pouring weight to be hung, the amount of deflection of wire, thereby the decentraction of generation axis;
The distance that the endoporus Zhou Yuan that measures rubber shaft bearing with interior card when 3, installing leaves " wire " has much relations with installer's level; Different people, the distance of measurement is different, generally speaking; All need technology well the master worker measure installation, but more than also few error arranged all.
The utility model content
It is a kind of simple in structure, easy to install that the purpose of the utility model is to provide, and installation effectiveness is high; Right alignment is high, can reduce the vibrations of axle system largely, improves the power utilization of main frame indirectly; Prolong the life-span of rubber shaft bearing, improve the general steady arm of boats and ships Shears hub of the comfort level of boats and ships.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: the general steady arm of boats and ships Shears hub, comprise fix shaft, and be arranged with the locating cone of two compositions on the fix shaft to being provided with; Fix shaft is coaxial with locating cone; Be provided with at interval between two locating cones that are provided with in pairs, that these two locating cones are little is relative, and fix shaft respectively is provided with a stop collar in a big outside of each locating cone.
Described fix shaft is provided with lining between locating cone and the stop collar therein.
Owing to adopted above-mentioned structure, through the stern tube shaft of installing with the utility model, right alignment of rubber shaft bearing is greatly improved before and after it; In the location and installation process of axle system, obtained good installation benefit, greatly improved the setting accuracy of axle system; Can reduce the vibrations of axle system largely; Improve the power utilization of main frame indirectly, prolong the life-span of rubber shaft bearing, improve the comfort level of boats and ships.And the utility model is in light weight, and processing is simple, and easy to use, commonality is good, has very strong practicality and promotional value.。
Description of drawings
Be described in further detail below in conjunction with the specific embodiment of accompanying drawing the utility model.
Fig. 1 is the cutaway view of the general steady arm of boats and ships Shears hub;
Fig. 2 is the block diagram that the general steady arm of boats and ships Shears hub is installed and used;
Fig. 3 is the cutaway view of Fig. 2.
The specific embodiment
As shown in Figure 1, the general steady arm of the described boats and ships Shears of the utility model hub comprises fix shaft 1, and fix shaft 1 is processed by stainless steel tube.Be arranged with the locating cone 2 of two compositions to being provided with on the described fix shaft 1, fix shaft 1 is coaxial with locating cone 2.Each is formed being provided with at interval between two locating cones 2 that are provided with, and this two locating cones 2 little relatively.Fix shaft 1 respectively is provided with a stop collar 4 in each locating cone 2 big outsides.Described fix shaft 1 is provided with lining 3 between locating cone 2 and the stop collar 4 therein.
As shown in Figures 2 and 3, when the utility model is installed and used: the first step in use: the rear end stop collar 4 of stern pipe rubber shaft bearing 7 is fixed on the appropriate location of fix shaft 1, puts locating cone 2; Second step: fix shaft 1 stretches into stern pipe 5 from stern pipe 5 rear ends; Be locked at stern pipe rubber shaft bearing 7 inner rings up to locating cone 2, and hold out against fix shaft 1, the locating cone 2 and the lining 3 of front end is inserted in fix shaft 1 by stern pipe 5 front ends; Compress lining 3; Be locked at stern pipe rubber shaft bearing 7 inner rings up to locating cone 2, put stop collar 4 again, compress and fix bolt; The 3rd step: the front end locating cone 2 and the stop collar 4 of the back rubber shaft bearing 8 of Shears hub 6 are inserted in, and the Shears hub 6 that will install back rubber shaft bearing 8 again is inserted in, and locating cone 2 and the stop collar 4 with the back is inserted at last, and the rear end of fix shaft 1 is supported reliably; The 4th step: after adjusting the front and back position of Shears hub 6; Front and back locating cone 2 is pressed in the rubber shaft bearing 8 of back together, and fixes corresponding stop collar bolt, so far; The position is just reserved in the upper and lower, left and right of the rubber shaft bearing in the Shears hub and front and back; The line of centers of the rubber shaft bearing on its line of centers and the stern pipe is consistent, has obtained the concentric effect of two bearings, afterwards the Shears hub is done corresponding the support and reserves the position; So, can the support arm of Shears be installed on the hull with regard to putting up with.
Through the stern tube shaft of installing with this " the general steady arm of Shears (beauty's frame) hub "; Right alignment of rubber shaft bearing is greatly improved before and after it; And (axle is processed with stainless steel tube) in light weight of this " steady arm "; Processing is simple, (point-and-shoot) easy to use, commonality good (the internal diameter replacing locating cone that only needs to press rubber shaft bearing gets final product).In the location and installation process of axle system, obtained good installation benefit, greatly improved the setting accuracy of axle system.
Should " general steady arm " be in the location and installation, so long as the diameter of axle (has comprised at present all axle systems) between 60-115 axle system all can install at real ship axle.
In a word; The above-mentioned preferred implementation though the utility model has been given an example; But should explain; Though those skilled in the art can carry out various variations and remodeling,, otherwise all should be included in the protection domain of the utility model only if such variation and remodeling have departed from the scope of the utility model.
