Abstract
The utility model discloses an alloy bearing extractor. The alloy bearing extractor is characterized in that the alloy bearing extractor comprises a screw rod, a supporting board, a supporting rod, a locating sleeve and a baffle device. A spinning nut is installed at the top of the screw rod. The supporting board is installed on the front half portion of the screw rod and provided with the supporting rod. The locating sleeve is installed in the middle of the screw rod. The baffle device is installed at the bottom of the screw rod. The baffle device further comprises a block, an extension spring and a spin-fixing nut. The baffle device is fixed to the screw rod through the spin-fixing nut. The center point of the block is fixed to the baffle device. The block can rotate around the center point. One end of the block is connected with the baffle device through the extension spring. The alloy bearing extractor is high in universality and suitable for detaching bearings of different standards after the sizes of a few parts are adjusted, the structure is simple, and operation is convenient.
Description
Technical field
The utility model relates to shipbuilding apparatus field, particularly a kind of alloy bearing extracting tool.
Background technology
In ship domain, when alloy bearing fatigue, the wearing and tearing of ship stern pipe, thereby cause the shape of brearing bore to produce distortion, such as out-of-roundness and tapering is overproof, movement clearance becomes large etc., distortion, by having a strong impact on the navigation quality of boats and ships, now needs to change stern tube bearing.The method of some boats and ships dismounting stern tube bearings in the past, in the situation that cabin space allows, adopts rod iron to be stretched in stern pipe and outwards knocked bearing by cabin, wastes time and energy, and labour intensity is large, and stern pipe position produces skew distortion, damages owing to striking shake.And for high-speed ship, ship stern pipe device is longer, some even can reach 4300mm, adopt conventional method cannot dismantle stern tube bearing at all.
Summary of the invention
It is a kind of simple in structure, easy to operate that the purpose of this utility model is to provide, and reduces labour intensity, the instrument that the alloy bearing to ship stern pipe of highly versatile is dismantled.
For achieving the above object, alloy bearing extracting tool of the present utility model, comprise bearing, it is characterized in that: it also comprises screw mandrel, gripper shoe, support bar, positioning sleeve and retaining device, described screw mandrel top is provided with spinning nut, and described gripper shoe is arranged on screw mandrel first half, and gripper shoe is provided with support bar, described positioning sleeve is arranged on screw mandrel middle part, and described screw mandrel bottom is provided with retaining device.
Retaining device also comprises block, extension spring and is rotated with nut, retaining device is by being rotated with nut and screw mandrel is fixed, the central point of described block is fixed on retaining device, and block can be around central point turn, and one end of block is connected with retaining device by extension spring.
Described support bar quantity is four, and support bar bottom has screw thread.
Described positioning sleeve and bearing are suitable.
Substantive distinguishing features of the present utility model and progress are:
The application's the extracting tool for ship stern pipe alloy bearing, longer according to ship stern pipe, the feature that conventional method cannot be dismantled bearing, design this extracting tool, screw mandrel utilizes spring to make block block bearing after putting in bearing, thereby bearing is drawn off, simple in structure, easy to operate, reduce labour intensity.The highly versatile of this extracting tool, can suitably adjust after the size of individual part the i.e. bearing removal applicable to different size according to the size of actual stern pipe and bearing.
Accompanying drawing explanation
Fig. 1 is that this alloy bearing extracting tool enters the schematic diagram in bearing process.
Fig. 2 is the schematic diagram that this alloy bearing extracting tool dismounting preparation completes.
Component serial number and title in figure:
Screw mandrel 1, spinning nut 2, gripper shoe 3, support bar 4, positioning sleeve 5, retaining device 6, block 7, extension spring 8, be rotated with nut 9, stern pipe 10, bearing 11.
The specific embodiment
Below in conjunction with accompanying drawing, enforcement structure of the present utility model is described.
Shown in Fig. 1 and Fig. 2, alloy bearing extracting tool of the present utility model, screw mandrel 1 top is provided with spinning nut 2, and gripper shoe 3 is arranged on screw mandrel 1 first half, and gripper shoe 3 is provided with support bar 4, and support bar 4 quantity are four, support bar 4 bottoms have screw thread.Positioning sleeve 5 is arranged on screw mandrel 1 middle part.Screw mandrel 1 bottom is provided with retaining device 6, retaining device 6 also comprises block 7, extension spring 8 and is rotated with nut 9, retaining device 6 is fixing with screw mandrel 1 by being rotated with nut 9, the central point of block 7 is fixed on retaining device 6, block 7 can be around central point turn, and one end of block 7 is connected with retaining device 6 by extension spring 8.
The operation principle of this alloy bearing extracting tool is described below in conjunction with accompanying drawing and the course of work:
Before dismounting alloy bearing 11, positioning sleeve 5 is penetrated to screw mandrel 1, with being rotated with the fastening retaining device 6 of nut 9, four support bars 4 are packed in gripper shoe 3.Screw mandrel 1 is stretched into bearing 11, see Fig. 1, until retaining device 6 is crossed bearing 11 bottoms, now open around central point turn by extension spring 8 pulling force block 7 one end, open backstop 7 other ends and block bearing 11 bottoms, see Fig. 2, then toward post-tensioning, block 7 and bearing 11 bottoms are fitted tightly screw mandrel 1.Utilize screw thread to screw in equably by root in the screwed hole of stern pipe 10 support bar 4, support bar 4 is carried out fastening, fix gripper shoe 3.
Finally screw in spinning nut 2, can start to carry out field-strip.Positioning sleeve 5 is suitable with bearing 11, interior to screw mandrel 1 effective location at bearing 11, avoids rocking of screw mandrel 1 in unloading process.When dismounting, turn screw mandrel 1, toward outside pull-out, utilizes the block 7 being connected with screw mandrel 1 to block bearing 11 bottoms, bearing 11 is pulled out, until bearing 11 is deviate from stern pipe 10.
