Abstract
The utility model belongs to an anti-rotation device with a radial moving rotating shaft bearing seat. The anti-rotation device comprises a box body (5) of a gearbox, a rotating shaft (1), a bearing (2), a bearing seat (3) and an elastic sealing ring (4). The anti-rotation device is characterized in that an anti-rotation pulling rod (7) is fixedly arranged on the bearing seat (3), and the other end of the anti-rotation pulling rod (7) is connected with the box body (5) through a guide groove (6). The anti-rotation device has the advantages that the anti-rotation pulling rod is limited through the guide groove and is only allowed to upwards and downwards move, the leftward and rightward movement is forbidden, and the damage to a sealing body when the bearing seat rotates along with the rotating shaft is effectively prevented.
Description
Technical field
The utility model belongs to a kind of parts of machinery, and particularly a kind of have an anti-rotation device that moves radially the rotating shaft bearing seat.
Background technique
In the mechanical seal device when running shaft has radial motion, because running shaft is flexible (the non-rigid connection) with seal between the gearbox casing, although seal is to link to each other with running shaft by bearing, but during the axle rotation, always there is certain rotating force to act on the seal, and the intensity of seal is not very high, being subjected to rotating force to do the time spent damages easily, especially when entering foreign material in the swivel bearing or damaging, the rotating force of running shaft directly can destroy seal, makes it lose seal action.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical deficiency, provide a kind of can limit the anti-rotation driving lever only permitted to move up and down, can not move left and right have an anti-rotation device that moves radially the rotating shaft bearing seat.
The technological scheme that the utility model technical solution problem adopts is: a kind of have an anti-rotation device that moves radially the rotating shaft bearing seat, the casing, running shaft, bearing, bearing support and the elastic seal ring that comprise speed change, it is characterized in that fixing an anti-rotation driving lever at bearing support, the other end of anti-rotation driving lever is connected with casing by guiding groove.
The beneficial effects of the utility model are: this model utility has limited the anti-rotation driving lever by guiding groove, is only permitted to move up and down, mustn't move left and right, prevented that effectively bearing support from rotating together with running shaft and injure seal.
Description of drawings
Below in conjunction with accompanying drawing, specify with embodiment.
Figure is the plan view with the anti-rotation device that moves radially running shaft.
Among the figure: the 1-running shaft; The 2-bearing; The 3-bearing support; The 4-elastic seal ring; The 5-casing; The 6-guiding groove; 7-anti-rotation driving lever.
Embodiment
Embodiment, with reference to the accompanying drawings, a kind of have an anti-rotation device that moves radially the rotating shaft bearing seat, comprise gearbox casing 5, running shaft 1, bearing 2, bearing support 3 and elastic seal ring 4, it is characterized in that fixing an anti-rotation driving lever 7 at bearing support 3, the other end of anti-rotation driving lever 7 is connected with casing 5 by guiding groove 6, and guiding groove 6 is located on the casing 5.
Working principle: when running shaft 1 rotation, rotating force is directly delivered on the bearing support 3 by bearing 2, is to flexibly connect by elastic seal ring 4 between bearing support 3 and the casing 5; Anti-rotation driving lever 7 one ends are fixed on the bearing support 3, the other end is connected with casing 5 by guiding groove 6, guiding groove 6 has limited 7 of anti-rotation driving levers and has been permitted to move up and down, can not move left and right, so just prevented that effectively bearing support 3 from rotating together with running shaft 1 and injure elastic seal ring 4.
Claims (1)
1. one kind has the anti-rotation device that moves radially the rotating shaft bearing seat, the casing (5), running shaft (1), bearing (2), bearing support (3) and the elastic seal ring (4) that comprise speed change, it is characterized in that fixing an anti-rotation driving lever (7) at bearing support (3), the other end of anti-rotation driving lever (7) is connected with casing (5) by guiding groove (6).
