Abstract
A kind of shell protection device of encoder, misplace sealing above and below being formed in the annular projection covered by the sealing gasket base wedge pressure on encoder shell, effectively protect dust, simultaneously sealing gasket is made using rubber or other elastomeric materials, it is set to produce deformation under the fastening pressure of encoder shell and gland, further protect dust and liquid, it is short with the process-cycle, cost is low, the advantage that production efficiency is high, product quality is stable, substantially increases uniformity and stability that encoder is used under adverse circumstances operating mode.
Description
Technical field:
The present invention relates to the guard technology of mechanical field, more particularly to encoder, the shell protection of particularly a kind of encoder is filled
Put.
Background technology
Existing encoder is in severe work condition environment in use, due to encoder degree of protection（IP40 after installation）Not enough, lead
Cause dirt, foreign matter or liquid to enter decoder internal, problems with can be caused：1st, there is foreign matter entrance, interfere sensing element,
Influence output accuracy；2nd, there are dirt entrance, influence circuit and code-disc precision；3rd, there is liquid entrance, encoder is damaged；Above situation
Cause encoder repair rate height, stability difference, it is necessary to spend substantial amounts of manpower and materials to safeguard, cost is high, less efficient, and production
Quality is unstable.
The content of the invention
It is an object of the invention to for drawbacks described above of the prior art there is provided one kind by encoder degree of protection improve to
The shell protection device of IP52 standards.
Its main operational principle be by the dislocation sealing above and below gland and encoder shell are formed in structure, with
And by sealing gasket be squeezed generation deformation formed interior sealing, effectively prevent external dust or liquid from entering decoder internal.
To achieve the above object, the present invention uses following technical scheme：The shell protection device of encoder, including gland,
Fastener, encoder shell, it is characterised in that the sealing gasket base of projection is provided with the encoder shell end face, it is described
It is provided with gland on the annular projection matched with the sealing gasket pedestal profiles, the sealing gasket base and elasticity is set
The sealing gasket that material makes, when the gland and the encoder shell are fastened with the fastener, the sealing gasket base meeting
Misplaced sealing above and below being formed in the embedded annular projection, and the sealing gasket is squeezed by the sealing gasket base and the gland bottom surface
Swaging is into sealing.
Further, the sealing gasket uses quality of rubber materials.
Further, be provided with the encoder shell end face on sealing gasket positioning convex, the gland be provided with
The groove that sealing gasket positioning convex matches.
The present invention compares with prior art, and its effect is actively and it will be evident that by encoder shell in the present invention
The annular projection that covers of sealing gasket base wedge pressure in formed above and below misplace sealing, dust is effectively protected, while using rubber
Or other elastomeric materials make sealing gasket, it is produced deformation under the fastening pressure of encoder shell and gland, further prevent
Dust and liquid are protected, short with the process-cycle, cost is low, the advantage that production efficiency is high, product quality is stable substantially increases volume
Code device is in the uniformity and stability used under adverse circumstances operating mode.

Fig. 1 is the structure chart of the present invention.
Fig. 2 is the side view of the present invention.
Fig. 3 is the encoder outer casing construction drawing in the present invention.
Fig. 4 is the gland structure figure in the present invention.
Fig. 5 is the gasket structure figure in the present invention.
Embodiment：
Embodiment:
As shown in Figure 1, Figure 2, shown in Fig. 3 and Fig. 4, a kind of shell protection device of encoder, including gland 1, fastener 3, encoder
Shell 4, it is characterised in that be provided with the sealing gasket base 41 of projection, the gland and set on the encoder shell end face 43
It is equipped with setting elastomeric material system on the annular projection 11 matched with the sealing gasket pedestal profiles, the sealing gasket base
When the sealing gasket 2 of work, the gland and the encoder shell are fastened with the fastener, the sealing gasket base can be embedded in institute
The sealing that misplaced above and below being formed in annular projection is stated, dust is effectively protected, the sealing gasket is by the sealing gasket base and the pressure
The extruding of base face 42 forms sealing, further protection dust and liquid.
Further, as shown in figure 5, the sealing gasket uses quality of rubber materials.
Further, as shown in Figure 3, Figure 4, sealing gasket positioning convex is provided with the encoder shell end face, can be
Prevent sealing gasket from shifting when assembling, reduction installation difficulty improves positioning accuracy and used and set on reliability, the gland
There is the groove matched with sealing gasket positioning convex.
