Description

Technical Field

[0001] The utility model relates to a coupling cover, and more specifically, to a coupling cover with axially fine-tunable dimensions. Background Art

[0002] For an ordinary coupling cover, angle iron is used as the frame and thin plates are wrapped outside. It is made according to the design drawings, and the axial dimension is fixed. However, when the coupling cover is installed between the pump and the motor and fixed on the common base, the axial installation dimension is often affected by the dimensions of the pump, the motor and the base. If the actual axial installation space dimension is too small, the coupling cover cannot be installed; on the contrary, if the dimension is too large, the gap between the end face of the coupling cover and the pump or the motor becomes larger. If it exceeds the safety permission range, the coupling cover cannot be used because the end face gap is too large. With the improvement of users' safety requirements, the probability of this problem occurring is increasing.

[0003] At the same time, the conventional coupling cover is made by bending flat thin plates into a U shape, and has poor rigidity. When an external force touches the coupling cover, the coupling deforms and moves, especially in the radial direction. Once the coupling cover touches the rotating surface of the coupling, it is unsafe. Therefore, sometimes it is necessary to increase the thickness of the plate or add angle iron to reinforce the end cover part of the coupling cover, which makes the production difficult and the cost high. Summary of the Utility Model

[0004] Aiming at the above defects existing in the prior art, the purpose of the utility model is to provide a coupling cover with axially fine-tunable dimensions, which improves the rigidity of the coupling cover and also improves the use safety of the pump unit.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A coupling cover with axially fine-tunable dimensions includes a coupling cover body, and the coupling cover body includes a front end cover, a rear end cover, an intermediate cover and fixed angle irons;

[0007] The front end cover is connected to one end of the intermediate cover;

[0008] The rear end cover is connected to the other end of the intermediate cover;

[0009] There are 2 fixed angle irons, which are respectively arranged at positions close to the lower ends of both sides of the front end cover, the intermediate cover and the rear end cover;

[0010] A plurality of waist-shaped long holes are opened on both the front end cover and the rear end cover;

[0011] The length direction axis of the waist-shaped long hole is arranged parallel to the length direction axis of the coupling cover body.

[0012] Preferably, the front end cover, the intermediate cover and the rear end cover are all arranged in an inverted U shape.

[0013] Preferably, the front end cover and the rear end cover are made of stamped parts or sheet metal welded together, and have the same shape and size.

[0014] Preferably, the cover plate of the middle cover is arranged in a corrugated shape.

[0015] Preferably, the front end cover, the middle cover and the rear end cover are connected by fixing screws for tapping threads.

[0016] Preferably, the fixing angle iron is arranged in an L shape.

[0017] The coupling cover with axially fine-tunable dimensions provided by the present utility model cancels the angle iron in the vertical direction on the existing end cover, so it can be formed by stamping, with high manufacturing precision, consistent shapes and sizes of the front and rear end covers, improving the standardization rate and facilitating cost reduction; the axial dimension of the coupling cover is adjustable through the waist-shaped long holes; the middle cover is corrugated, improving the rigidity of the coupling and saving materials; the use of fixing screws makes the connection reliable, and the disassembly, assembly and adjustment are convenient.

[0023] In order to better understand the above technical solutions of the present utility model, the technical solutions of the present utility model will be further described below with reference to the drawings and embodiments.

[0024] Combined with Figures 1 to 5 as shown, a coupling cover with axially fine-tunable dimensions provided by the present utility model includes a coupling cover body 100, and the coupling cover body 100 includes a front end cover 1, a rear end cover 2, a middle cover 3 and a fixing angle iron 4.

[0025] One end of the front end cover 1 and the middle cover 3 are fixedly connected by a fixing screw 5 for tapping threads.

[0026] The other end of the rear end cover 2 and the middle cover 3 is fixedly connected by fixing screws 5 for tapping threads.

[0027] There are 2 fixing angle irons 4, which are symmetrically installed and fixed on both sides of the front end cover 1, the middle cover 3, and the rear end cover 2 near the lower end through fixing screws respectively.

[0028] A plurality of oblong holes 6 are provided on both the front end cover 1 and the rear end cover 2.

[0029] The lengthwise axis of the oblong hole 6 is arranged parallel to the lengthwise axis of the coupling cover body 100.

[0030] Both the front end cover 1 and the rear end cover 2 are set in an inverted U shape, made of stamping parts or welded plates, and have the same shape and size settings.

[0031] The cover plate of the middle cover 3 is pressed into a corrugated shape, and the dimensions of the radian R and the groove depth H on the corrugated shape match the dimensions of the coupling. A larger one is selected for a large-sized coupling and a smaller one for a small-sized coupling.

[0032] The fixing screw holes on the front end cover 1, the middle cover 3, and the rear end cover 2 are processed by the tapping process.

[0033] The 2 fixing angle irons 4 are set in an L shape.

[0034] Since the oblong holes 6 are provided on the front end cover 1 and the rear end cover 2 of the coupling cover of the present utility model, an axial length of 2L can be adjusted. When the coupling cover of the present utility model is installed, the actual axial installation dimensions of the pump and the motor can be measured first. Place the coupling cover of the present utility model on the flat plate, loosen the fixing screws 5 on the front end cover 1 / rear end cover 2, and the front end cover 1 / rear end cover 2 can be axially micro-adjusted. After adjusting the axial dimensions, tighten the fixing screws 5 and install the coupling cover of the present utility model on the pump base. In this way, after adjustment, the coupling cover of the present utility model will no longer have problems such as not being able to be installed or having too large an end gap. At the same time, since the cover plate of the middle cover 3 is in a corrugated shape, the rigidity of the coupling is greatly improved, and the safety of the pump unit during use is also improved.

[0035] Those of ordinary skill in the art in this technical field should recognize that the above embodiments are only used to illustrate the present utility model, rather than to limit the present utility model. As long as within the scope of the substantial spirit of the present utility model, changes and modifications to the above-described embodiments will fall within the scope of the claims of the present utility model.
