Therefore, there is a lot of room for improvement. Summary of the invention
[0003] The purpose of the present invention is to solve the above problems in the prior art and to provide a traction machine with oil leakage discharge.
[0004] The object of the present invention can be achieved by the following technical scheme: A traction machine with oil leakage discharge, comprising:
[0005] A machine base, which is provided with an oil storage tank;
[0006] The rotor has an oil leakage gap formed between it and the base, the oil storage tank is located on a side of the base close to the rotor, and the oil leakage gap is communicated with the oil storage tank;
[0007] A bearing, which is arranged on the rotor and close to the oil leakage gap;
[0008] When the bearing leaks oil, the oil enters the oil storage tank through the oil leakage gap.
[0009] In the above-mentioned traction machine with oil leakage drain, the machine base is further provided with an oil leakage channel, one end of the oil leakage channel is connected to the oil storage tank, and the other end of the oil leakage channel passes through the machine base and is connected to the outside.
[0010] In the above-mentioned traction machine with oil leakage drainage, the oil leakage channel is located at the bottom of the oil storage tank.
[0011] In the above-mentioned traction machine with oil leakage drainage, the oil leakage gap is an annular gap and the oil leakage gap is distributed around the axial direction of the machine base.
[0012] In the above-mentioned traction machine with oil leakage drain, a side of the machine base close to the rotor is recessed toward itself to form an oil leakage groove, and the oil leakage gap is located in the oil leakage groove.
[0013] In the above-mentioned traction machine with oil leakage drainage, a receiving portion is formed on a side of the oil storage tank away from the machine base, and the receiving portion exceeds the oil leakage gap and is located below one end of the rotor close to the machine base.
[0014] In the above-mentioned traction machine with oil leakage drainage, the connecting portion is arranged at an angle, and the height of the connecting portion gradually decreases in the distribution direction from being away from the machine base to being close to the machine base.
[0015] In the above-mentioned traction machine with oil leakage drainage, it also includes a brake shoe and a traction wheel, the traction wheel is connected to the rotor, the traction wheel is wound with a wire rope, and the rotor is provided with an anti-splash oil groove, the anti-splash oil groove is located between the brake shoe and the traction wheel to receive the splash oil of the wire rope.
[0016] In the above-mentioned traction machine with oil leakage drainage, the anti-splash oil groove is located on a side of the rotor close to the traction sheave.
[0017] In the above-mentioned traction machine with oil leakage drain, the anti-splash oil groove is an annular groove and the anti-splash oil groove is distributed around the axial direction of the rotor.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] 1. This traction machine with oil leakage discharge is provided with an oil leakage gap and an oil storage tank near the bearing, so that the oil leaked from the bearing enters the oil storage tank provided in the base through the oil leakage gap formed between the rotor and the base, and is discharged outside the traction machine through a certain path to avoid safety problems.
[0020] 2. The oil leakage channel is set in the machine base and is used to connect the oil storage tank with the outside world, so that the oil leaked from the bearing enters the oil storage tank set in the machine base through the oil leakage gap formed between the rotor and the machine base, and is discharged outside the traction machine through the oil leakage channel, further avoiding safety problems.
[0021] 3. The oil leakage gap is an annular gap and is distributed around the axial direction of the machine base. Therefore, when the bearing oil in the upper part of the bearing splashes onto the machine base, it can also slide along the annular machine base wall in the oil leakage gap and enter the oil storage tank set in the machine base.
[0022] 4. The receiving part exceeds the oil leakage gap and is located below one end of the rotor close to the base. It receives the bearing oil dripping within a certain range of the edge of the rotor to prevent the bearing oil from sliding along the edge of the rotor for a distance and then dripping.
[0023] 5. The height of the connecting part gradually decreases from far away from the machine base to close to the machine base, forming a slope structure, which plays a certain guiding role for the bearing oil and guides the bearing oil to slide into the oil storage tank along the connecting part.
[0024] 6. Adding an anti-splash oil groove on the rotor can allow the wire rope oil to be discharged through the anti-splash oil groove before splashing onto the brake shoe, preventing the wire rope oil from affecting the brake shoe and avoiding safety problems.
[0025] 7. The anti-splash oil tank is located on the side of the rotor close to the traction sheave. The splash oil of the wire rope is intercepted on the side closer to the traction sheave, so that the traction sheave will not be affected even if the anti-splash oil tank overflows.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
[0036] like Figure 1-Figure 3 As shown, a traction machine with oil leakage drainage includes: a machine base 100, a rotor 200 and a bearing 300.
[0037] The machine base 100 is provided with an oil storage tank 110 .
[0038] An oil leakage gap is formed between the rotor 200 and the base 100 , the oil storage tank 110 is located on a side of the base 100 close to the rotor 200 , and the oil leakage gap is communicated with the oil storage tank 110 .
[0039] The bearing 300 is disposed on the rotor 200 and is close to the oil leakage gap.
[0040] Specifically, when the bearing 300 leaks oil, the oil enters the oil storage tank 110 through the oil leakage gap.
[0041] In the prior art, during the operation of the traction machine, the bearing 300 leaks grease due to oil leakage or damage, and then flows into the interior of the traction machine to damage the insulation, and even contaminates the braking surface through a certain path to make the brake fail, thereby causing safety problems.
[0042] In this embodiment, the traction machine with oil leakage discharge is provided with an oil leakage gap and an oil storage tank 110 near the bearing 300, so that the oil leaked from the bearing 300 enters the oil storage tank 110 provided on the base 100 through the oil leakage gap formed between the rotor 200 and the base 100, thereby avoiding safety problems.
[0043] like Figure 1-Figure 3 As shown, based on the above embodiment, the machine base 100 is further provided with an oil leakage channel 120 , one end of which is connected to the oil storage tank 110 , and the other end of which passes through the machine base 100 and is connected to the outside.
[0044] In this embodiment, the oil leakage channel 120 is penetrated through the machine base 100 and is used to connect the oil storage tank 110 with the outside world, so that the oil leaked from the bearing 300 enters the oil storage tank 110 set in the machine base 100 through the oil leakage gap formed between the rotor 200 and the machine base 100, and is discharged outside the traction machine through the oil leakage channel 120, further avoiding safety problems.
[0045] like Figure 1-Figure 3 As shown, based on the above embodiment, the oil leakage channel 120 is located at the bottom of the oil storage tank 110 .
[0046] In this embodiment, the oil leakage channel 120 is located at the bottom of the oil storage tank 110, so as to timely discharge the oil of the bearing 300 in the oil storage tank 110 to prevent blockage.
[0047] like Figure 1-Figure 3 As shown, on the basis of the above embodiment, the oil leakage gap is an annular gap and the oil leakage gap is distributed around the axial direction of the machine base 100 .
[0048] In this embodiment, the oil leakage gap is an annular gap and is distributed around the axial direction of the machine base 100. Therefore, when the bearing 300 oil in the upper part of the bearing 300 splashes onto the machine base 100, it can also slide along the annular wall of the machine base 100 in the oil leakage gap and enter the oil storage tank 110 set in the machine base 100.
[0049] like Figure 1-Figure 3 As shown, on the basis of the above embodiment, a side of the base 100 close to the rotor 200 is recessed toward itself to form an oil leakage groove 130 , and the oil leakage gap is located in the oil leakage groove 130 .
[0050] In this embodiment, the oil leakage gap is actually the oil leakage groove 130 formed by a side of the rotor 200 being recessed toward itself, so there is no need to reserve a particularly precise distance between the base 100 and the rotor 200 or to make a groove on the rotor 200 .
[0051] like Figure 1-Figure 3 As shown, based on the above embodiment, a receiving portion 111 is formed on a side of the oil storage tank 110 away from the base 100 , and the receiving portion 111 exceeds the oil leakage gap and is located below one end of the rotor 200 close to the base 100 .
[0052] In this embodiment, the receiving portion 111 exceeds the oil leakage gap and is located below one end of the rotor 200 close to the base 100. By receiving the bearing 300 oil dripping within a certain range of the edge of the rotor 200, the bearing 300 oil is prevented from sliding along the edge of the rotor 200 for a distance and then dripping.
[0053] like Figure 1-Figure 3As shown, on the basis of the above embodiment, the receiving portion 111 is arranged to be inclined, and the height of the receiving portion 111 gradually decreases from being away from the base 100 to being close to the base 100.
[0054] In this embodiment, the height of the receiving portion 111 gradually decreases from being away from the machine base 100 to being close to the machine base 100, forming a slope structure, thereby playing a certain guiding role for the oil in the bearing 300, guiding the oil in the bearing 300 to slide into the oil storage tank 110 along the receiving portion 111.
[0055] like Figure 1-Figure 3 As shown, on the basis of the above embodiment, it also includes a brake shoe 400 and a traction wheel 500, the traction wheel 500 is connected to the rotor 200, the traction wheel 500 is wound with a wire rope, and the rotor 200 is provided with an anti-splash oil groove 210, the anti-splash oil groove 210 is located between the brake shoe 400 and the traction wheel 500 to receive the splash oil of the wire rope.
[0056] In the prior art, since the steel wire rope contains grease, oil may splash out during operation and may also contaminate the braking surface through a certain path.
[0057] In this embodiment, an anti-splash oil groove 210 is added to the rotor 200, so that the wire rope oil can be discharged through the anti-splash oil groove 210 before splashing onto the brake shoe 400, thereby preventing the wire rope oil from affecting the brake shoe 400 and avoiding safety problems.
[0058] like Figure 1-Figure 3 As shown, on the basis of the above embodiment, the anti-splash oil groove 210 is located on a side of the rotor 200 close to the traction sheave 500 .
[0059] In this embodiment, the anti-splash oil tank 210 is located on the side of the rotor 200 close to the traction wheel 500, and the wire rope splash oil is intercepted on the side closer to the traction wheel 500, so that the anti-splash oil tank 210 will not affect the traction wheel 500 even if it overflows.
[0060] like Figure 1-Figure 3 As shown, on the basis of the above embodiment, the anti-splash oil groove 210 is an annular groove and the anti-splash oil groove 210 is distributed around the axial direction of the rotor 200 .
[0061] In this embodiment, the anti-splash oil groove 210 is an annular groove and is distributed around the axial direction of the rotor 200. Therefore, when the oil on the wire rope above the traction wheel 500 splashes to the anti-splash oil groove 210, it can also slide along the annular anti-splash oil groove 210 and drip under itself without affecting the traction wheel 500.
