Description

Technical Field

[0001] This utility model relates to a lubrication device for enameled wire, and more particularly to a lubrication device for anti-volatile enameled wire. Background Technology

[0002] Currently, there are two types of lubrication devices used for enameled wire. The first type involves installing felt sheets completely soaked in lubricating oil on both the top and bottom sides of the enameled wire, allowing the wire to pass between the felt sheets for lubrication. The second type involves installing a lubricating oil groove below the enameled wire, within which a continuously rotating lubricating oil roller draws the lubricating oil upwards and adheres it to the surface of the enameled wire. However, both of these lubrication devices inevitably result in a large area of ​​contact between the lubricating oil and the outside air, thus increasing the evaporation rate and consumption of the lubricating oil.

[0003] To address the aforementioned shortcomings, some manufacturers currently install covers on the outside of the lubrication device to shield it, thereby reducing the evaporation rate of the lubricating oil. However, after installation, the effect of these covers is limited, and they can also easily cause the enameled wire to collide with each other at the edge of the cover due to vibration, thus affecting the processing quality of the enameled wire.

[0004] In addition, lubricating the enameled wire with felt sheets can easily cause the felt sheets to age and deform after long-term use, and the amount of lubricating oil soaked in the contact area between the felt sheets and the enameled wire will also be relatively reduced. In other words, it is difficult to ensure that the felt sheets maintain close contact and stable lubrication of the enameled wire after long-term use.

[0005] Therefore, there is a need for a lubrication device for enameled wires that can reduce the evaporation rate of lubricating oil. Utility Model Content

[0006] The purpose of this invention is to provide a lubrication device for enameled wires that prevents evaporation. It effectively reduces the contact area between the lubricating oil and the external air, thereby slowing down the evaporation rate of the lubricating oil.

[0007] The technical solution of this utility model is as follows: a lubrication device for anti-volatile enameled wire, including a lubricating oil box, a lubrication cavity for containing lubricant formed inside the lubricating oil box, a first oil outlet provided on the top of the lubricating oil box, a felt mounting bracket detachably connected to the lubricating oil box provided outside the first oil outlet, a plurality of second oil outlets distributed at intervals along the length direction of the lubricating oil box on the felt mounting bracket, an insertion groove formed in the felt mounting bracket above the second oil outlet, a felt strip fastened in the insertion groove, the lower end of the felt strip passing through the second oil outlet and the first oil outlet in sequence and extending into the lubrication cavity.

[0008] In the aforementioned anti-volatile enameled wire lubrication device, the end of the felt strip is fastened to the insertion groove via a stepped portion, and a gap is formed in the middle of the stepped portion for the enameled wire to pass through.

[0009] In the aforementioned anti-volatile enameled wire lubrication device, the felt mounting brackets on both sides of the stepped portion are provided with U-shaped grooves for the enameled wire to pass through.

[0010] In the aforementioned anti-volatile enameled wire lubrication device, the felt mounting brackets are symmetrically arranged side by side on the mounting seats on both sides of the first oil outlet. The mounting seats have an L-shaped cross-section. The mounting seats on both sides are connected to each other by partitions. Every two partitions and the mounting seats on both sides form a plug-in groove after being enclosed. Adjacent plug-in grooves are separated from each other by partitions.

[0011] In the aforementioned anti-volatile enameled wire lubrication device, the cross-sectional shape of the partition is T-shaped, and the two sides of the stepped portion are fastened to the partition.

[0012] In the aforementioned anti-volatile enameled wire lubrication device, the top of the partition is fastened with a spring piece, the two ends of the spring piece extend into the insertion slots on both sides and form an inclined pressing part, the end of the pressing part is provided with a bending plate, the stepped part is fastened to the bending plate and the two side walls of the stepped part are respectively in contact with the pressing parts of the spring pieces on both sides.

[0013] In the aforementioned anti-volatile enameled wire lubrication device, the bottom of the lubricating oil box forms an oil inlet, and the outside of the oil inlet is connected to a lubricating oil pump via an oil inlet pipe.

[0014] In the aforementioned anti-volatile enameled wire lubrication device, an oil outlet pipe is connected to the bottom of the lubricating oil box on the side of the oil inlet. One end of the oil outlet pipe is connected to a ball valve and a liquid level pipe via a three-way connector. The liquid level pipe is made of transparent material and extends vertically upward to the top of the lubricating oil box.

[0015] Compared with the prior art, this utility model has the following characteristics:

[0016] (1) This utility model, through the cooperation of the lubricating oil box, the felt mounting bracket and the felt strip, enables the felt strip to absorb the lubricating oil in the lubricating oil box to the top of the lubricating oil box after insertion, and to lubricate the enameled wire passing through the middle of the felt strip, thus realizing the lubrication function; the felt mounting bracket and the lubricating oil box can wrap the felt strip around its perimeter, so that the felt strip only contacts the outside air through its top surface, which can greatly reduce the contact area with the outside air compared with the existing exposed felt sheet structure, thereby reducing the evaporation rate of the lubricating oil;

[0017] (2) Based on the above, the present invention further defines the structure of the felt mounting frame, thereby reducing the processing difficulty of the felt mounting frame on the one hand; on the other hand, it can use the cooperation of the mounting base and the partition to fasten and support the felt strip, thereby effectively preventing the possibility of the felt strip shifting and moving, and improving the installation stability of the felt strip.

[0018] (3) Through the structural cooperation of the step and the spring, the spring can also apply a squeezing force to the felt strip from both sides towards the enameled wire after installation. This makes the felt strip tightly adhere to the enameled wire under the squeezing force, reducing the possibility of the felt strip separating from the enameled wire due to aging and deformation after long-term use. On the other hand, it can also squeeze and limit the height of the felt strip, thereby preventing the enameled wire from driving the felt strip upward during the up and down vibration, further improving the installation stability of the felt strip.

[0019] Therefore, this invention can effectively reduce the contact area between lubricating oil and external air, thereby reducing the evaporation rate of lubricating oil. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0027] Example 1. A lubrication device for anti-volatile enameled wire, configured as follows: Figure 1-3As shown, the device includes a lubricating oil box 1, which contains a lubrication cavity for containing lubricant. The top of the lubricating oil box 1 is provided with a long strip-shaped first oil outlet 2. The outside of the first oil outlet 2 is provided with a felt mounting bracket 3 for connecting the lubricating oil box 1 with screws. Several second oil outlets 4 are distributed at intervals along the length of the lubricating oil box 1 on the felt mounting bracket 3. An insertion groove 5 is formed in the felt mounting bracket 3 above the second oil outlet 4. A felt strip 6 is fastened and connected in the insertion groove 5. Each felt strip 6 is used to lubricate a single enameled wire. The lower end of the felt strip 6 passes through the second oil outlet 4 and the first oil outlet 2 in sequence and extends into the lubrication cavity.

[0028] The end of the felt strip 6 is fastened to the insertion groove 5 via a stepped portion, and the middle of the stepped portion is cut open with scissors to form a gap for the enameled wire to pass through.

[0029] The felt mounting brackets 3 on both sides of the stepped section are provided with U-shaped grooves 7 for enameled wires to pass through.

[0030] The felt mounting frame 3 is symmetrically arranged on both sides of the first oil outlet 2 with mounting seats 301. The L-shaped cross-section of the mounting seat 301 is formed by bending the plate. The two mounting seats 301 are connected to each other by partition 302. The two ends of the partition 302 are welded to the two mounting seats 301 respectively. After two partitions 302 and the two mounting seats 301 are enclosed, they form a plug groove 5. Adjacent plug grooves 5 are separated from each other by partition 302.

[0031] The partition 302 has a T-shaped cross-section, and the two sides of the stepped portion are fastened to the partition 302.

[0032] The bottom of the lubricating oil box 1 forms an oil inlet 9, and the outside of the oil inlet 9 is connected to a lubricating oil pump via an oil inlet pipe. The lubricating oil is periodically pumped into the lubrication chamber by the lubricating oil pump.

[0033] In this embodiment, during installation, the operator cuts each felt strip 6 into the specified shape and inserts it into the insertion slot 5, ensuring that the lower end of the felt strip 6 extends through the second oil outlet 4 and the first oil outlet 2 into the lubrication cavity. After insertion, the felt strip 6 can absorb the lubricating oil in the lubrication cavity, keeping the stepped portion at the top of the felt strip 6 moist during use.

[0034] In this embodiment, during use, each enameled wire extends from the U-shaped groove 7 into the insertion groove 5 and passes through the gap in the middle of the stepped portion, allowing the stepped portion to coat the surface of the enameled wire with lubricating oil, thus achieving a lubrication effect. During lubrication, the felt strip 6, through the cooperation of the felt mounting bracket 3 and the lubricating oil box 1, can shield the perimeter of the felt strip 6, with only the top surface of the felt strip 6 in contact with the outside air, thereby significantly reducing the evaporation efficiency of the lubricating oil.

[0035] Example 2. A lubrication device for anti-volatile enameled wire, configured as follows: Figure 4 and 5 As shown, the device includes a lubricating oil box 1, which contains a lubrication cavity for containing lubricant. The top of the lubricating oil box 1 is provided with a long strip-shaped first oil outlet 2. The outside of the first oil outlet 2 is provided with a felt mounting bracket 3 that is detachably connected to the lubricating oil box 1. Several second oil outlets 4 are distributed at intervals along the length of the lubricating oil box 1 on the felt mounting bracket 3. An insertion groove 5 is formed in the felt mounting bracket 3 above the second oil outlet 4. A felt strip 6 is fastened and connected in the insertion groove 5. The lower end of the felt strip 6 passes through the second oil outlet 4 and the first oil outlet 2 in sequence and extends into the lubrication cavity.

[0036] The end of the felt strip 6 is fastened to the insertion groove 5 via a stepped portion. The middle of the stepped portion is cut open with scissors to form a gap for the enameled wire to pass through, and the gap extends to the bottom of the insertion groove 5.

[0037] The felt mounting brackets 3 on both sides of the stepped section are provided with U-shaped grooves 7 for enameled wires to pass through.

[0038] The felt mounting frame 3 is symmetrically arranged side by side on the mounting seats 301 on both sides of the first oil outlet 2. The mounting seats 301 have an L-shaped cross-section. The two mounting seats 301 are connected to each other by a partition 302. The two ends of the partition 302 are welded to the two mounting seats 301 respectively. After two partitions 302 and the two mounting seats 301 are enclosed, they form a plug-in groove 5. Adjacent plug-in grooves 5 are separated from each other by the partition 302.

[0039] The top of the partition 302 is fastened with a spring piece 8. After being fastened, the spring piece 8 is fixed to the top of the partition 302 by compression deformation, so that it will not fall off with the movement of the enameled wire. The two ends of the spring piece 8 extend into the two side insertion slots 5 and form an inclined compression part 801. A gap is formed between the compression part 801 and the partition 302 for the compression part 801 to deform inward. The end of the compression part 801 is provided with a bending plate 802. The stepped part is fastened to the bending plate 802 and the two side walls of the stepped part are respectively in contact with the compression parts 801 of the two spring pieces 8.

[0040] The bottom of the lubricating oil box 1 forms an oil inlet 9, and the outside of the oil inlet 9 is connected to the lubricating oil pump via an oil inlet pipe.

[0041] The bottom of the lubricating oil box 1 on one side of the oil inlet 9 is connected to an oil outlet pipe 10. One end of the oil outlet pipe 10 is connected to a ball valve 11 and a liquid level pipe 12 via a three-way connector. The liquid level pipe 12 is made of transparent material and extends vertically upward to the top of the lubricating oil box 1. Operators can observe the amount of lubricating oil in the lubrication chamber in real time through the liquid level pipe 12, and the lubricating oil in the lubrication chamber can be discharged through the ball valve 11.

[0042] Compared to Embodiment 1, this embodiment uses spring pieces 8 on both sides of the stepped portion. After installation, the spring pieces 8 can compress the stepped portion from both sides. This causes the stepped portion to deform slightly under the compressive force and converge towards the enameled wire, thus improving the wrapping effect on the enameled wire. On the other hand, the compression of the spring pieces 8 can also use friction to limit the felt strip 6, ensuring the positional stability of the felt strip 6 and providing lubrication for the enameled wire.
