[0004] The purpose of this application is to address the above-mentioned problems existing in the prior art and to propose a bearing bracket that is easy to oil fill.

[0005] The present application can be implemented through the following technical scheme: a bearing bracket that is easy to fill with oil, including a mounting seat, the mounting seat is penetrated by a plurality of connecting holes and a receiving hole, the receiving hole is used to receive the bearing, an oil guide pipe is arranged in the mounting seat, an oil guide hole is arranged on the axial outer wall of the bearing, and the lubricating oil located outside the mounting seat can enter the oil guide hole through the oil guide pipe.

[0006] In the above technical solution, the receiving hole is used for inserting the bearing so that the bearing position is fixed. The through hole is used for inserting the bolt, and the user can fix the mounting seat on the specified object by the combination of the bolt and the nut. By arranging the oil guide pipe on the mounting seat and the oil guide hole on the bearing, the lubricating oil outside the mounting seat can flow through the oil guide pipe to the oil guide hole to lubricate the bearing, which is more convenient.

[0007] Furthermore, a accommodating cavity is provided in the mounting seat, and the mounting seat is also provided with an oil filling pipe, and the lubricating oil outside the mounting seat can enter the accommodating cavity and the oil guide pipe through the oil filling pipe, and the oil filling pipe is installed with a plug, and a rubber ring is adhered to the mounting seat, and a sliding rod is passed through the rubber ring, and a sealing plug is fixedly installed at the bottom of the sliding rod, and the inner ring of the rubber ring can fit the outer wall of the sliding rod in the length direction, and the sliding rod is pushed to make the sealing plug move linearly to seal or move away from the oil guide pipe.

[0008] In the above technical solution, the accommodating chamber can store lubricating oil. When it is necessary to fill the oil guide hole with oil, the sliding rod can be pulled outward to move the sealing plug away from the oil guide pipe. After the oil filling is completed, the sliding rod can be pushed inward to seal the oil guide pipe with the sealing plug. When the lubricating oil in the oil storage tank is exhausted, the inside of the accommodating chamber can be filled with oil through the oil filling pipe. By providing a rubber ring, the rubber ring has sealing properties, so that when the mounting seat is used in any posture, the lubricating oil in the accommodating chamber is not easy to flow out to the outside of the mounting seat.

[0009] Furthermore, the mounting seat is provided with an observation port communicating with the outside of the mounting seat and the accommodating cavity, and the observation port is clamped with a plate, and the plate is made of a transparent material.

[0010] In the above technical solution, the amount of remaining lubricating oil in the accommodating cavity can be observed through the observation port, which is more convenient.

[0011] Furthermore, the mounting seat is provided with a conical end connected to the interior of the accommodating cavity, the oil guide pipe is located below the conical end and connected to the interior of the conical end, the cross-sectional area of ​​the end of the conical end close to the ground is smaller than the cross-sectional area of ​​the end of the conical end away from the ground, and the inner circumference of the projection of the end of the conical end close to the ground on the horizontal plane is inscribed in the inner circumference of the projection of the accommodating cavity on the same horizontal plane.

[0012] In the above technical solution, the truncated cone end can make the lubricating oil in the accommodating cavity leave the interior of the accommodating cavity more fully. The oil guide pipe is located below the truncated cone end and is connected to the interior of the truncated cone end, and the inner circumference of the projection of the end of the truncated cone end close to the ground on the horizontal plane is inscribed in the inner wall of the accommodating cavity projected on the same horizontal plane. This design can make the lubricating oil in the accommodating groove and the truncated cone end easily enter the oil guide hole when the oil guide pipe is set vertically or the mounting seat is rotated 90 degrees clockwise around the axis of the accommodating hole (the oil guide pipe is in a horizontal state at this time).

[0013] Furthermore, the mounting seat includes a fixed block and a movable plate. The fixed block is provided with the accommodation hole, a plurality of connection holes and the accommodation cavity, the oil guide pipe is arranged in the fixed block; the movable plate is detachably connected to the fixed block, the rubber ring is glued to the movable plate, the movable plate is provided with the oil injection pipe, and the oil injection pipe is connected to the outside of the fixed block and the accommodation cavity.

[0014] In the above technical solution, it is difficult to directly open the accommodating cavity on the mounting seat. By providing a movable plate and a fixed block, workers can directly open the accommodating cavity on the fixed block, and then connect the movable plate to the fixed block, which is more convenient.

[0015] Furthermore, a positioning strip is formed on the mounting seat, and a sliding groove is formed on the axial outer wall of the bearing. The positioning strip can be slidably connected to the sliding groove so that the oil guide hole can be directly opposite to the oil guide pipe.

[0016] In the above technical solution, the positioning strip is slidably connected with the slide groove to allow the bearing to be inserted into the accommodating hole. At this time, the oil guide hole can be directly opposite to the oil guide pipe, which is more convenient.

[0017] Furthermore, a rubber pad is adhered to the fixed block, the rubber pad is located between the fixed block and the movable plate and has a hole extending therethrough, and the hole is used for lubricating oil to enter the accommodating cavity.

[0018] In the above technical solution, when the fixed block is in direct contact with the movable plate, the contact surfaces of the two are often not smooth enough due to processing, which causes the lubricating oil in the accommodating cavity to flow to the outside of the fixed block. The rubber pad has a sealing effect, and the movable plate can contact the rubber pad, so that the lubricating oil in the accommodating cavity is not easy to flow to the outside of the fixed block when the fixed block is placed in any posture for use.

[0019] Furthermore, the stopper is a rubber stopper.

[0020] In the above technical solution, the rubber plug has good sealing performance, which further reduces the possibility of foreign dust and other impurities entering the oil filling pipe.

[0021] In summary, the present application has the following technical effects: the receiving hole is used for inserting the bearing so that the bearing position is fixed. The through hole is used for inserting the bolt, and the user can fix the mounting seat on the specified object by the combination of the bolt and the nut. By arranging the oil guide pipe on the mounting seat and the oil guide hole on the bearing, the lubricating oil outside the mounting seat can flow into the oil guide hole through the oil guide pipe to lubricate the bearing, which is more convenient.

[0026] Please refer to the attached drawings in the instruction manual. Figure 1One embodiment of the present application provides a bearing support that is easy to inject oil, including a mounting seat 1, the mounting seat 1 including a fixing block 15, the fixing block 15 is provided with a receiving hole 12 for placing the bearing 2 and three connecting holes 11 along its thickness direction, the axes of the three connecting holes 11 are consistent with the axes of the receiving hole 12, and the three connecting holes 11 are arranged around the receiving hole 12. The three connecting holes 11 can be used to pass bolts, when in use, the bolts can be passed through the connecting holes 11 and the designated object, and then the nuts and bolts are threadedly connected, and the three connecting holes 11 are operated in this way, so that the fixing block 15 can be fixed on the designated object, and by providing multiple connecting holes 11, the fixing block 15 can be fixed more firmly.

[0027] Please refer to the attached drawings in the instruction manual. Figure 1 and Figure 2 , a accommodating chamber 13 is also provided in the fixed block 15, and the accommodating chamber 13 is used to store lubricating oil and can be communicated with the outside of the fixed block 15. A truncated cone end 14 is also provided in the fixed block 15 and is communicated with the inside of the accommodating chamber 13. The cross-sectional area of ​​the end of the truncated cone end 14 close to the ground is smaller than the cross-sectional area of ​​the end of the truncated cone end 14 far from the ground. The inner circumference of the projection of the end of the truncated cone end 14 close to the ground on the horizontal plane is inscribed in the inner circumference of the projection of the accommodating chamber 13 on the same horizontal plane. Among them, the accommodating chamber 13 is cylindrical, and the circumference of the upper end of the truncated cone end 14 is the same as the circumference of the accommodating chamber 13. An oil guide pipe 3 is also provided in the fixed block 15. The oil guide pipe 3 is located below the truncated cone end 14 and has an inner diameter that is the same as the circumference of the lower end of the truncated cone end 14. The oil guide pipe 3 is communicated with the inside of the truncated cone end 14. This design allows the lubricating oil in the accommodating cavity 13 and the truncated cone end 14 to easily enter the oil guide tube 3 when the oil guide tube 3 is vertically arranged and the fixing block 15 is rotated 90 degrees around the axis of the accommodating hole 12 (at this time, the oil guide tube 3 is in a horizontal state). Among them, an oil guide hole 21 is provided on the axial outer wall of the bearing 2, and the lubricating oil in the oil guide tube 3 can enter the oil guide hole 21 to lubricate the rollers of the bearing 2.

[0028] Please refer to the attached drawings in the instruction manual. Figure 1 A positioning strip 18 is formed on the fixing block 15, and the length direction of the positioning strip 18 is consistent with the axial direction of the accommodating hole 12, and a slide groove 22 is formed on the axial outer wall of the bearing 2, and the length direction of the slide groove 22 is consistent with the axial direction of the bearing 2. The positioning strip 18 can be slidably connected with the slide groove 22 so that the oil guide hole 21 can be aligned with the oil guide pipe 3. This design is convenient for workers to align the oil guide hole 21 with the oil guide pipe 3.

[0029] Please refer to the attached drawings in the instruction manual. Figure 2A rubber pad 10 is adhered to the outer wall of the fixed block 15. The upper surface of the rubber pad 10 contacts a movable plate 16. The movable plate 16 and the fixed block 15 are threadedly connected with the same screw 17, so that the movable plate 16 is fixed relative to the fixed block 15. After the movable plate 16 is installed on the fixed block 15, the contact surface between the two is often not processed flat enough, which causes the lubricating oil to flow out of the fixed block 15. The rubber pad 10 has a sealing effect, which can reduce the possibility of the lubricating oil in the accommodating chamber 13 flowing to the outside of the fixed block 15. An oil injection pipe 7 is provided on the movable plate 16. The oil injection pipe 7 can connect the accommodating chamber 13 and the outside of the movable plate 16. When the lubricating oil in the accommodating chamber 13 is exhausted, the lubricating oil can be directly injected into the accommodating chamber 13 through the oil injection pipe 7, which is more convenient. The oil injection pipe 7 is clamped with a plug 19, which is a rubber plug. After the oil injection is completed, the plug 19 can be clamped with the oil injection pipe 7 to reduce the possibility of foreign dust and other impurities entering the oil injection pipe 7.

[0030] Please refer to the attached drawings in the instruction manual. Figure 2 The rubber pad 10 is penetrated by a hole 101, the axis of the hole coincides with the axis of the accommodating chamber 13, and the hole 101 is used to allow lubricating oil to enter the accommodating chamber 13. The movable plate 16 is bonded with a rubber ring 4, and the rubber ring 4 is penetrated by a slide bar 5, and the inner ring of the rubber ring 4 can abut against the outer wall of the length direction of the slide bar 5 at any place. A sealing plug 6 is detachably installed at the bottom of the slide bar 5, and the sealing plug 6 is located inside the accommodating chamber 13. The slide bar 5 is pushed to make the sealing plug 6 move linearly, so that the sealing plug 6 blocks or keeps away from the oil guide pipe 3. By setting the rubber ring 4, the rubber ring 4 has a sealing effect, so that when the accommodating chamber 13 is used in a horizontal or vertical state, the lubricating oil in the accommodating chamber 13 is not easy to leak out from between the movable plate 16 and the slide bar 5.

[0031] Please refer to the attached drawings in the instruction manual. Figure 1 The fixed block 15 is provided with an observation port 8 which is connected to the outside of the fixed block 15 and the accommodating chamber 13. The observation port 8 is arranged on one end surface of the fixed block 15. The observation port 8 is clamped with a plate 9, which is made of a transparent material and can be a transparent acrylic plate. The observation port 8 is in a long strip shape and is arranged vertically, so that the worker can observe the amount of lubricating oil in the accommodating chamber 13.

[0032] The working principle of this embodiment is as follows: first, fix the fixing block 15 on the designated object, then slide the positioning bar 18 and the slide groove 22 together to make the bearing 2 fit into the receiving hole 12. When oil filling is required, pull the slide bar 5 outward along the length direction of the slide bar 5 to make the sealing plug 6 away from the oil guide pipe 3. At this time, the lubricating oil in the receiving chamber 13 can enter the oil guide hole 21 through the oil guide pipe 3. After the oil filling is completed, push the slide bar 5 inward to make the sealing plug 6 block the oil guide pipe 3 so that the oil guide pipe 3 stops entering the lubricating oil. When the lubricating oil in the receiving chamber 13 is exhausted, pull out the plug 19 and then fill the receiving chamber 13 with oil through the oil filling pipe 7, which is more convenient.

[0033] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
