Description

Technical Field

[0001] The present application relates to the technical field of chucks, and in particular to a chuck gear lubrication assembly. Background Art

[0002] The chuck is a mechanical device used by machine tools to clamp workpieces. It is a machine tool accessory that uses the radial movement of the movable jaws evenly distributed on the chuck body to clamp and position the workpiece. The chuck includes a chuck body, a movable jaw is provided on one side of the chuck body, and a jaw drive mechanism is provided on the other side of the chuck body. The movable jaw is controlled to rotate by the jaw drive mechanism. The jaw drive mechanism includes a motor and a chuck gear. The chuck gear is divided into a driving gear and a driven gear. The motor drives the driving gear to rotate, and the driven gear meshed with the driving gear drives the movable jaw to rotate coaxially. In order to make the meshing rotation between the driving gear and the driven gear smoother, the chuck gear lubrication assembly, as one of the key mechanical components, plays an important role in ensuring the stable operation of the equipment.

[0003] At present, the prior art chuck gear lubrication scheme usually uses lubricating oil or grease for lubrication. The chuck gear is divided into a driving gear and a driven gear. The driving gear and the driven gear are arranged on these gears. The lubricant is sprayed on the gear surface to reduce friction and wear between the gears and ensure the normal operation of the equipment.

[0004] However, this method has certain defects: during the lubrication process of the driving gear and the driven gear, the lubricating oil is easily sprayed to the places where the driving gear and the driven gear do not need lubrication, causing the problem of lubricating oil waste and leading to poor lubrication effect. Utility Model Content

[0005] In order to address the deficiencies in the prior art, the present application provides a chuck gear lubrication assembly that can reduce the waste of lubricating oil and improve the smoothness of the outer surface of the driven gear.

[0006] The present application provides a chuck gear lubrication assembly adopting the following technical solution:

[0007] A chuck gear lubrication assembly comprises a lubrication gear, which is meshed with a driven gear of a chuck, an oil injection shaft is rotated and penetrated through the center of the lubrication gear, one end of the oil injection shaft is fixedly connected to a chuck body on one side of the driven gear, a first oil outlet hole is provided in each tooth groove of the lubrication gear, an oil injection shaft is provided in the lubrication gear and an oil injection channel is provided, an oil storage tank is arranged outside the chuck body, and a hose at one end of the oil storage tank is connected to the oil injection channel.

[0008] By adopting the above technical scheme, the lubricating oil in the oil storage tank enters the oil filling shaft and then flows out from the oil filling channel. When the lubricating gear rotates to the point where the first oil outlet hole is connected to the oil filling channel, the lubricating oil flows out from the oil filling channel to the first oil outlet hole of the lubricating gear and then flows into the teeth and tooth grooves of the driven gear, and the lubricating oil is specifically soaked into the teeth and tooth grooves of the driven gear. Friction is generated by the meshing between the lubricating gear and the driven gear, thereby lubricating the driven gear, reducing the waste of lubricating oil and improving the smoothness of the outer surface of the driven gear.

[0010] By adopting the above technical solution, when the motor starts and indirectly drives the driven gear to rotate, the controller can control the peristaltic pump to start and squeeze out the lubricating oil in the oil storage tank, so that the lubricating oil flows into the oil filling shaft, so that the lubricating oil lubricates the driven gear only when the driven gear rotates, thereby reducing the waste of lubricating oil.

[0011] The present application further arranges: the teeth of the lubricating gear located at the meshing position between the lubricating gear and the driven gear are arranged as meshing teeth, and an oil outlet channel is formed when the oil filling passage of the oil filling shaft is connected with the first oil outlet hole, and the oil outlet channel is located between the lubricating gear and the driven gear and at the top of the meshing teeth.

[0012] By adopting the above technical solution, the position where the lubricating oil flows out from the lubricating gear can soak the driven gear in advance when the lubricating gear and the driven gear are in meshing friction, so that the driven gear can be fully lubricated when the lubricating gear and the driven gear are in meshing friction, thereby improving the efficiency of lubricating oil lubrication.

[0013] The present application further provides that: an oil filling chamber is opened inside the lubricating gear near the tooth side, the oil filling chamber is connected to the first oil outlet hole, and the oil filling chamber is connected to the oil filling channel when the oil outlet channel and the first oil outlet hole do not form an oil outlet channel.

[0014] By adopting the above technical solution, the oil filling cavity can accommodate part of the lubricating oil that fails to flow out from the first oil outlet hole, so as to reduce the waste of lubricating oil.

[0015] The present application further provides that: a groove is provided on the inner wall of the first oil outlet hole inside the lubrication gear.

[0016] By adopting the above technical solution, the lubricating oil can be more concentrated on the first oil outlet hole to flow out to the top of the driven gear teeth, so that the lubricating oil can flow from the top of the driven gear teeth to both sides of the teeth.

[0017] The present application further provides that: each tooth of the lubricating gear is provided with a second oil outlet hole on the side facing the tooth groove, and the second oil outlet hole is connected to the oil filling chamber.

[0018] By adopting the above technical solution, the lubricating oil in the oil filling chamber can flow out from the second oil outlet hole, that is, flow out from the side of the teeth of the lubricating gear, so that when the teeth of the driven gear are in contact with the teeth of the lubricating gear, the lubricating oil can flow out from the second oil outlet hole and specifically infiltrate the teeth of the driven gear.

[0019] The present application further provides that: each tooth groove of the lubrication gear is provided with a plurality of first oil outlet holes.

[0020] By adopting the above technical solution, the area of ​​the top of the teeth of the driven gear covered by the lubricating oil can be increased, so that the lubrication effect is better.

[0021] The present application further provides that: a plurality of second oil outlet holes are provided on both sides of a tooth of the lubrication gear.

[0022] By adopting the above technical solution, the area covered by the lubricating oil on both sides of the teeth of the driven gear can be increased, thereby achieving a better lubrication effect.

[0023] In summary, this application has the following beneficial effects:

[0024] The lubricating oil in the present application flows from the oil storage tank into the oil filling shaft, and then flows out from the oil filling channel of the oil filling shaft. When the lubricating gear rotates to the point where the first oil outlet hole is connected to the oil filling channel, the lubricating oil flows out from the oil filling channel of the oil filling shaft to the first oil outlet hole of the lubricating gear, and then flows into the top of the teeth and the tooth grooves of the driven gear, so that the lubricating oil is targetedly soaked into the teeth and tooth grooves of the driven gear. Friction is generated through the meshing between the lubricating gear and the driven gear, and the driven gear is lubricated, thereby avoiding waste of lubricating oil as much as possible, thereby improving the smoothness of the outer surface of the driven gear.

DETAILED DESCRIPTION

[0030] The following is combined with Figures 1 to 4 This application is described in further detail.

[0031] refer to Figures 1 to 3 In this embodiment, a chuck gear lubrication assembly includes a lubrication gear 2, which is meshed with a driven gear 13 of a chuck 1. An oil injection shaft 3 is rotated and penetrates the center of the lubrication gear 2. At this time, the axis of the oil injection shaft 3 and the axis of the lubrication gear 2 are on the same straight line. The lubrication gear 2 rotates around the oil injection shaft 3 through the meshed driven gear 13. One end of the oil injection shaft 3 is fixedly connected to the chuck body 10 on one side of the driven gear 13. The lubrication gear 2 is provided with a first oil outlet 20 in each tooth groove. The oil injection shaft 3 is provided with an oil injection channel 3 in the lubrication gear 2. 0. An oil storage tank 4 is fixedly connected to the outside of the chuck body 10. The oil storage tank 4 stores lubricating oil. A hose at one end of the oil storage tank 4 is connected to the oil filling passage 30. The lubricating oil flows from the hose of the oil storage tank 4 into the oil filling shaft 3, and then flows out from the oil filling passage 30 of the oil filling shaft 3 to the first oil outlet 20, and finally flows out and infiltrates the teeth and tooth grooves of the driven gear 13. When friction is generated in the meshing between the lubricating gear 2 and the driven gear 13, the lubricating oil can be spread out to make the lubricating oil more evenly distributed, thereby reducing the waste of lubricating oil and improving the smoothness of the outer surface of the driven gear 13.

[0032] refer to Figure 1 , Figure 3 and Figure 4 In this embodiment, a peristaltic pump 5 is fixedly connected to the outside of the chuck body 10, and a hose at one end of the oil storage tank 4 is connected to the oil injection channel 30 through the peristaltic pump 5. A controller is fixedly connected to the inside of the chuck body 10, and the controller is electrically connected to the motor 11. The controller is used to start and stop the peristaltic pump 5. The controller is electrically connected to the peristaltic pump 5. When the motor 11 starts, the controller controls the peristaltic pump 5 to start after receiving the start signal of the motor 11. When the motor 11 stops working, the controller controls the peristaltic pump 5 to stop working. When the driven gear 13 engaged with the driving gear 12 rotates, the peristaltic pump 5 provides the oil storage tank 4 with power to inject the lubricating oil into the oil injection shaft 3, so that the lubricating oil flows into the oil injection shaft 3. When the motor 11 stops working, the lubricating oil no longer flows into the oil injection shaft 3, thereby reducing the waste of lubricating oil.

[0033] Furthermore, the teeth of the lubricating gear 2 located in the meshing state between the lubricating gear 2 and the driven gear 13 are set as meshing teeth 21. When the oil filling passage 30 of the oil filling shaft 3 is connected with the first oil outlet hole 20, an oil outlet channel is formed. The oil outlet channel is located between the lubricating gear 2 and the driven gear 13 and is located at the top of the meshing teeth 21. When the lubricating oil flows from the oil outlet channel and the first oil outlet hole 20, the driven gear 13 can be soaked in advance when the lubricating gear 2 and the driven gear 13 are meshed and rubbed, so that the lubricating gear 2 and the driven gear 13 can be fully lubricated when the meshing friction occurs. The sliding driven gear 13 improves the efficiency of lubrication of the lubricating oil, and during the rotation of the lubricating gear 2 and the driven gear 13, the lubricating oil can easily fall from the teeth of the driven gear 13 to the outside at the end of the meshing point away from the oil outlet channel, and the lubricating oil at the outlet of the oil outlet channel is a distance away from the meshing point of the lubricating gear 2 and the driven gear 13. Therefore, the lubricating oil can pass through the friction generated by the meshing of the lubricating gear 2 and the driven gear 13 in this distance, and be evenly distributed on the teeth and tooth groove surfaces of the driven gear 13, thereby reducing the waste of lubricating oil.

[0034] In addition, an oil filling chamber 22 is opened inside the lubricating gear 2 near the tooth side, and the oil filling chamber 22 is connected with the first oil outlet hole 20. The oil filling chamber 22 is connected with the oil filling passage 30 when the oil outlet passage 30 and the first oil outlet hole 20 do not form an oil outlet channel. During the rotation of the lubricating gear 2, since the lubricating oil continuously flows out of the oil filling passage 30, the oil filling chamber 22 can accommodate part of the lubricating oil that fails to flow out of the first oil outlet hole 20, thereby reducing the waste of lubricating oil.

[0035] Furthermore, a groove 23 is provided on the inner wall of the first oil outlet hole 20 inside the lubrication gear 2. When the lubricating oil flows out from the oil filling channel 30, it can be more concentrated on the top of the teeth of the driven gear 13 at the first oil outlet hole 20, so that the lubricating oil can flow from the top of the teeth of the driven gear 13 to both sides of the teeth.

[0036] Furthermore, each tooth of the lubrication gear 2 is provided with a second oil outlet hole 24 on the side facing the tooth groove, and the second oil outlet hole 24 is connected to the oil filling chamber 22. The lubricating oil in the oil filling chamber 22 can flow out from the second oil outlet hole 24, and the second oil outlet hole 24 faces the teeth of the driven gear 13. Therefore, when the teeth of the driven gear 13 are in contact with the teeth of the lubrication gear 2, the lubricating oil can flow out from the second oil outlet hole 24, and specifically infiltrate the teeth of the driven gear 13, thereby increasing the area of ​​the lubricating oil infiltrating the teeth of the driven gear 13 and improving the smoothness of the outer surface of the driven gear 13.

[0037] In addition, each tooth groove of the lubricating gear 2 is provided with a plurality of first oil outlet holes 20, which can increase the area of ​​the top of the teeth of the driven gear 13 covered by the lubricating oil, and the lubricating oil can be more evenly distributed on the top of the teeth.

[0038] In addition, a plurality of second oil outlet holes 24 are provided on both sides of a tooth of the lubricating gear 2 , which can increase the area of ​​the lubricating oil covering both sides of the tooth of the driven gear 13 , and the lubricating oil can be more evenly distributed on both sides of the tooth of the driven gear 13 .

[0039] The implementation principle of the embodiment of the present application is: when the motor 11 of the chuck 1 is started, the controller controls the peristaltic pump 5 to start, and the lubricating oil in the oil storage tank 4 is sent into the oil filling shaft 3, and the lubricating oil then flows out from the oil filling channel 30 of the oil filling shaft 3. When the oil filling channel 30 and the first oil outlet hole 20 form an oil outlet channel, the lubricating oil flows out from the oil outlet channel to the teeth of the driven gear 13, and the lubricating oil flows along the top and both sides of the teeth of the driven gear 13 to the tooth grooves, and part of the lubricating oil enters the oil filling chamber 22 and flows into the second oil outlet hole 24, and flows out from the second oil outlet hole 24 to both sides of the teeth of the driven gear 13.

[0040] 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.
