Description

Technical Field

[0001] The present application relates to the technical field of needle roller bearing grease equipment, in particular to a needle roller bearing grease head. Background Art

[0002] In order to reduce the friction coefficient between the needle roller and the raceway of the bearing, a certain amount of grease is usually added between the needle roller and the raceway of the bearing during the bearing production process or after the bearing has been used for a period of time. The conventional grease adding method is to use a grease gun to add grease. A grease outlet hole is opened on the surface of the grease head of the grease gun. The grease is squeezed out by the extrusion force and squeezed into the needle roller and the raceway. The grease gun is usually composed of an oil pipe, a grease head, a handle, an oil suction rod, an exhaust valve, and other structures.

[0003] However, this grease adding method makes it difficult for users to find the position between the needle roller and the raceway when greasing the installed needle roller bearing due to insufficient light in the operating environment. At the same time, since the grease gun grease head of the grease gun is used without a filter device, and the grease itself contains impurities or is accidentally mixed with impurities during use, it is very easy to cause the grease gun grease head to be blocked, which is very inconvenient to clear, especially for manual grease guns. Once blocked, it cannot be used normally. Therefore, it is necessary to design a needle roller bearing grease head to solve the above problems.

[0004] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

DETAILED DESCRIPTION

[0030] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0032] like Figure 1-Figure 2 As shown, the needle bearing grease head in the present application includes a grease head 1, which is used to add grease to the needle bearing, a connector 11 is threadedly connected to one end of the grease head 1, and the connector 11 is used to connect to the barrel of a grease gun, and an extrusion head 2 is fixedly installed inside the grease head 1, and the extrusion head 2 is used to set the grease extrusion shape;

[0033] like Figure 2 As shown, a filter structure 5 is clamped on one end of the extruder head 2 near the connector 11, and the filter structure 5 includes a filter net bag 51 clamped and installed on one end of the extruder head 2 near the connector 11, and a clamping groove 511 adapted to the outer diameter of the extruder head 2 is opened on one side of the filter net bag 51 near the extruder head 2;

[0034] In the present application, a sealing ring is provided on one side of the filter net bag 51 close to the connecting head 11 to increase the sealing performance of the connection between the connecting head 11 and the grease head 1 .

[0035] like Figure 3 As shown, a lighting structure 3 is sleeved on the connecting head 11, and the lighting structure 3 includes a fixing ring 31 sleeved on the connecting head 11, and two sets of symmetrical cutting surfaces are provided on the end of the connecting head 11 away from the grease head 1, and a slot matched with the cutting surface is opened on the fixing ring 31 (not marked in the figure), and a fixing seat 32 is fixedly installed on the fixing ring 31, and a battery box 33 is fixedly installed on the fixing seat 32, and the battery box 33 has a power supply battery, and a pillar 34 is fixedly installed on the battery box 33, and a lighting lamp 35 is installed on the pillar 34, and the lighting lamp 35 is electrically connected to the power supply battery. At the same time, the lighting lamp 35 is used to illuminate the grease head 1 when greasing, and a switch 36 is installed on the lighting lamp 35, and the switch 36 is used to control the opening and closing of the lighting lamp 35.

[0036] like Figure 4 As shown, a telescopic structure 4 is fixedly installed on the grease head 1, and the telescopic structure 4 includes three groups of first connecting pieces 41 fixedly installed on the grease head 1, and a positioning rod 42 is fixedly installed on the first connecting piece 41, and the positioning rod 42 has a tray (not marked in the figure), and a spring 43 is sleeved on the positioning rod 42, and one end of the spring 43 is fixedly connected to the tray, and a scratching part 45 is movably sleeved on the grease head 1, and the scratching part 45 is made of transparent material so as to be suitable for passing the light beam emitted by the lighting lamp 35, and a second connecting piece 44 is bolted to the scratching part 45, and the positioning rod 42 penetrates the second connecting piece 44, and one end of the spring 43 is connected to a side of the second connecting piece 44 close to the first connecting piece 41.

[0037] When the grease gun grease head 1 is in use, the grease gun is held so that the grease head 1 is aligned and inserted into the gap between the needle roller and the raceway. Since the scraping portion 45 is flush with the grease head 1, when the grease head 1 is inserted between the needle roller and the raceway, the scraping portion 45 moves to a position close to the first connecting piece 41 and compresses the spring 43 to maintain the stability of the grease head 1.

[0038] The handle of the grease gun is then pressed to allow the grease to enter the grease head 1 through the oil pipe. The grease entering the grease head 1 is filtered by the filter net bag 51 and then squeezed out through the extrusion head 2 into between the needle roller and the raceway, thereby sequentially squeezing the grease into the needle roller and the raceway along the inner ring of the needle roller bearing. When the grease head 1 is pulled out from between the needle roller bearings, the grease is attached to the grease head 1. At this time, the scratching portion 45 slides on the grease head 1 through the inertia of the spring 43 to scratch the grease attached to the surface of the grease head 1.

[0039] When the light in the needle roller bearing installation environment is insufficient, the lighting lamp 35 can be activated by pressing the switch 36 to provide auxiliary lighting between the needle roller and the raceway of the needle roller bearing, so that the user can easily put the grease head 1 between the needle roller and the raceway, and the scraping part 45 can prevent the grease from contacting the lighting lamp 35;

[0040] In summary, by setting the filter net bag 51 and the card slot 511, the grease entering the extruder head 2 can be filtered, and by setting the lighting lamp 35, auxiliary lighting can be provided when the needle bearing installation environment is relatively dark. At the same time, by setting the scratching part 45 and the spring 43, the grease attached to the surface of the grease head 1 after use can be scratched.

[0041] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
