On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0021] The oil injection device of the slewing bearing according to the embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0022] like Figure 1-Figure 3 As shown, the oil injection device of the slewing bearing according to the embodiment of the utility model may include an oil injection box 1, a motor 2, an oil squeezing component 3 and a joint control component 4.

[0023] The oil filling box body 1 is provided with a box cover 10 , the box cover 10 is provided with a mounting plate 100 , and the motor 2 is arranged on the mounting plate 100 .

[0024] It is understandable that, by providing the box cover 10, it is convenient to open the top of the oil filling tank opening, thereby facilitating the filling of butter.

[0025] It can be understood that, by disposing the mounting plate 100 , the output shaft of the motor 2 is reserved, so as to facilitate the installation of the joint control assembly 4 and the motor 2 .

[0026] One end of the oil squeezing assembly 3 is connected to the output shaft of the motor 2 and is rotatably and sealingly connected to the box cover 10 , and the other end of the oil squeezing assembly 3 is slidably connected to the inner wall of the oil filling box body 1 .

[0027] It should be noted that the oil squeezing assembly 3 described in this embodiment can squeeze out the butter in the oil filling box 1, so as to fill the inside of the slewing bearing with oil.

[0028] The linkage control assembly 4 may include a transmission mechanism 40 , a support member 41 and a driving member 42 .

[0029] Among them, one end of the transmission mechanism 40 is rotatably connected to the output shaft of the motor 2, and the other end of the transmission mechanism 40 is rotatably connected to the support member 41, the support member 41 is arranged on one side of the oil filling tank body 1, the driving member 42 is rotatably connected to the support member 41, and the driving member 42 is threadedly connected to the transmission mechanism 40.

[0030] It can be understood that, by disposing the support member 41 , the driving member 42 can be supported, so that the transmission mechanism 40 can control the driving member 42 in a linked manner, thereby realizing the driving control of the slewing bearing by the driving member 42 .

[0031] It can be understood that, through the arrangement of the transmission mechanism 40, the motor 2 can drive the oil squeezing assembly 3 to inject oil into the slewing bearing, and at the same time, drive the driving member 42 to rotate, so that it meshes and rotates with the external gear of the slewing bearing, thereby driving the rotation of the slewing bearing, thereby eliminating the need to manually rotate the external gear of the slewing bearing, thereby reducing the labor intensity of related personnel and improving the oil injection efficiency of the slewing bearing.

[0032] Specifically, in the actual operation process, the relevant personnel adjust the device, mesh the driving member 42 with the external gear of the slewing bearing, and start the device. The motor 2 drives the oil squeezing component 3 to work, and squeezes the butter in the oil filling box 1 into the slewing bearing. At the same time, the motor 2 drives the transmission mechanism 40 to rotate, and the transmission mechanism 40 drives the driving member 42 to rotate, so that the driving member 42 meshes and rotates with the external gear of the slewing bearing, thereby realizing the joint control rotation of the external gear of the slewing bearing, reducing the labor intensity of the relevant personnel, and improving the oil filling efficiency of the slewing bearing.

[0033] In one embodiment of the present invention, Figure 1-Figure 3 As shown, the transmission mechanism 40 may include a first pulley 400 , a second pulley 401 and a transmission belt 402 .

[0034] Among them, the first pulley 400 is rotatably set on the output shaft of the motor 2, the second pulley 401 is rotatably set on the support member 41, and the driving member 42 is threadedly connected to the second pulley 401, and the transmission belt 402 is rotatably connected to the first pulley 400 and the second pulley 401 respectively.

[0035] It should be noted that the driving member 42 described in this embodiment is threadedly fixedly connected to the second pulley 401, so as to ensure that the rotation of the second pulley 401 drives the rotation of the driving member 42, thereby ensuring the rotation of the slewing bearing outer gear.

[0036] In one embodiment of the present invention, Figure 1-Figure 3 As shown, the support member 41 may include a support plate 410 , a telescopic sleeve 411 and a limiting bolt 412 .

[0037] Among them, the support plate 410 is arranged on one side of the oil filling box body 1, one end of the telescopic sleeve 411 is arranged on the support plate 410, and the limit bolt 412 is arranged on one end of the telescopic sleeve 411, the other end of the telescopic sleeve 411 is rotatably connected to the first pulley 400, and the driving member 42 is rotatably connected to the other end of the telescopic sleeve 411.

[0038] It should be noted that the limiting bolt 412 described in this embodiment is arranged on one end of the non-extending axis of the telescopic sleeve 411, so as to limit and fix the extending axis of the telescopic sleeve 411, and through the setting of the telescopic sleeve 411, the present device is suitable for slewing bearings of different diameters, and according to the different telescopic lengths of the telescopic sleeve 411, relevant personnel select transmission belts 402 of different lengths to adapt to the rotational connection between the first pulley 400 and the second pulley 401, thereby improving the use effect of the present device.

[0039] In one embodiment of the present invention, Figure 1-Figure 3 As shown, the driving member 42 may include a threaded rod 420 and a driving gear 421 .

[0040] The threaded rod 420 is threadedly connected to the second pulley 401 , the threaded rod 420 is rotatably connected to the telescopic sleeve 411 , a fixing nut 4200 is provided on the threaded rod 420 , and a driving gear 421 is provided at the bottom of the threaded rod 420 .

[0041] It can be understood that, by threading the threaded rod 420 and the second pulley 401 , the threaded rod 420 can drive the driving gear 421 to extend downward or retract a specified length, thereby being suitable for slewing bearings of different heights.

[0042] It should be noted that the threaded rod 420 described in this embodiment is connected to the telescopic sleeve 411 via a bearing, and its rotational connection method is a common rotational connection method on the market, thereby ensuring the rotation of the threaded rod 420 and the driving gear 421.

[0043] In one embodiment of the present invention, Figure 1-Figure 3 As shown, the oil squeezing assembly 3 may include a reciprocating screw 30 , an oil squeezing plate 31 and an oil outlet pipe 32 .

[0045] It can be understood that, through the setting of the reciprocating screw 30, after the oil squeezing plate 31 squeezes the butter in the oil filling box 1 downwards, it can return to its original position upwards under the action of the reciprocating screw 30, thereby facilitating the addition of butter in the oil filling box 1 and the installation of the oil squeezing plate 31 after the addition is completed.

[0046] In one embodiment of the present invention, Figure 1-Figure 3 As shown, a trolley 5 may also be included, and the oil filling tank 1 is arranged on the trolley 5.

The motor 2 drives the reciprocating screw 30 to rotate, and drives the oil squeezing plate 31 to move downward to squeeze the butter, so that the butter in the oil filling box 1 enters the slewing bearing from the oil outlet pipe 32. At the same time, the motor 2 drives the first pulley 400 to rotate, the first pulley 400 drives the second pulley 401 through the transmission belt 402, and the second pulley 401 drives the threaded rod 420 and the driving gear 421 to rotate, so that the driving gear 421 meshes with the outer gear of the slewing bearing and rotates, thereby realizing the joint control rotation of the outer gear of the slewing bearing, reducing the labor intensity of the relevant personnel, and improving the oil filling efficiency of the slewing bearing.

[0049] In summary, the oil filling device for the slewing bearing in the embodiment of the utility model does not need to manually rotate the outer gear of the slewing bearing during oil filling, thereby reducing the labor intensity of related personnel and improving the oil filling efficiency of the slewing bearing.
