Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of engineering machinery, and in particular relates to a grease lubrication system for a double-swing motor of an excavator. Background Art
[0002] The dual-slewing motor excavator uses two slewing motors to achieve 360° rotation of the upper vehicle system relative to the lower vehicle system, so as to achieve operation within a 360° range. The slewing motor drives the slewing device to rotate. During the entire operation cycle of the excavator, the movement frequency of the slewing motor is high, and the internal bearings and other parts also rotate accordingly. In order to reduce friction, the bearings and other parts inside the slewing motor reducer are lubricated with butter.
[0003] In the prior art, the grease filling requires the operator to operate on the upper frame of the excavator, and the grease is filled through the filling port on the rotary motor. When the grease is full, grease will overflow from the oil outlet. However, since the rotary motor is assembled on the upper frame of the excavator and is surrounded by components such as the main valve and hose, the operator needs to enter the upper frame to perform the grease filling operation. The filling is very inconvenient due to the small space, and the oil outlet is on the other side of the grease filling port. When the grease is full, it cannot be discovered in time, resulting in a large amount of grease overflowing and accumulating at the oil outlet, polluting the upper frame and causing grease waste. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a grease lubrication system for a double-swing motor of an excavator.
[0005] In order to achieve the above purpose, the utility model is implemented by adopting the following technical solutions:
[0006] A grease lubrication system for dual rotary motors of an excavator comprises a first rotary motor, a second rotary motor and an oil circuit block, wherein the first rotary motor is connected to the oil circuit block via a first oil inlet pipe and a first oil outlet pipe, and the second rotary motor is connected to the oil circuit block via a second oil inlet pipe and a second oil outlet pipe, and a grease nipple for filling grease is provided on the oil circuit block.
[0007] Preferably, the oil circuit block is provided with grease nipple a1, grease nipple b1, grease nipple a2 and grease nipple b2, grease nipple a1 is connected to the first oil inlet pipe through an oil circuit channel provided inside the oil circuit block, grease nipple b1 is connected to the first oil outlet pipe through an oil circuit channel provided inside the oil circuit block, grease nipple a2 is connected to the second oil inlet pipe through an oil circuit channel provided inside the oil circuit block, and grease nipple b2 is connected to the second oil outlet pipe through an oil circuit channel provided inside the oil circuit block.
[0008] Preferably, the first oil inlet pipe and the first oil outlet pipe are connected to the first rotary motor through a first joint respectively.
[0009] Preferably, the second oil inlet pipe and the second oil outlet pipe are respectively connected to the second rotary motor through a second joint.
[0010] Preferably, the first oil inlet pipe, the first oil outlet pipe, the second oil inlet pipe and the second oil outlet pipe are all mounted on the upper frame by means of pipe clamps and screws.
[0011] Preferably, the oil circuit block is installed at the bottom of the front end panel of the upper frame.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. The oil nozzles of the first oil inlet pipe, the first oil outlet pipe, the second oil inlet pipe and the second oil outlet pipe are integrated on the oil block. The oil block is arranged at the bottom of the front panel of the upper frame. The operator can directly add grease to the double-swing motor of the excavator on the ground, which improves work efficiency;
[0014] 2. The four grease nozzles on the oil block are used to add grease and discharge grease respectively, which can clearly determine whether the grease is full. After the grease is full, feedback will be given. Through the system feedback, the operator can know it at the first time, which greatly improves the convenience of grease filling and saves maintenance time;
[0015] 3. The utility model fills grease through the oil circuit block, and delivers it to the second rotary motor and the first rotary motor through the second oil inlet pipe and the first oil inlet pipe. After the grease is filled, it is fed back to the oil circuit block through the second oil outlet pipe and the first oil outlet pipe. The lubrication system is composed of two independent parts, each of which serves a rotary motor independently without affecting each other. It is convenient to add grease during ground operation and give timely feedback after the grease is full. It can be found in time that the grease is full, thus avoiding the situation of large amount of grease overflowing and accumulating to pollute the frame. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0022] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings.
[0023] Embodiment 1:
[0024] like Figure 1-3 As shown, a grease lubrication system for a dual-swing motor of an excavator comprises a first swing motor 1, a second swing motor 2 and an oil circuit block 7. The first swing motor 1 is connected to the oil circuit block 7 via a first oil inlet pipe 5 and a first oil outlet pipe 6, and the second swing motor 2 is connected to the oil circuit block 7 via a second oil inlet pipe 3 and a second oil outlet pipe 4. A grease nipple 8 for filling grease is provided on the oil circuit block 7. Grease is filled via the grease nipple 8, which facilitates ground filling and improves work efficiency.
[0025] Embodiment 2:
[0026] A grease lubrication system for a double-swing motor of an excavator, which is different from the first embodiment in that Figure 4 As shown, the oil circuit block 7 is provided with grease nipple a1, grease nipple b1, grease nipple a2 and grease nipple b2. The grease nipple a1 is connected to the first oil inlet pipe 5 through an oil circuit channel provided inside the oil circuit block 7, the grease nipple b1 is connected to the first oil outlet pipe 6 through an oil circuit channel provided inside the oil circuit block 7, the grease nipple a2 is connected to the second oil inlet pipe 3 through an oil circuit channel provided inside the oil circuit block 7, and the grease nipple b2 is connected to the second oil outlet pipe 4 through an oil circuit channel provided inside the oil circuit block 7.
[0027] In this embodiment, by integrating grease nipple a1, grease nipple b1, grease nipple a2 and grease nipple b2 on the oil circuit block 7, the oil circuit block 7 is arranged at the bottom of the front end panel of the upper frame 10. The operator can directly add grease to the first rotary motor 1 and the second rotary motor 2 of the excavator on the ground, thereby improving work efficiency.
[0028] Furthermore, the first oil inlet pipe 5 and the first oil outlet pipe 6 are connected to the first rotary motor 1 through the first joint 13 , respectively; the second oil inlet pipe 3 and the second oil outlet pipe 4 are connected to the second rotary motor 2 through the second joint 9 , respectively.
[0029] like Figure 5 As shown, the first oil inlet pipe 5 , the first oil outlet pipe 6 , the second oil inlet pipe 3 and the second oil outlet pipe 4 are all installed on the upper frame 10 through pipe clamps 11 and screws 12 ; the oil block 7 is installed at the bottom of the front end panel of the upper frame 10 .
[0030] The working principle of the utility model is:
[0031] 1) Fill the first rotary motor 1 with butter:
[0032] Aim the grease gun at the grease nipple a1 on the oil circuit block 7 to add grease. The grease will be transmitted to the first rotary motor 1 through the first oil inlet pipe 5. After the grease is full, the excess grease will overflow to the grease nipple b1 on the oil circuit block 7 through the first oil outlet pipe 6. When grease overflows from the grease nipple b1, it proves that the grease is full, then stop adding grease.
[0033] 2) Fill the second rotary motor 2 with butter:
[0034] Aim the grease gun at the grease nipple a2 on the oil circuit block 7 to add grease. The grease will be transmitted to the second rotary motor 2 through the second oil inlet pipe 3. After the grease is full, the excess grease will overflow to the grease nipple b2 on the oil circuit block 7 through the second oil outlet pipe 4. When butter overflows from the grease nipple b2, it proves that the grease is full, then stop adding grease.
[0035] Therefore, the utility model adds butter through the oil circuit block 7, and transports it to the second rotary motor 2 and the first rotary motor 1 through the second oil inlet pipe 3 and the first oil inlet pipe 5. After the butter is filled, it is fed back to the oil circuit block 7 through the second oil outlet pipe 4 and the first oil outlet pipe 6. Its lubrication system consists of two independent parts, each of which serves a rotary motor independently without affecting each other. It is convenient to add butter during ground operation and give timely feedback after the butter is full, which greatly improves the convenience of butter filling, saves maintenance time, and can promptly detect that the butter is full, avoiding a large amount of butter overflowing and accumulating to contaminate the upper frame 10.
