AI Technical Summary
The bearings at both ends of the input shaft in existing mud pumps lack a lubrication system, which makes the bearings prone to damage.
A lubrication system for the input shaft of a mud pump was designed, including an oil sump, an oil pump, a connector, an overflow valve, and an oil nozzle. The oil pump supplies lubricating oil, and the oil nozzle sprays the lubricating oil directly onto the bearing mounting part to form a lubricating oil film. The oil pressure is controlled by the overflow valve to achieve the recycling of the lubricating oil.
Effective lubrication of bearings prevents overheating damage, extends bearing life, and ensures stable system operation by recycling lubricating oil, preventing leakage or seal damage caused by excessive oil pressure.

[0035] As shown in Figs. 1-3 A mud pump input shaft lubrication system, comprising
[0036] A mud pump body 1, an oil pool 11 is formed at the bottom of the pump body 1, an input shaft 3 and a crankshaft 4 are arranged at the upper end of the pump body 1, a gear transmission cooperation is formed between the input shaft 3 and the crankshaft 4, and the input shaft 3 and the crankshaft 4 are both located above the oil pool 11;
[0037] An oil pump 2, which is arranged in the oil pool 11;
[0038] A joint seat 21, which is arranged on the pump body 1, a distribution cavity is formed in the joint seat 21, the joint seat 21 is connected with an oil inlet pipe and a plurality of oil outlet pipes, and the oil inlet pipe is connected with the oil pump 2;
[0039] A plurality of oil nozzles 53, each oil nozzle 53 is connected with an oil outlet pipe, the oil nozzle 53 is fixed on the pump body 1, and the oil outlet of the oil nozzle 53 faces the bearing mounting portion of the input shaft 3.
[0040] Specifically, as an optional embodiment in the present embodiment, as shown in Fig. 1 The joint base 21 is connected with an overflow valve 22, which is located above the oil pool 11. When the lubricating oil pressure exceeds a set value, the overflow valve 22 is opened, and the excess lubricating oil in the joint base 21 flows back to the oil pool 11.
[0041] Specifically, as an optional embodiment in the present embodiment, as shown in Figs. 1-3 The pump body 1 is provided with bearing bases 5 at both ends, and the input shaft 3 is matched with the bearing bases 5 at both ends.
[0042] The oil nozzle 53 is arranged on the bearing base 5.
[0043] Specifically, as an optional embodiment in the present embodiment, as shown in Figs. 1-3 The inner side surface of the bearing base 5 is provided with a mounting ring 51, which is fixed on the bearing base 5 by bolts.
[0044] The oil nozzle 53 is fixed on the mounting ring 51 by screws.
[0045] Specifically, as an optional embodiment in the present embodiment, as shown in Fig. 2 and Fig. 3 The inner side of the mounting ring 51 is provided with an oil baffle 52 below, and the upper end of the oil baffle 52 is lower than the input shaft 3.
[0046] The inner side of the oil baffle 52 and the inner cavity of the bearing base 5 form an oil storage groove.
[0047] The oil storage groove is a part of the bottom of the inner cavity of the bearing base 5. The lubricating oil on the input shaft 3 can drip into the oil storage groove through the bearing. When the lubricating oil in the oil storage groove is full, it will overflow. The overflowed lubricating oil enters the oil pool 11 again, and after sedimentation and heat dissipation, it is sucked into the lubricating oil pump 2 again for the next cycle of lubrication, so as to realize the recycling of the lubricating oil and ensure the continuous and stable operation of the lubricating system.
[0048] In the present embodiment, a pressure gauge 23 is arranged on the oil outlet pipe. Through the pressure gauge 23, the oil pressure in the oil outlet pipe circuit can be known in real time.
[0049] The bearing bases 5 at both ends of the output shaft are respectively provided with an oil nozzle 53, and a plurality of oil nozzles 53 are also arranged on the crankshaft 4.

[0051] The working principle of the lubricating system of the input shaft of the mud pump is as follows: the oil pump 2 is the power source of the whole lubricating system, and starts to work after the mud pump is started, the oil pump 2 sucks lubricating oil, and after pressurization of the pump body 1, the lubricating oil has a certain pressure and flow, so as to be smoothly delivered to each part needing lubrication.
[0052] The lubricating oil discharged from the oil pump 2 first passes through the filter, and the filtered lubricating oil enters the joint seat 21, and the joint seat 21 plays a role of connecting and distributing the lubricating oil. It delivers the lubricating oil to the oil nozzles 53 on both sides of the input shaft 3, and after the lubricating oil forms a lubricating oil film at the bearing and other parts of the input shaft 3, the lubricating oil will take away the heat generated in the bearing during operation, play a role of cooling and cooling, and prevent the bearing from being damaged due to overheating. With the continuous operation of the input shaft 3, the lubricating oil will continuously circulate. Part of the lubricating oil will form a dynamic oil film between the rolling body and the inner and outer rings of the bearing, reducing friction and wear.
[0053] The overflow valve 22 is installed on the joint seat 21, and when the oil pressure in the lubricating system exceeds the set value, the overflow valve 22 will automatically open, and the excess lubricating oil will flow back to the oil pool 11, so that the oil pressure in the lubricating system is always kept within the normal range, preventing problems such as oil pipe rupture, seal damage or bearing overload due to excessive oil pressure, effectively protecting the normal operation of the whole lubricating system and the mud pump.
