Problems solved by technology
This utility model overcomes the shortcoming that the oil volume of the built-in oil pump is too low or too high when the speed is too low or too high, but the disadvantage is that the use of an additional power source makes the entire unit redundant and complicated
[0004] Patent CN 208595214 U relates to a vertical reducer, which has a set of oil injection mechanism built in, but this set of oil injection lubrication mechanism requires the transmission to have an upper and lower cavity structure, and a certain degree of sealing must be guaranteed. The versatility of the mechanism is not strong, and the speed cannot be adjusted

Embodiment Construction
[0017] Such as figure 1 with figure 2 As shown in the two-stage reducer device, the present invention is installed, and the input shaft 2 and the two-stage reducer power input shaft 0 in the present invention are correctly assembled using the rotary joint 1 to ensure oil transmission and Follow-up control. The output shaft section of the planet carrier 12 and the gear pump 16 are mechanically connected by the coupling 15. The shell 14 is fixed on the base of the work site.
[0018] In order to ensure that the mechanical equipment can be fully lubricated when starting and running smoothly, different gear ratios need to be allocated to each gear to ensure that the input speed of the gear pump reaches the rated speed. The following table is a table of the number of teeth and transmission ratio of the gear of the present invention.

The invention discloses a three-speed gear pump power unit for lubricating a gear box. The three-speed gear pump power unit for lubricating the gear box is characterized in that an original input power of the gear box is used, and a transmission mode of a three clutch-planet set is used for meeting the oil injection lubrication of the gear box under the condition of different rotating speeds of mechanical equipment. According to the three-speed gear pump power unit for lubricating the gear box, the defect that a gear pump cannot absorb lubricating oil and then cannot spray due to the fact thatthe rotating speed of the gear pump does not meet the requirement of normal operation in a traditional design is avoided, and oil injection lubrication can be carried out in the normal operation stage of the mechanical equipment.
Description
Technical field [0001] The invention relates to the field of transmission lubrication, in particular to a three-speed gear pump power unit for gearbox lubrication. Background technique [0002] Gearbox is the most common component in mechanical transmission. The common lubrication method is oil lubrication, usually oil immersion lubrication and oil spray lubrication. Among them, oil immersion lubrication is more common, but oil immersion lubrication has insufficient lubrication; and the gear needs to be enlarged. The tank volume is used to store lubricating oil, thereby increasing the weight of the gear box. In addition, it is necessary to configure an oil dump tank, a breather and an oil gauge to replace and observe the oil. Various disadvantages make people pursue an external fuel tank, and the design of oil injection lubrication can better solve the shortcomings of the large tank; not only that, the oil injection lubrication has a good effect on high-speed mechanical equipment...
