Detailed Description
The utility model will be described in further detail with reference to the drawings and the detailed description.
As shown in fig. 3 and 6, the high-load gear includes a first gear 1 and a second gear 2. As shown in fig. 1 and 4, through holes 8 for installing transmission shafts in a matching manner are formed in the centers of the first wheel disc 3 of the first gear 1 and the second wheel disc 4 of the second gear 2. For ease of installation, the shape of the through holes 8 of the first and second discs 3, 4 should be consistent. The shape of the through hole 8 is: the hole wall of the circular through hole is provided with a key slot 9 matched with the transmission shaft.
As shown in fig. 1 and 4, oil holes 5 are formed in the tops of gear teeth 7 of the first gear 1 and the second gear 2, oil grooves 6 are formed in the first gear 1 and the second gear 2, and the oil grooves 6 are communicated with the oil holes 5. The manufacturing method of the oil groove 6 structure comprises the following steps: in the production process of the first gear 1 and the second gear 2, the first gear and the second gear are divided into two thinner gears, and annular groove bodies are formed in the thinner gears. And then welding the two thinner gears into a whole, and polishing the welded part until the shape of the gear teeth at the welded part is involute. A hole communicating with the oil groove 6 is bored at the tip of the gear tooth 7 as the oil hole 5.
The working principle is as follows: when the lubricating oil at the engagement position of a certain gear tooth 7 is extruded, the lubricating oil flows into the oil groove 6 along the oil hole 5, and the inside of the oil groove 6 is communicated. Due to the action of centrifugal force, the lubricating oil in the oil groove 6 flows out again along the oil hole 5, and further plays a role in lubricating the engaged gear teeth 7. The remaining lubricating oil can be stored in the oil groove 6, and thus the frequency of increase of the lubricating oil can be reduced. When the gaps of the gear teeth 7 contain impurities, the impurities can move due to the flowing of lubricating oil, and the impurities cannot cause pitting corrosion to the gear teeth 7 due to long-term adhesion to one point, so that the service life of the gear can be prolonged.
As shown in fig. 2 and 5, one end of the first wheel disc 3 is provided with a cylindrical protrusion 10 with a groove 11, one end of the second wheel disc 4 is provided with an L-shaped prism 13, and a side curved surface of the cylindrical protrusion 10 is provided with a groove 11 along a radial direction, which can be assembled with the L-shaped prism 13 through a mortise and tenon structure. The cylindrical bulge 10 is provided with a threaded through hole 12 along the axial direction, the wheel disc II 4 is also provided with a threaded through hole 12 along the axial direction, the sizes of the threaded through holes 12 of the wheel disc II and the wheel disc II are kept consistent, and the high-load gear is convenient to be structurally reinforced through the threaded through holes 12 and the fixing bolts, so that the strength of the high-load gear is enhanced.
The utility model discloses a high-bearing gear, which ensures that the gear is not easy to fail when bearing high load torque and has higher strength. In addition, the high-bearing gear is simple in structure, easy to process, convenient to produce in mass production and high in economical practicability.
