Reference numerals illustrate: 1. an oil slinger body; 2. the assembly sheet 3, the through holes 4 and the openings; 5. bolt holes; 6. a groove; 7. a fixing piece; 8. a fixing member; 9. and a balance weight.
Detailed Description
The application is described in further detail below with reference to fig. 1-2.
The embodiment of the application discloses an oil thrower.
Referring to FIGS. 1 and 2, comprising a disc body 1, the disc body 1 has a thickness of 0.5cm to 1cm. Because the space between the oil tank and the wall is smaller, generally only 2cm is needed, and the disc-shaped oil slinger main body 1 is convenient to install.
Wherein, the central point of the oil slinger body 1 is provided with a through hole 3 for a fan shaft to pass through, an opening 4 is arranged on the oil slinger body 1 and on the outer side wall in a penetrating way, and the opening 4 is communicated with the through hole 3. A fixing piece 8 for fixing the oil slinger body 1 and a fan shaft is arranged on the oil slinger body 1 and positioned at the opening 4. Wherein the fixing piece 8 comprises fixing pieces 7, the fixing pieces 7 are provided with two fixing pieces and are respectively positioned at two sides of the opening 4, and each fixing piece 7 is provided with a bolt hole 5 for installing a bolt.
The oil thrower body 1 is sleeved on the fan shaft through the through hole 3, and due to the arrangement of the opening 4, the inner diameter of the through hole 3 is slightly larger than the outer diameter of the fan shaft, so that the oil thrower body 1 is convenient to install. After the oil slinger main body 1 is sleeved on the shaft of the fan, the two fixing plates 7 are fixed through bolts, and at the moment, the oil slinger main body 1 is firmly fixed on the shaft of the fan under the extrusion action of external force. Based on the structure of the oil thrower body 1, the installation bolts are fixed on the oil thrower body 1, and a locking device is not required to be additionally installed beside the oil thrower, so that the installation of the oil thrower body 1 is facilitated, and the problem that the oil thrower is difficult to install due to the narrow space in an oil tank is effectively solved.
It should be noted that, this stationary blade 7 is outwards extended by the disc body 1 and forms, and stationary blade 7 and disc body 1 integrated into one piece promptly makes stationary blade 7 and disc body 1 connect more firmly, and helps reducing disc body 1's production process, improves production efficiency.
The disc body 1 is further provided with a recess 6, which recess 6 communicates with the through-going opening 3 and is arranged on the opposite side of the opening 4. When the oil thrower is installed, after the position of the opening 4 is fastened through the bolts, bending deformation of the oil thrower body 1 can be caused, the groove 6 is arranged for bending the oil thrower body 1 to be more tightly attached to a fan shaft, the effect of expanding and fastening is achieved, the oil thrower body 1 is enabled to be more uniformly contacted with the fan shaft, the stress is also more uniform, and the effect of prolonging the service life can be achieved.
In addition, the balance weight 9 is arranged on the outer side wall of the oil slinger body 1 and positioned at the opposite position of the opening 4, so that the balance weight 9 corresponds to the fixing piece 7, and the oil slinger body 1 is more stable when rotating along with the fan shaft. Wherein, recess 6 sets up near balancing piece 9, because the width of disc body 1 is less than balancing piece 9 width, sets up recess 6 in other positions of disc body 1, can increase disc body 1 fracture risk, and recess 6 sets up near balancing piece 9 can reduce disc body 1 fracture risk, increases disc life.
The oil thrower body 1 outwards extends to have two long and narrow assembly pieces 2, and assembly pieces 2 are the opposite type and distribute to set up on opening 4 and recess 6's perpendicular line, effectively reduce the resistance when oil thrower body 1 rotates, thereby reduce fan pivoted power loss, make the fan more energy-conserving.
Because the two assembly pieces 2, the fixing piece 7 and the balance weight 9 are uniformly distributed along the circumference of the outer side wall of the oil slinger body 1, the oil slinger body 1 is more stable when rotating along with a fan shaft. In addition, the thickness of the assembly sheet 2 is smaller than that of the oil slinger body 1, so that the resistance of the oil slinger body 1 during rotation is further reduced, and meanwhile, the production cost is reduced.
The implementation principle of the oil thrower of the embodiment of the application is as follows: before the fan is used, the oil thrower is sleeved on the fan shaft from the port of the fan shaft, and the two fixing sheets 7 are pressed and fixed together by using bolts, so that the oil thrower is fastened on the fan shaft. When the fan shaft rotates, the oil thrower is driven to rotate, the assembly sheet 2 on the oil thrower stirs lubricating oil below the oil tank and throws the lubricating oil, and the lubricating oil throws the two-disc bearings of the wall body along the long and narrow assembly sheet 2 to play a role in lubricating the bearings.
The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
