Detailed Description
The present application is described in further detail below with reference to figures 1-2.
The embodiment of the application discloses an oil thrower.
Referring to fig. 1 and 2, the oil thrower comprises an oil thrower body 1, and the thickness of the oil thrower body 1 is 0.5cm-1 cm. Since the space between the oil tank and the wall is small, generally only 2cm, the thin oil thrower body 1 is easy to install.
Wherein, the central point of the oil thrower body 1 is provided with a through hole 3 for the shaft of the air blower to pass through, an opening 4 is arranged on the oil thrower 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 part 8 for fixing the oil thrower body 1 and a fan shaft is arranged on the oil thrower body 1 and at the opening 4. Wherein the fixing member 8 includes fixing pieces 7, the fixing pieces 7 are provided in two and located at both sides of the opening 4, respectively, and each fixing piece 7 is provided with a bolt hole 5 for mounting a bolt.
Through hole 3 with the suit of disc main part 1 on the fan axle, because the setting of opening 4 for the internal diameter of through hole 3 is a bit bigger than the external diameter of fan axle, the installation of the disc main part 1 of being convenient for. After the oil thrower body 1 is sleeved on the fan shaft, the two fixing pieces 7 are fixed through bolts, and at the moment, the oil thrower body 1 is firmly fixed on the fan shaft under the extrusion action of external force. Based on the structure of disc main part 1, construction bolt fixes on disc main part 1, need not additionally to install locking device in the next door of disc to be convenient for disc main part 1's installation, and effectively solve the narrow and small problem that leads to the disc installation difficulty in oil tank inner space.
The fixing piece 7 is formed by extending the oil thrower body 1 outward, that is, the fixing piece 7 and the oil thrower body 1 are integrally formed, so that the fixing piece 7 and the oil thrower body 1 are connected more firmly, the reduction of the production process of the oil thrower body 1 is facilitated, and the production efficiency is improved.
The oil slinger body 1 is also provided with a groove 6, and the groove 6 is communicated with the through hole 3 and is arranged on the opposite side of the opening 4. When the installation disc, behind 4 positions through the bolt-up opening, can make disc main part 1 appear bending deformation, be provided with recess 6 in order to let this place crooked, let disc main part 1 paste tight fan axle more, reach the tight fixed effect of expanding to it is epaxial to make the more even fan that contacts of disc main part 1, the atress also can be more even, can play increase of service life's effect.
In addition, a balance block 9 is arranged on the outer side wall of the oil thrower body 1 and at the position opposite to the opening 4, so that the balance block 9 corresponds to the fixing piece 7, and the oil thrower body 1 is more stable when rotating along with the fan shaft. Wherein, recess 6 sets up near balancing piece 9, because 1 width of oil slinger main part is less than the 9 width of balancing piece, sets up recess 6 in the other positions of oil slinger main part 1, can increase the fracture risk of oil slinger main part 1, and recess 6 sets up and can reduce the fracture risk of oil slinger main part 1 near balancing piece 9, increases the life of oil slinger.
The oil thrower main body 1 outwards extends and has two long and narrow assembling pieces 2, and the assembling pieces 2 are distributed in an opposite mode and are arranged on a vertical line of the opening 4 and the groove 6, so that the resistance when the oil thrower main body 1 rotates is effectively reduced, the power loss of the fan is reduced, and the fan is more energy-saving.
Because two assembly pieces 2, stationary blade 7 and balancing piece 9 are along the circumference evenly distributed of 1 lateral wall of oil slinger main part for oil slinger main part 1 is more stable when following the rotation of fan axle. In addition, the thickness of the fitting piece 2 is smaller than that of the oil slinger body 1, so that the resistance when the oil slinger body 1 rotates is further reduced, and the reduction of the production cost is facilitated.
The implementation principle of this application embodiment's oil thrower does: before the fan is used, the oil thrower is sleeved on the fan shaft from the port of the fan shaft, the two fixing pieces 7 are pressed and fixed together by using bolts, and the oil thrower is fastened on the fan shaft. When the fan shaft rotates, the oil thrower is driven to rotate, the assembly pieces 2 on the oil thrower stir lubricating oil below the oil tank and throw the lubricating oil, and the lubricating oil is thrown onto two disc bearings of a wall body along the long and narrow assembly pieces 2 to lubricate the bearings.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
