Problems solved by technology

Because the powdery fine particles in the crushing chamber will be adsorbed to the oil seal assembly, after a period of time, the powdery fine particles will break through the felt and oil seal of the oil seal assembly with the rotation of the main shaft and enter the bearing, resulting in heat generation and wear failure of the oil seal

Embodiment Construction

[0014] Such as figure 2 As shown, a shredder oil seal assembly includes a felt 2 and an oil seal 3 , and the oil seal 3 is mounted on the felt 2 in reverse. The oil seal 3 is in the shape of a ring. One end of the oil seal 3 has a spring 4 . The spring end of the oil seal 3 is installed near the felt 2.

[0015] After assembling the spring end of the oil seal 3 of the oil seal assembly 1 at the end 6 of the crushing chamber, the powdery fine particles rotate with the main shaft 8 and break through the lip of the end of the oil seal 3 with spring to effectively block it, preventing or delaying its entry into the bearing 9. The 3 secondary lips of the oil seal will also effectively prevent the high-temperature lithium-based grease from easily leaking, which can ensure the normal use of the bearing 9.

[0016] The foregoing embodiment is only an example of the present invention, and is not intended to limit the implementation and scope of rights of the present invention. All ...

Abstract

The invention discloses a grinder oil seal assembly which comprises felts and annular oil seals. The oil seals are reversely mounted on the felts, one end of each oil seal is provided with a spring, and the end with the spring of each oil seal is mounted at a position close to the corresponding felt. After the ends with the springs of the oil seals of the oil seal assembly are assembled at a grinding chamber end, powdery small granular materials rotate along with a spindle, break through the oil seals, can be effectively stopped by lips at the ends with the springs of the oil seals and are prevented or delayed to enter bearings, easy leakage of lithium-based grease can be effectively prevented by auxiliary lips of the oil seals, and normal use of the bearings can be ensured.

Description

technical field [0001] The invention relates to the technical field of sealing equipment, in particular to a pulverizer oil seal assembly. Background technique [0002] When feed and similar materials are pulverized by the pulverizer, the oil seal assembly is required to prevent the grease from lubricating the bearing from leaking, and to prevent the material and dust from entering the bearing. Because the powdery fine particles in the crushing chamber will be adsorbed to the oil seal assembly, after a period of time, the powdery fine particles will break through the felt and oil seal of the oil seal assembly with the rotation of the main shaft and enter the bearing, causing the oil seal to heat up and wear out. The oil seal assembly before improvement (such as figure 1 As shown) the end of the oil seal with spring is assembled at the bearing end. Because the bearing is lubricated with high-temperature lithium-based grease, the grease is not easy to leak from the oil seal a...
