Description

Technical Field

[0001] The utility model belongs to the technical field of transmission components and relates to a transmission, in particular to a transmission housing. Background Art

[0002] The transmission, also known as the gearbox, is a mechanism used to change the speed and torque from the engine. It can fix or change the transmission ratio of the output shaft and the input shaft in stages to meet the different requirements of the operating speed or traction of machines such as machine tools, automobiles, and tractors. The transmission housing, also known as the gearbox housing, is a key component of the automotive transmission system. It acts as a protective shell to protect the gears, shafts, and other components inside from dust, debris, water, and other contaminants.

[0003] When installing a conventional transmission case, lubricating oil is added to lubricate the gears to prevent wear. Since the oil carries metal debris from the gears for lubrication, it can cause tooth surface wear and pitting, affecting the service life of the gears. Summary of the invention

[0004] The utility model aims to solve the above problems existing in the prior art and provides a transmission housing with multiple layers for filtering metal impurities.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a transmission housing, characterized in that it includes a housing body with an installation cavity, a plurality of slow-flow filter screens are provided on the inner wall of the installation cavity, a plurality of the slow-flow filter screens are provided with guide plates, and the slow-flow filter screens are provided with filter screens, the filter screens are set at an obtuse angle to the guide plates, and magnets are provided on the guide plates.

[0006] In the above-mentioned transmission housing, a plurality of clamping grooves for fixing the magnets are provided at the bottom of the installation cavity, and a fixing cavity for fixing the magnets is provided on the guide plate.

[0007] In the above transmission housing, a plurality of guide columns are arranged on the top of the magnet, a plurality of filter holes are opened on the filter screen, and the guide columns and the filter holes are arranged at intervals.

[0008] In the above-mentioned transmission housing, an oil filling hole and an observation hole are provided on the housing body, and the observation hole is provided with tempered glass.

[0009] In the above-mentioned transmission housing, a drainage angle is provided on one side of the magnet, and a transition fillet is provided on the top of the guide column.

[0010] Compared with the prior art, the transmission housing of this invention slows down the flow rate of the lubricating oil by arranging a slow-flow filter in the mounting cavity, filters out metal debris in the oil, and reduces the wear of the inner wall parts. At the same time, the magnet can absorb metal mud in the lubricating oil to further purify the lubricating oil. The observation window can observe the practical condition of the filter screen, which is convenient for maintenance of the transmission. BRIEF DESCRIPTION OF THE DRAWINGS
