Product Description

High density tungsten alloy crankshaft counterweight block:

Xi'an Kefefeng Powder Metallurgy Co., Ltd is a manufacturer, mian produce Tungsten Based High Density alloy products:
Below is our products tungsten alloy carkshaft counterweight used in engine.
The high density tungsten alloy crankshaft counterweight is an important component on the engine. Its function is to convert the up and down motion of the piston into circular motion on the crankshaft, which is connected to the flywheel to reduce the vibration of a four stroke engine. A shock absorber will also be installed on the other end of the crankshaft, which can weaken the torsional vibration generated by the crankshaft at the output end of the cylinder. The tungsten based high density tungsten alloy crankshaft counterweight block has a special shape, and its function is to reduce the turbulence of the crankshaft. The quality and position of the tungsten alloy crankshaft counterweight are determined by the engine cylinder, engine structure, and engine ignition sequence. The tungsten alloy crankshaft counterweight can balance dynamic loads, and the tungsten alloy crankshaft counterweight can change the tension of the crankshaft. Tungsten alloy crankshaft counterweights can also be used to reduce the radial load on bearings.
The crankshaft of racing engines: using high density tungsten alloy crankshaft counterweights can reduce the radial clearance of the crankshaft
High density tungsten alloy crankshafts can be divided into two categories: tungsten alloy counterweight crankshafts and tungsten alloy power crankshafts
The high density tungsten alloy counterweight crankshaft is used to balance the rotational inertia force and torque generated by the connecting rod big end, connecting rod journal, and crankshaft, making the engine crankshaft run smoothly. Some counterweight crankshafts are integrated with the crankshaft as an extension, while others are individually made into parts and fixed to the crankshaft with bolts.
The high density tungsten alloy power crankshaft is connected to the piston, which converts the up and down (reciprocating) motion of the connecting rod into cyclic (rotating) motion to achieve power transmission of the crankshaft.
