Abstract
The utility model relates to a transmission gear of an engine oil pump. The transmission gear of an engine oil pump of the utility model comprises a gear shaft and a tooth ring, wherein a plurality of wheel teeth are distributed on the tooth ring along a circumference, the wheel teeth which are twisted slantwise are distributed along the circumference to form a helical structure and four sides of the tooth surface of the wheel teeth are provided with chamfers. The transmission gear of an engine oil pump of the utility model has the advantages of small processing difficulty, short technology periods, stable quality, high utilization ratio of material, high transmission stability and high abrasive resistance, therefore the service life of the engine oil pump is extended.
Description
Technical field
The utility model relates to a kind of oil pump transmission part, specifically is a kind of oil pump driving gear.
Background technique
Oil pump is the accessory commonly used that is used for motor car engine.The structural type of oil pump has usually: gear type, Dusai type and rotator type.Wherein, gear type oil pump reliable operation and durable is so use wider.Gear type oil pump is fixed on the cylinder block, is driven the spiral gear on the oil pump and is driven by the spiral gear on the camshaft.
Gear part is when work, because transmitting torque, tooth root bears bigger flexural stress, and tooth surface bears bigger contact stress, and bears strong friction and wear, and startup or the meshing bad gear that will make are impacted.Therefore, gear part has higher performance requirement: (1) has high hardness and wear resistance; (2) flank of tooth has high contact fatigue strength, and tooth root has high flexural strength; (3) heart degree (each tooth) will have enough intensity and toughness.
Summary of the invention
The purpose of this utility model is to provide a kind of oil pump driving gear, meets modern requirement to gear part, can prolong the working life of oil pump, guarantees the normal operation of motor.
Oil pump driving gear described in the utility model comprises gear shaft and gear ring, some gear teeth circumferentially on the gear ring, and the described gear teeth are the oblique gear teeth that reverse, and circumferentially form helicoidal structure; The four edges of the flank of tooth of the described gear teeth has chamfering.
The chamfer angle of the described flank of tooth is in 15 degree.
The chamfering width of the described flank of tooth is between 1-2mm.
Compare with existing oil pump gear, the difficulty of processing of oil pump driving gear described in the utility model is little, and process cycle is short, steady quality, and the stock utilization height, the transmission stability height, the wear resistance height, thus prolonged the working life of oil pump.
