Description
Technical field
The utility model is specifically related to a kind of powder metallurgical gear with lubricating component.
Background technique
The advantage of powder metallurgical gear:
1, cost is low, and manufacturing efficiency is high, once-through, does not need to reprocess the gear teeth after shaping,
2, due to the processing characteristics of powder metallurgy, the part of oil-containing can be made, formed and exempt from lubricating detail, but effect be still weaker than bath lubrication, belongs to boundary lubrication condition,
3, do not have waste material in gear forming process, the utilization for iron and steel resource is best;
Two, the gear shortcoming of powder metallurgy:
1, because powder metallurgy is the recrystallization process allowing metallic dust at high temperature be formed, not through the operation of rolling, not forming steel fiber stream, is a kind of No yield point mechanical property, and therefore, the bending resistance of the gear teeth, shearing strength are all not so good as the gear of traditional machining
2 or because 1 reason, the tooth contact intensity of powder metallurgical gear is also lower, therefore can not transmitting large torque
Although 3 can make the gear teeth containing oil condition, glossy effective time limit is shorter, wants to ensure normal use, and still will consider additional lubrication, bath lubrication is best,
4, the precision comparison of powder metallurgical gear is low, because have no idea to control in the process that high temperature sintering is shaping, just want to bake bricks equally, what adobe burnt brick is actually, and its accurate dimension is all uncontrollable, and therefore, transmission stability is poor,
5, by 4 reason, the surface roughness of the gear teeth is also larger, can produce noise in transmission,
In sum, can consider with powder metallurgical gear in some unessential mechanisms, as toy etc., precision drive, Large-torsion transmisson etc. still want the gear of first-selected machining.
