Description
Technical field
The utility model belongs to technical field of transmission machinery, is related to a kind of gear-box, more particularly to a kind of finish forge curved tooth tooth
Roller box.
Background technology
Gear-box is a kind of power transfer mechanism, the revolution of motor can be transformed into the revolution of needs, and can change
Torque, in the mechanism currently used for passing power and movement, the application range of gear-box is quite extensive, almost in various machinery
Transmission in can see its trace, from the ship, automobile, locomotive of the vehicles, heavy-duty machinery for building, mechanic
Processing machine used in industry and automated production equipment, to household electrical appliances common in daily life, clock and watch etc., application is moved from big
Smaller load is arrived in the transmission work of power, and accurate angle transmission can see the application of gear-box, therefore be widely used in speed
With the conversion equipment of torque.The bearing capacity and stable drive performance of gear with curved teeth are significantly better than spur gear, can meet height well
Fast heavy load transmission requires a pair of of gear engagement, due to being inevitably present tooth pitch, tooth form equal error, the meeting in operation process
It generates mesh impact and noise corresponding with gear mesh frequency occurs, made an uproar between the flank of tooth since friction also occurs for opposite sliding
Sound.Since gear is the fundamental parts in gearbox drive, it is very necessary to control Gear-box Noise to reduce grating of gears.
Invention content
The purpose of this utility model is to be directed to the above-mentioned problems in the prior art, and it is more steady to provide a kind of transmission
To effectively reduce the finish forge curved tooth gear-box of noise.
The purpose of this utility model can be realized by following technical proposal：A kind of finish forge curved tooth gear-box, including babinet,
Two realize the transmission shaft that power is output and input and are located at the intermeshing finish forge helical gear of end part of driving shaft respectively, described
Seal the long lid for being fixed with positioning two transmission shafts effect, the outer end of the long lid on babinet respectively by screw rod and sealing ring
Mouth passes through oil sealing sealing, which is characterized in that is coaxially arranged with two roller bearings in the long lid, the transmission shaft is upper
It is provided with bushing between its helical gear of input terminal and roller bearing and is arranged with circlip, two biographies in outer end
Its angle α is 68 degree between moving axis.
The technique effect of this finish forge curved tooth gear-box is：On the babinet of gear-box fixed shafting is supported by being connected long lid
Part transmission shaft and helical gear, and ensure that drive shaft axis mutual alignment by the way that two roller bearings are respectively set in long lid
Accuracy, the noise that the generates when transmission of power being made more steadily to reduce gear-box operation.
In a kind of above-mentioned finish forge curved tooth gear-box, sealed set has access cover on the babinet.Pass through maintenance door
The engagement situation for checking box house helical gear can be facilitated, and fill lubricating oil into babinet.
In a kind of above-mentioned finish forge curved tooth gear-box, the length positioned at input terminal, which covers, offers gas vent.Exhaust
The setting in hole is used for linking up air-flow inside and outside babinet, and the oil temperature raising due to that the air pressure in babinet will not be when gear-box operate increases
Greatly, and the sealing performance of its contact surface is improved.
In a kind of above-mentioned finish forge curved tooth gear-box, the speed ratio of the gear-box is 1: 1, modulus 4.233, and the number of teeth is
19。
Compared with prior art, this finish forge curved tooth gear-box has transmission more steady to effectively reduce the excellent of noise
Point.
