Abstract
The present invention provides a kind of finish forge curved tooth gear-boxes, belong to technical field of transmission machinery.It solves the problems, such as that existing gear can generate mesh impact during operation and noise corresponding with gear mesh frequency occurs.This finish forge curved tooth gear-box, realize the transmission shaft and be located at the intermeshing finish forge helical gear of end part of driving shaft that power is output and input respectively including cabinet, two, seal the long lid for being fixed with positioning two transmission shafts effect on cabinet respectively by screw rod and sealing ring, the outside port of long lid passes through oil sealing sealing, two roller bearings are coaxially arranged in long lid, bushing is provided on transmission shaft between its helical gear of input terminal and roller bearing and is arranged with circlip in outer end, its angle α is 68 degree between two transmission shafts.The present invention has the advantages that transmission is more steady to which noise be effectively reduced.
Description
Technical field
The invention belongs to technical field of transmission machinery, are related to a kind of gear-box, in particular to a kind of finish forge curved tooth gear-box.
Background technique
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 transmitting 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, the common household electrical appliances into daily life, clock and watch etc., application are 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, during operation can
It generates mesh impact and noise corresponding with gear mesh frequency occurs, make 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.
Summary of the invention
The purpose of the present invention is being directed to the above-mentioned problems in the prior art, provide a kind of transmission it is more steady to
The finish forge curved tooth gear-box of noise is effectively reduced.
Object of the invention can be realized by the following technical scheme: a kind of finish forge curved tooth gear-box, including cabinet, two points
The transmission shaft that outputs and inputs of power and the intermeshing finish forge helical gear of end part of driving shaft, the cabinet Shi Xian not be located at
Upper to seal the long lid for being fixed with positioning two transmission shafts effect respectively by screw rod and sealing ring, the outside port of the long lid is logical
Cross oil sealing sealing, which is characterized in that be coaxially arranged with two roller bearings in the long lid, be located on the transmission shaft defeated
Enter to hold and is provided with bushing between its helical gear and roller bearing and is arranged with circlip, two transmission shafts in outer end
Between its angle α be 68 degree.
The technical effect of this finish forge curved tooth gear-box are as follows: support fixed shafting by being connected long lid on the cabinet of gear-box
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 generates when more steadily reducing gear-box operation that makes the transmitting of power.
In a kind of above-mentioned finish forge curved tooth gear-box, sealed set has access cover on the cabinet.Pass through maintenance door
It can be convenient the engagement situation for checking box house helical gear, and fill lubricating oil into cabinet.
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 to link up air-flow inside and outside cabinet, the intracorporal air pressure of case will not the oil temperature when gear-box operates increase due to increase
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 which the excellent of noise be effectively reduced
Point.

There is the long lid 4 of positioning two transmission shafts 2 effect, the outside port of long lid 4 is sealed by oil sealing 5, is coaxially arranged in long lid 4
Two roller bearings 6 are provided with bushing 7 between its helical gear 3 of input terminal and roller bearing 6 on transmission shaft 2 and in outer end
Portion is arranged with circlip 8, its angle α is 68 degree between two transmission shafts 2.
It further describes in detail, checks the engagement situation of 1 internal helicoid gear 3 of cabinet for convenience, and fill profit into cabinet 1
Lubricating oil, sealed set has access cover 9 on cabinet 1.
In order to link up the air-flow inside and outside cabinet 1, air pressure in cabinet 1 will not the oil temperature when gear-box operates increase due to increase
