Abstract
The invention relates to a countershaft support device of a twin countershaft helical gear transmission. The countershaft support device comprises a main box countershaft support bearing which is a ball bearing or cylinder roller bearing. The countershaft support device of the twin countershaft helical gear transmission provided by the invention has the advantages of simple installation process, low failure rate and low cost.
Description
Technical field
The invention belongs to mechanical field, relate to a kind of support device, relate in particular to a kind of pair of jack shaft helical teeth transmission countershaft support device.
Background technique
Growing with card technique emphatically, market counterweight card speed changer bearing capacity and the quality for example requirement of noise reduction are more and more higher.For the bearing capacity that further lifting heavily blocks speed changer, occurred progressively that bearing capacity is bigger, noise is lower, the better two jack shaft helical teeth speed changers of quality.Traditional concept is thought, there is axial force in the helical teeth speed changer in transmission process, so needing to adopt tapered roller bearing to carry out the jack shaft axle head supports, adopt the speed changer of helical gear type of belt drive can effectively reduce noise and impact, improve gear capacity, thereby promote the speed changer q﹠r greatly.Referring to Fig. 1 and Fig. 2, tapered roller bearing has all been adopted in the support of two jack shaft helical teeth speed changer major-minor case jack shafts that domestic and international well-known speed changer production company is produced.Yet owing to tapered roller bearing cost height, need to carry out gap adjustment during the course, installation procedure complexity, rate of fault height have seriously restricted the application and the development of two jack shaft helical teeth speed changers.
Summary of the invention
In order to solve the above-mentioned technical problem that exists in the background technique, the invention provides two jack shaft helical teeth transmission countershaft support devices that a kind of installation procedure is simple, rate of fault is low and with low cost.
Technical solution of the present invention is: the invention provides a kind of pair of jack shaft helical teeth transmission countershaft support device, comprise main tank jack shaft spring bearing, its special way is: described main tank jack shaft spring bearing is ball bearing or roller bearing.
Above-mentioned pair of jack shaft helical teeth transmission countershaft support device also comprises odd-side jack shaft spring bearing, and described odd-side jack shaft spring bearing is ball bearing or roller bearing.
Advantage of the present invention is:
The present invention is based on theoretical calculation (axial force that transmission is produced to the twin countershaft transmission helical gear is calculated), when calculating shows the helical gear transmission, carry out suitable helical gear parameter adjustment, can make two pairs of helical gear shafts on the same axis opposite to force direction, size is close; And traditional ball bearing and roller bearing all can satisfy usage requirement.So the present invention changes to ball bearing (or roller bearing) with the spring bearing at two jack shaft helical teeth speed changer major-minor case jack shafts two ends by traditional tapered roller bearing, this invention has fundamentally solved the influence to two jack shaft helical teeth speed changers of bearing cost, quality and assembly technology.Because carrying out not needing to carry out the bearing play in the speed changer assembly process at use ball bearing (or roller bearing) regulates, simplified the assembly technology of two jack shaft helical teeth speed changers to a certain extent, reduced the cost of helical teeth speed changer, for the popularization of two jack shaft helical teeth speed changers is laid a good foundation.

Embodiment
The present invention is replaced by ball bearing (or roller bearing) with the spring bearing at two jack shaft helical teeth speed changer helical teeth transmission jack shafts two ends by traditional tapered roller bearing.Because through theoretical calculation, two jack shaft helical teeth speed changers are in transmission process, the axial force direction that major-minor case jack shaft two ends are produced is opposite, and size is close, and the sizes of balls bearing (or roller bearing) of this axial force can bear.Stand test shows that the present invention can satisfy the speed changer usage requirement.Because carrying out not needing to carry out the bearing play in the speed changer assembly process at use ball bearing (or roller bearing) regulates, simplified the assembly technology of two jack shaft helical teeth speed changers to a certain extent, reduced the cost of helical teeth speed changer, for the popularization of two jack shaft helical teeth speed changers is laid a good foundation.
Referring to Fig. 1, for traditional double jack shaft helical teeth speed changer, main tank jack shaft 4 front ends are supported on it on case of transmission front-end face 1 by tapered roller bearing, and main tank jack shaft 4 rear ends are supported on it on transmission case partition wall 2 by tapered roller bearing.Because the main tank gear is helical teeth, so in two jack shaft helical teeth speed changer transmission process, there is the effect of axial force in main tank jack shaft 4 two ends, in design in the past, tapered roller bearing has all been adopted in the support at main tank jack shaft 4 two ends, and tapered roller bearing cost height, and in the assembly process of every speed changer, all need to carry out the bearing play adjustment, the assembly technology complexity, the life-span is lower, the development of two jack shaft helical teeth speed changers of this serious restriction.Make the advantage of two jack shaft helical teeth speed changers to embody in actual applications.The present invention is based on theoretical calculation and actual tests shows, the axial force ball bearing (or roller bearing) that two jack shaft helical teeth speed changers are produced in transmission process can bear, and is higher than tapered roller bearing actual life.Referring to Fig. 3, the present invention changes to ball bearing (or roller bearing) with the spring bearing at two jack shaft helical teeth speed changer main tank jack shafts 4 two ends by traditional tapered roller bearing.Because ball bearing (or roller bearing) technology is very ripe, cost is low, good reliability, and in assembly process, do not need to carry out gap adjustment.So fundamentally solved the difficult problem of two jack shaft helical teeth speed changer practical application.
Referring to Fig. 2, for traditional double jack shaft helical teeth speed changer, odd-side jack shaft 5 front ends are supported on it on transmission case partition wall 2 by tapered roller bearing, and odd-side jack shaft 5 rear ends are supported on it on bonnet housing 3 by tapered roller bearing.Because the odd-side gear is helical teeth, so in two jack shaft helical teeth speed changer transmission process, there is the effect of axial force in odd-side jack shaft 5 two ends, in design in the past, tapered roller bearing has all been adopted in the support at odd-side jack shaft 5 two ends, and tapered roller bearing cost height, and in the assembly process of every speed changer, all need to carry out the bearing play adjustment, the assembly technology complexity, the life-span is lower, the development of two jack shaft odd-side helical teeth speed changers of this serious restriction.Make the advantage of two jack shaft helical teeth speed changers to embody in actual applications.The present invention is based on theoretical calculation and actual tests shows, the axial force ball bearing (or roller bearing) that two jack shaft helical teeth speed changers are produced in transmission process can bear, and is higher than tapered roller bearing actual life.Referring to Fig. 4, the present invention changes to ball bearing (or roller bearing) with the spring bearing at two jack shaft helical teeth secondary box of gearbox jack shafts two ends by traditional tapered roller bearing.Because ball bearing (or roller bearing) technology is very ripe, cost is low, good reliability, and in assembly process, do not need to carry out gap adjustment.So fundamentally solved the difficult problem of two jack shaft helical teeth speed changer practical application.
