Abstract
The utility model discloses a device for eliminating axial force in running of a helical gear shaft adopting a belleville spring. The device comprises a bottom plate of a gear chamber (1), a gear chamber (4), an angular contact bearing (2), the belleville spring (5), a helical gear shaft (3) and a bearing pressing plate (6), wherein the non-axial force facing end of the helical gear shaft (3) as power output at two ends is radially and axially fixed and positioned by depending on the external ring of the angular contact bearing (2), and the other end of the helical gear shaft (3) is additionally provided with the belleville spring (5) to axially position the angular contact bearing (2). In the helical gear transmission system, the axial force generated by the helical gear is overcome without needing the herringbone gear with large processing difficulty and high cost; the axial force generated in the running process of the helical gear shaft can be effectively reduced by little axial deformation of the belleville spring; the device is stable and reliable, compact in structure, suitable for high-speed, heavy-load and heavy working conditions, low in cost, convenient to maintain, and wide in application range.
Description
Technical field
The utility model belongs to Machine Design middle gear transmission field, and especially a kind of helical gear shaft axial force cancellation element in service that adopts belleville spring, is effectively applied in spiral gear drive mechanism.
Background technique
In Machine Design gear transmission field, engagement property is good because having for helical gear, stable drive, noise is little, bearing capacity is strong, be applicable to the advantages such as high-speed overload operating mode is used widely, but helical gear itself is existent defect also: helical gear in service can produce end thrust, this end thrust is harmful to, by the frictional loss increasing in transmission device, even destroy train traveling comfort, so should adopt various measures, reduce or eliminate this end thrust.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, a kind of helical gear shaft axial force cancellation element in service that adopts belleville spring is provided, design by belleville spring and angular contact bearing is arranged in pairs or groups, effectively eliminate the axial force of helical gear shaft generation in service, and without adopting processed complex and the higher double hclical bevel gear of cost to realize this function, effectively cost-saving, be the practical technique of a kind of effective improvement and huge breakthrough.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals to be achieved: a kind of helical gear shaft axial force cancellation element in service that adopts belleville spring, by gear chamber base plate (1), gear chamber (4), angular contact bearing (2), belleville spring (5), helical gear shaft (3) and bearing plate (6) form, an angular contact bearing is respectively installed at helical gear shaft two ends, described helical gear shaft (3) non-axial force relies on angular contact bearing (2) outer ring in radial and axial stationary positioned towards end, the other end by the belleville spring (5) that installs additional by angular contact bearing (2) axially locating.
Owing to adopting technique scheme, advantage of the present utility model and beneficial effect are:
1. the utility model is in Helical gear Transmission system, without adopting difficulty of processing herringbone gear large, that cost is high to overcome the axial force that helical gear produces.
2. by the reasonable Arrangement to belleville spring and angular contact bearing, can effectively reduce the axial force in helical gear shaft running by the axial less deformation of belleville spring, reliable and stable.
The utility model compact structure, be applicable to the heavy operating modes such as high-speed overload.
4. equipment is simple, cheap, easy to maintenance, applied widely.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with embodiment and 1 pair of the utility model of accompanying drawing, be further described.
As Fig. 1, the non-herringbone gear of helical gear shaft 3(that structure of the present utility model is mainly exported by gear chamber base plate 1, gear chamber 4, angular contact bearing 2, belleville spring 5, two ends drive) and bearing plate 6 formations.In helical gear train, helical gear shaft angular contact bearing 2 radial locations for 3 two ends, and when helical gear shaft two ends are used as power output source, increase with rotating speed and load, the end thrust that helical gear shaft produces will progressively increase, and now end thrust will be destroyed the normal axial play of two ends angular contact bearing; When end thrust is excessive while causing bearing axial play to surpass the predetermined play of bearing itself, may cause bearing enclose to come off, thereby affect whole train reliability of operation.In order to suppress this end thrust, the angular contact bearing 2 radial and axial stationary positioned in outer ring by helical gear shaft 3 non-axial forces towards end, the other end coordinates angular contact bearing 2 to install a belleville spring 5 additional according to designing requirement, with belleville spring 5 by the axially locating of angular contact bearing 2, after train running, belleville spring 5 is axially having less deformation, produce larger axial reaction force, the axial motion opposite direction of this power and helical gear shaft, will effectively suppress the axial motion of helical gear shaft 3 simultaneously.
Claims (1)
1. adopt the helical gear shaft axial force cancellation element in service of belleville spring, by gear chamber base plate (1), gear chamber (4), angular contact bearing (2), belleville spring (5), helical gear shaft (3) and bearing plate (6), formed, it is characterized in that, an angular contact bearing (2) is respectively installed at helical gear shaft two ends, described helical gear shaft (3) non-axial force relies on angular contact bearing (2) outer ring in radial and axial stationary positioned towards end, the other end by the belleville spring (5) that installs additional by angular contact bearing (2) axially locating.
