Embodiment
Be to reach technological means and the effect that predetermined model utility purpose is taked for further setting forth the utility model, below in conjunction with accompanying drawing and preferred embodiment, embodiment, structure, feature and effect to according to the gear lubrication device that the utility model proposes are described in detail as follows.
For convenience of description, please refer to Fig. 1 and Fig. 2, the utility model embodiment's gear lubrication device 3 is illustrated as example on the swirl gear 100 that is applied in the machinery such as harbour grab crane, bucket-wheel stacker reclaimer, the utility model embodiment aims to provide a kind of gear lubrication device 3, application occasion to this gear lubrication device 3 does not limit, and therefore above-mentioned is not that utilization to this gear lubrication device 3 limits for example.This swirl gear 100 comprises intermeshing actuation gear 1, turntable bearing 2 and fixed bearing 4, and wherein actuation gear 1 is less gears for relative turntable bearing 2, and described actuation gear 1 is arranged on described fixed bearing 4.
The gear lubrication device 3 of the utility model preferred embodiment comprises cover body 32, lubrication management 34, supporting structure 36 and lubricant pump (not shown).
In the present embodiment, cover body 32 is the circular arc cover, comprises upper wall 32a, lower wall 32c and sidewall 32b.Upper wall 32a and lower wall 32c be arranged in parallel, and have the identical arc-shaped side of diameter.The shape of upper wall 32a and lower wall 32c can be the part of annulus.Sidewall 32b is circular arc and connects upper wall 32a and the arc-shaped side of lower wall 32c.Cover body 32 is by through the face A(of sidewall 32b axis Fig. 1) sectional shape that cut is "] " shape.Distance between upper wall 32a, lower wall 32c is slightly larger than the facewidth.Upper wall 32a offers near place, external arc limit two ends that two openings 322,324, two openings 322,324 lay respectively at upper wall 32a.In the present embodiment, opening 322,324 is the silk hole, and a hole is provided with the joint (figure is mark) that is connected with lubrication management 34, and the specification in a hole can be decided according to concrete condition.The radius of arc at the wall place of sidewall 32b is R1, and the Outside radius of actuation gear 1 is R2, and wherein R1 is greater than R2.
During use, cover body 32 is fixed on fixed bearing 4 by supporting structure 36, and the face of gear that makes cover body 32 press close to actuation gear 1 is installed, and the axle center O of cover body 32
2Adopt and the eccentric O in the axle center of actuation gear 1 position
1Arrange, the tooth top of actuation gear 1 is pressed close at the middle part of sidewall 32b, thereby forms oiling agent containing space 326(Fig. 3 dash area that two ends diminish gradually to the centre between the sidewall 32b of the flank of tooth of actuation gear 1 and cover body 32, crescent shape).
Start lubricant pump, determine that according to turning to of actuation gear 1 lubricating grease is filled with via the opening 322,324 of which lubrication connection, specifically can control by the distributor in the lubrication system pipeline and the interlock that turns to that drives actuation gear 1.As shown in Figure 1, when actuation gear 1 turned clockwise, oiling agent should be filled with by opening 322; And when actuation gear 1 was rotated counterclockwise, oiling agent should be filled with by opening 324.Drop to the oiling agent of oiling agent containing space 326 along with the rotation of actuation gear 1 is slowly taken to oiling agent containing space 326 stenosis, in this process, because the space narrows down, oiling agent is squeezed, make on actuation gear 1 flank of tooth and fully be stained with oiling agent, avoided to be deposited on because of gravity reason oiling agent the rough sledding of gear teeth face lower end.Along with the engagement of actuation gear 1 and turntable bearing 2, oiling agent is adhered to again on the flank of tooth of turntable bearing 2, finally realizes the lubricated of actuation gear 1 flank of tooth and turntable bearing 2 flank of tooth.
Be appreciated that oiling agent also can pass into lubrication management 34 by alternate manner, directly be connected with the lubricant container that is in a high position as lubrication management 34, oiling agent enters lubrication management 34 by action of gravitation.
Be appreciated that, adopt distributor according to the sense of rotation of actuation gear 1 determine with flow of lubricant wherein a lubrication management 34 are preferred versions of the present utility model, in practical application, a lubrication management 34 can also only be set, according to sense of rotation employing manually-operable connection lubrication management 34 and the corresponding opening 322 or 324 of actuation gear 1.
Be appreciated that the structure of cover body of the present utility model and structure and the shape that shape is not limited to above-mentioned cover body 32.The structure of cover body is as long as satisfy following the requirement: the part flank of tooth that can cover actuation gear 1; And form the oiling agent containing space that two end openings diminish gradually to the centre between the flank of tooth of actuation gear 1; Offer the opening that can pass into oiling agent on cover body, this opening is communicated with the oiling agent containing space.For instance, cover body can be the part of hollow ellipse ball, its do not have upper wall, lower wall and sidewall minute, when it covers the part flank of tooth of actuation gear 1 also can and the flank of tooth of actuation gear 1 between form the oiling agent containing space that two end openings diminish gradually to the centre.Again for example, cover body is the shape that rectangular-box half-and-half cuts, madial wall joins end to end by three and orthogonal plane forms, and that plane in the middle of this three dimensions and all line parallels of actuation gear 1 top circle, it can be realized equally: the part flank of tooth that covers actuation gear 1; And form the oiling agent containing space that two end openings diminish gradually to the centre between the flank of tooth of actuation gear 1.Again for example, opening is not limited to be opened in upper wall, can be opened in sidewall.
The utility model embodiment's gear lubrication device 3 comprises following advantage at least:
1, form the oiling agent containing space 326 that two end openings diminish gradually to the centre between cover body 32 and actuation gear 1, the oiling agent that is charged oiling agent containing space 326 is along with the rotation of actuation gear 1 is brought to oiling agent containing space 326 stenosis, the oiling agent that assurance is charged always is in compressed process, efficiently solve the lubrication problem of turntable bearing 2 flank of tooth and actuation gear 1 flank of tooth thereof, oiling agent distributes comparatively even on flank of tooth teeth directional direction.
2, this device is convenient to utilize the mode of electronic centralized lubrication to realize, and is simple in structure, easy to operate.
3, be beneficial to machinery raising self automation, intelligentized requirement.
the above, only embodiment of the present utility model, be not that the utility model is done any pro forma restriction, although the utility model discloses as above with embodiment, yet be not to limit the utility model, any those skilled in the art, within not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be not break away from the technical solutions of the utility model content, any simple modification that foundation technical spirit of the present utility model is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
