Specific embodiment

The embodiments of the present invention is illustrated by particular specific embodiment below, those skilled in the art can be by this Content disclosed by specification understands other advantages and effect of the utility model easily.

It should be clear that this specification structure depicted in this specification institute accompanying drawings, ratio, size etc., only to cooperate specification to be taken off The content shown is not intended to limit the utility model enforceable restriction item so that those skilled in the art understands and reads Part, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size are not influencing Under the effect of the utility model can be generated and the purpose that can reach, should all still it fall in the revealed technology of the utility model In the range of appearance can cover.Meanwhile in this specification cited such as "upper", "lower", "left", "right", " centre " term, It is merely convenient to being illustrated for narration, rather than to limit the enforceable range of the utility model, the change of relativeness or tune It is whole, under the content of no substantial changes in technology, when being also considered as the enforceable scope of the utility model.

As shown in Figures 1 to 4, the utility model provides a kind of single-stage transfer gear cabinet knot with large capacity shoe cream room Structure, including cabinet 1 and case lid 2, the cabinet 1 are equipped with the second connecting hole 14, third connecting hole 22 on the case lid 2, bolt Across corresponding second connecting hole 14 and third connecting hole 22, the cabinet 1 and case lid 2 are connected.The front side of the cabinet 1 is set There is the shoe cream room 11 of opening, after the cabinet 1 and the connection of the case lid 2, the shoe cream room 11 becomes confined space, described Shoe cream room 11 is equipped with through-hole, uses for placing lubricating oil, the middle position of the shoe cream room 11 and the middle position of the case lid 2 In wearing central axis, gear is arranged on central axis, gear is located at the inside of the shoe cream room 11, the gear when central axis rotation It is rotated in the shoe cream room 11, so that the gear be made to lubricate incessantly.The side of the cabinet 1 is additionally provided with inner cavity 15, Transmission shaft is worn in inner cavity 15, the teeth portion of transmission shaft is engaged with the teeth portion of jackshaft, to form drive mechanism.

Since 11 capacity of shoe cream room in the prior art is smaller, the shoe cream room 11 of the utility model include ontology 111, And the increase-volume chamber 112 that the position from the ontology 111 close to lower part extends outward to form, more specifically, in fig. 1, The oil level line of lubricating oil is M in shoe cream room 1, and oil level line M should be arranged in for increase-volume chamber 112 hereinafter, the shape of increase-volume chamber 112 can be Regular shape or irregular shape, as long as being able to satisfy installation requirement, for example, increase-volume chamber 112 can be in ellipse arc, circle The shapes such as arc, rectangle, polygon, the shape of position corresponding with the increase-volume chamber 112 is answered identical on the case lid 2, is guaranteed The reliability of installation.In the present invention by setting increase-volume chamber 112, circular configuration is compared, the total amount of lubricating oil is increased Nearly 50%, to improve the performance of lubrication and heat dissipation.

As shown in Figure 4, it is preferable that be equipped with sealing ring 3 between the cabinet 1 and case lid 2, the shape of the sealing ring 3 should be with The shape of the shoe cream room 11 is corresponding, further increases the sealing performance of the shoe cream room 11.Preferably, on the cabinet 1 Equipped with first positioning hole 12, the position that first positioning hole 12 is corresponded on the case lid 2 is equipped with second location hole 21, and described first is fixed Position hole 12 and the second location hole 21 are by positioning finger setting, to solve the cabinet 1 and the case lid 2 due to shape Irregularly, the problem of positioning is difficult, installation dislocation.When the increase-volume chamber 112 is ellipse arc, the first positioning hole 12 is equipped with Two, the increase-volume chamber 112 is arranged in close to the position of lower part in one of them, another is arranged on the shoe cream room 11 under The opposite position of the first positioning hole 12 in portion；Second connecting hole 14 be equipped with 7, wherein on the shoe cream room 11 with long axis phase The both ends of friendship are respectively equipped with second connecting hole 14, and the shoe cream room 11 is located at the position above long axis equipped with 3 second companies Hole 14 is connect, underlying position is equipped with 2 the second connecting holes 14, by the position distribution of 7 the second connecting holes 14, makes described The sealing performance of shoe cream room 11 is more preferable.Preferably, multiple first for connecting with other component are additionally provided on the cabinet 1 to connect Hole 13 is connect, is reliably connect first connecting hole 13 with other component by bolt.
