Description

A kind of face gear reduction unit
Technical field
This patent belongs to machinery field more particularly to a kind of face gear reduction unit.
Background technology
Conic reducer is a kind of common type in helical gear reducer, the side that bevel gear is transmitted for changing power To application range is very extensive, but has the following defects:
(1) during Bevel Gear Transmission, the vertex of a cone of two bevel gears will overlap.If generating axial error, it will cause tight The unbalance loading phenomenon of weight.
(2) since bevel gear is many in the production process that is, in the fabrication process, processed first using pairing manufacture Go out pinion gear, the matched gear wheel used is then gone out according to the Gear shape process of pinion gear.Therefore, bevel-gear sett is using There cannot be interchangeability as roller gear in the process.Since pinion gear is easier to wear, fail faster, therefore when replacing Bevel-gear sett can only be replaced simultaneously.
(3) tooth surface shape of bevel gear (especially spiral bevel gear) is more complicated, in the fabrication process, the shape of the flank of tooth Also disunity, therefore different by the usual tooth surface shape of bevel gear that different manufacturers produce, parameter it is also different (such as Gleason system, Ao Likang bevel gears), this causes very burden for the processing and manufacturing of bevel gear, detection and repair.
Utility model content
To solve the above problems, the utility model discloses a kind of face gear reduction units.The gear drive of the utility model face It is to be driven by face gear and the intermeshing of cylindrical pinion gear to realize;It is axial to move since pinion gear is roller gear The error of movable property life has little effect transmission performance, significantly reduces gear assembly difficulty, and easy to process, this practicality is new Type also accelerates the fixed speed of retarder by special bolt arrangement.
To achieve the above object, the technical solution of the utility model is:
A kind of face gear reduction unit, including babinet;Lateral input shaft is connected with pinion gear across babinet, and pinion gear is circle Stud wheel, pinion gear are engaged with face gear;The periphery of face gear upper surface is formed with the engaging tooth engaged with pinion gear;Face Gear is connected with vertically arranged transmission shaft;Transmission shaft is connected with transmission gear, and transmission gear is connected with output gear;Output gear Wheel is connected with vertically arranged output shaft;The babinet is bolted component and is connected and fixed with lower connecting plate;The bolt Connecting component includes screw rod;Screw flight is connected with flexible swivel nut;Screw rod is formed with the wedge-shaped part that section is wedge shape, spiral shell Set lower part is formed with the wedge cavities coordinated with wedge-shaped part;The outer projection of swivel nut lower part forms snap ring;Screw coupling member is worn Babinet is fixed on lower connecting plate by the connecting hole crossed on babinet and lower connecting plate.
Further to improve, the input outer shaft sleeve is equipped with bearing, and bearing outside is equipped with bearing sleeve;Fitted bearing is installed There is oil seal cover;Bearing sleeve;Fitted bearing is equipped with oil seal cover and is fixed on babinet.
Further to improve, the swivel nut is process by flexible metal 30GrMnSiA.
The utility model also has the advantage that:
(1) face gear drive is to be driven by face gear and the intermeshing of cylindrical pinion gear to realize.Due to small tooth Wheel is roller gear, and the error that axial movement generates has little effect transmission performance, and it is difficult to significantly reduce gear assembly Degree.
(2) it is common roller gear with the gear-driven pinion gear in face, and for roller gear, processing method exists Domestic and international all comparative maturities, and interchangeability is good, need to only be replaced to pinion gear in serious wear, greatly reduces use Cost.
(3) compared to bevel gear, face gear has the unified theoretical flank of tooth, is conducive to processing and manufacturing, detection and repair.
(4) in the gear drive of face, the involute flank of roller gear has isometry.Installation error in transmission process In face transmission error is not will produce during gear drive.
(5) face gear drive has the registration of bigger, helps to improve bearing capacity, improves the stationarity of transmission.
(6) a kind of bolt fixing method of retarder is proposed so that the fixation of retarder and convenient disassembly, quickly, Convenient for the movement, repair and replacement of retarder.

Specific implementation mode
Embodiment 1
As shown in Figure 1, face gear reduction configuration schematic diagram.Bearing sleeve 4, axis are installed on the left side pivot holes of babinet 6 Bearing sleeve cylinder 4 is used for installing bearing 5 and positioning bearing outer ring in the axial direction.It is drilled with aperture on bearing sleeve 4, facilitates the profit in oil groove Lubricating oil flows back.Bearing sleeve 4 and oil seal cover 3 are bolted on reduction case 6.Pacify between input shaft 1 and oil seal cover 3 Equipped with sealing ring 2.The sleeve 7 of axially position effect is provided between pinion gear 8 and bearing 5.It installs the right side of input shaft There is pressing plate 9, and is fixed on input shaft 1 by screw 10.The axially position of face gear 12, one end by the shaft shoulder of gear shaft, The other end passes through sleeve 2.
As shown in Fig. 2, face gear drive schematic diagram.OI is instantaneous rotating shaft in figure, and 8 be cylindrical pinion gear, and 11 are Face gear.The nodal section of required angle γ=90 °, face gear 11 is plane, and the nodal section of pinion gear 8 is radius rP1Cylindrical surface. The intersection point P of the contact line O ' Q and instantaneous rotating shaft OI of two nodal sections are node.When normal work, the relative motion at node P is Pure rolling, the upper other points of nodel line O ' Q are sliding and roll.
Such as Fig. 3, Fig. 4, shown in Fig. 5, fixing bolt structural schematic diagram.Screw rod 21 and swivel nut 24 are connected through a screw thread, wedge shape Portion 23 is more than wedge cavities 26, and swivel nut is process by a kind of flexible metal 30GrMnSiA.First down by entire bolt arrangement The snap ring for being pushed into swivel nut is concordant with 25 lower face of lower connecting plate, then rotary screw 21, this make screw rod 21 with respect to swivel nut 24 to Lower movement, after wedge-shaped part 23 and the contact of wedge cavities 26, wedge-shaped part 23 makes 26 deformation expansion of wedge cavities, snap ring block lower connecting plate 25;Continue rotary screw 21 to installation is complete, as it can be seen in figures 5 and 6, the step of to eliminate fixing nut, accelerates deceleration The fixed speed of device.
Although the embodiments of the present invention have been disclosed as above, it is not restricted to institute in specification and embodiment Row use, it can be applied to various fields suitable for the present invention completely, for those skilled in the art, can Easily realize other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, this practicality It is novel to be not limited to specific details and the legend herein shown with description.
