Embodiment
From Fig. 1, Fig. 2, Fig. 4, Fig. 5, the lubricating fitting of slide block type universal-joint spindle slide block of the present invention, it comprises gearwheel 2, seal closure 3, small gear 14; Gearwheel 2 is fixed in spindle 1 by backing plate 15, and seal closure 3 is equipped with in gearwheel 2 outsides, between seal closure 3 and gearwheel 2, seal ring 6 is housed, and airtight between seal closure 3 and gearwheel 2 gear teeth both ends of the surface have an end cap 5; In seal closure 3, be provided with a cavity, small gear 14 is installed in it, small gear 14 is wide with gearwheel 2, and is meshed with gearwheel 2, and airtight between its gear teeth both ends of the surface and seal closure 3 have an end cap 5; Seal closure 3 is provided with oil inlet hole 10; The gear teeth of gearwheel 2 are divided into two kinds: a kind of gear teeth a is along circumferentially having groove 13, and these gear teeth are for several continuously; Another kind of gear teeth b is the complete gear teeth, and gear teeth b is continuous two, is processed with radial hole 4 between the tooth root of two gear teeth b, radial hole 4 and axial bore 4 on gear 2 ' communicate, and axial bore 4 ' communicate with the lubricating point 9 of slide block 8 through oil circuit pipe fitting 7; Several gear teeth a and two complete gear teeth b interval cycle arrangement.Wherein, the tooth-shape angle of small gear 14 and gearwheel 2 is between 12 °～20 °.
In this device, the space that seal closure 3, gear 2, end cap 5, seal ring 6 form, only has oil inlet hole 10 to communicate with the external world with axial bore 4 ' two places.Seal closure 3 is fixing by support 16, and it is not rotated.
As a kind of optimal way of the present invention, backing plate 15 matches with the spill cambered surface of spindle 1 by its convex-shaped arc surface 17.On the endoporus of gear 2, process two grooves, equal fixing backing plate 15 in each groove, is convex-shaped arc surface 17 with the surface of contact of spindle 1 on backing plate 15, and the spill cambered surface of it and spindle 1 matches, and realizes axially locating; The backing plate 15 with convex-shaped arc surface 17 can also transmit this and install required torque, and does not resemble that common key connects and the intensity that affects spindle.
From Fig. 3, Fig. 6, as another kind of optimal way of the present invention, on seal closure 3, a cavity is set being equipped with on the symmetrical position of small gear 14, small gear 11 is installed in it; Small gear 11 is wide with gearwheel 2, and is meshed with gearwheel 2, produces the radial component of engaging force while being used for balance gear rim 2 and small gear 14 engagement.Meanwhile, in order not hinder flowing of drier oil, all gear teeth of small gear 11 are all along circumferentially having groove 12, in order to Oil Guide.
For convenient, install and processing, seal closure 3 is divided into sealing cover body and closing cap two-part; Sealing cover body is split-type structural, two-part, consists of, and can connect by hinged bolts between the two.When seal closure only has a cavity, closing cap is one, is fixed on a side of sealing cover body, and the semicolumn cavity that it is inner and the half-cylindrical cavity of sealing cover body have formed a complete circular cavity, are used for installing small gear 14.When sealing is covered with two cavitys, closing cap is two, be fixed on symmetrically the left and right sides of sealing cover body, the semicolumn cavity that it is inner and the half-cylindrical cavity of sealing cover body have formed two complete circular cavities, are used for installing small gear 14,11.For convenient, install and processing equally, gear 2 is also split-type structural, between two-part, can connect by hinged bolts.
According to slide block size and load condition, 4～8 lubricating points can be set on slide block 8, the radial hole 4 between gearwheel 2 gear teeth b tooth roots and coupled axial bore 4 ' number equate with the quantity of lubricating point 9.
In this device, gearwheel 2 numbers of teeth are many, and small gear 11,14 numbers of teeth seldom, and adopt normal shift; Their tooth-shape angle is less, between 12 °～20 °; Adopt less backlash.
The backlash of supposing gear is below zero, engagement process is set forth: as shown in Figure 7, complete gear teeth b ' and b when gearwheel 2 " just contacted while entering engagement gear teeth b ', b " and 14 with certain gear teeth 14 ' top on small gear 14 ' surround a sealing figure CDEFG (state i); Two engaging gears are rotated further, gear teeth b ', b " and 14 ' surround one to seal figure JD ' E ' HG ' C ' (state ii); Be rotated further again, gear teeth b ', b " and 14 ' surround one to seal figure KD " E " G " C " (state iii).Figure CDEFG equates with KD " E " G " C ", and figure JD ' E ' HG ' C ' Area Ratio they are little, be that respectively sealing in figure of changing in engagement process is minimum.Because small gear is wide greatly, gear teeth two ends have end cap to block, this sealing figure and two end cap surround sealing between cog die cavity, the between cog near closed hollow ring volume of three kinds of states is unequal, state i and state iii volume are maximum, state ii volume is minimum, and sealing between cog die cavity volume that the root of gearwheel 2 forms is large and change also large.Equally, in this process, the gear teeth 14 of small gear 14 ', 14 " with certain gear teeth b of gearwheel 2 " also can surround the sealing figure of a series of changes shapes, but because its tooth-shape angle is little, the few and displacement of the number of teeth, so the sealed volume that its root forms is little and change little.That is to say, when having the drier oil of certain pressure, be introduced into, during gear operation, drier oil is just full of whole seal space.When engagement is from state i during to state ii, from big to small, pressure raises between cog enclosed volume, and drier oil is just extruded by force from tooth root through hole, thereby has realized lubricating slide block.When engagement is from state ii during to state iii, from small to large, pressure decreased is negative pressure even between cog enclosed volume, adapts to position for this reason compensating groove or increase gap are set at end cap, makes it to communicate with there being the drier oil of certain pressure, sheds negative pressure, and this stage is force feed not.
