It is specific embodiment of the utility model and with reference to accompanying drawing below, the technical solution of the utility model is made into one
The description of step, but the utility model is not limited to these embodiments.
As shown in Figure 1-Figure 3, a kind of spline for washing machine drum axle of the utility model includes body 100, external gear
110th, passage 120, installation passage 121, placed channel 122, round platform breach 123, internal gear 121a, oiling pipeline 130 and mistake
Filter plate 131.
In the prior art, the raw material for driving the spline of washing machine drum axle (not marked in figure) rotation are aluminium die casting
Part, in the utility model, the material that body 100 uses is powdered metallurgical material, is added in right amount on the basis of raw material
Copper powder so that the wearability of body 100 and rotproofness are greatly enhanced, in this way, spline production when will not be because of ring
Border high humidity and cause the accuracy of manufacture of product low, meanwhile, when drum shaft (not marked in figure) is running at high speed and long-time work
When making, spline is avoided because oxidation occurs and is rubbed with drum shaft (not marked in figure), causes spline and drum shaft (figure
In do not mark) fit clearance can be increasing situation, so that it is guaranteed that laundry function long-time stable work, and then give producer
Save substantial amounts of production cost；In addition, the density of spline is adjusted to 6.85-6.9g/cm by technician when producing spline3, from
And the strength and stiffness of spline are added, meet the needs of businessman.
Further, the outside of body 100 is installed with external gear 110, is offered inside body 100 for wearing drum shaft
The passage 120 of (not marked in figure), passage 120 include installation passage 121 and placed channel 122, installation passage 121 and positioning
Round platform breach 123 is provided between passage 122 so that when drum shaft (not marked in figure) is arranged in passage 120, round platform breach
123 can be used as detent mechanism, so as to which drum shaft (not marked in figure) positioning is arranged in passage 120, and then ensure drum shaft
The installation accuracy of (not marked in figure) and spline, the side of installation passage 121 are provided with internal gear 121a, when technician is by drum shaft
When (not marked in figure) installs with spline fitted, drum shaft (not marked in figure) need to be arranged in passage 120, and cause roller
Gear on axle (not marked in figure) engages with internal gear 121a, in this way, when drum shaft (not marked in figure) is around its center axis
During rotation, spline also can concomitant rotation；In the prior art, technician is to the spline that assembles and drum shaft (not marked in figure)
When carrying out operational maintenance, often spline is disassembled from drum shaft (not marked in figure), afterwards could will be in spline
Portion is lubricated, and in the utility model, oiling pipeline 130 is in body 100, and the one end of oiling pipeline 130 is positioned at this
On the end face of body 100, the other end of oiling pipeline 130 is located on the side of installation passage 121, and oiling pipeline 130 and installation
The UNICOM of passage 121, in this way, when technician carries out operational maintenance to the spline assembled, technician need to only inject lubricating oil
Enter in oiling pipeline 130 so that lubricating oil can be entered in the passage 120 of spline by oiling pipeline 130, in this way, can not only
Reduce the friction between spline and drum shaft (not marked in figure), meanwhile, can also facilitate technician to the spline that assembles and
Drum shaft (not marked in figure) is lubricated；Filter 131 is in oiling pipeline 130, in this way, the debris in passage 120 will
It will not enter in oiling pipeline 130, so as to avoid the situation that oiling pipeline 130 blocks, and then ensure oiling pipeline 130
Can normal work.
Filter 131 is located at oiling pipeline 130 close to one end of pipe laying, in this way, working as internal gear 121a and drum shaft
When (not marked in figure) is because of friction generation debris, filter 131 will stop that debris is entered in oiling pipeline 130 very first time,
So that it is guaranteed that lubricating oil can be entered smoothly in installation passage 121 by oiling pipeline 130, and drum shaft (is not marked in figure
Note) and internal gear 121a be lubricated, reduce drum shaft (not marked in figure) and internal gear 121a between friction.
Offered on filter 131 it is multiple be used for the lubrication hole 131a of lubricating oil of circulating, during work, technician is to oil fuel tube
The input in road 130 is injected into lubricating oil, and when lubricating oil is arrived to filter 131, lubricating oil just can pass through lubrication hole
131a is entered in installation passage 121, and the debris carried in lubricating oil can not be by lubrication hole 131a, so that it is guaranteed that lubrication
Oil can be lubricated to internal gear 121a and drum shaft (not marked in figure), and then reduce internal gear 121a and drum shaft (figure
In do not mark) between friction.
The diameter of placed channel 122 is more than the diameter of installation passage 121, and the diameter and internal tooth at the top of round platform breach 123
Wheel 121a root diameter is identical, and the base diameter of round platform breach 123 is identical with the diameter of placed channel 122, in this way, working as skill
When drum shaft (not marked in figure) is inserted in passage 120 by art person, installation passage 121 is corresponded on drum shaft (not marked in figure)
Position will pass through placed channel 122, and enter in installation passage 121, and engaged with internal gear 121a, drum shaft (figure
In do not mark) on correspond to the position of placed channel 122 and will be installed in placed channel 122, and when drum shaft (is not marked in figure
Note) on when corresponding to the position of round platform breach 123 and propping up locating notch, drum shaft (not marked in figure) will stop motion, in this way,
Just drum shaft (not marked in figure) can be positioned and be arranged in spline, so as to facilitate the operation of technician.
It is operation principle of the present utility model below：
Lubricating oil is injected into installation passage 121 by technician by oiling pipeline 130, so as to reduce internal gear 121a with
Friction between drum shaft (not marked in figure), and the setting of filter 131, are avoided that in passage 120 that debris enters oiling
The debris carried in pipeline 130 and in lubricating oil is entered in oiling pipeline 130, so that it is guaranteed that lubricating oil can smoothly enter
Into passage 120；Body 100 is made using powdered metallurgical material so that the wearability of body 100 and rotproofness obtain significantly
The raising of degree, so as to meet the needs of producer.
Specific embodiment described herein is only to the utility model spirit explanation for example.The utility model institute
Category those skilled in the art can make various modifications or supplement to described specific embodiment or using similar
