Abstract
The utility model provides a universal joint for a rolling body joint, which aims at improving lubrication effect and timeliness of each component of the universal joint, prolonging lubrication time, reducing maintenance times and lowering maintenance cost. The universal joint for the rolling body joint is characterized by comprising a circular support and four pin shafts evenly arranged on the circular support. Each pin shaft is arranged on the circular support through a pin shaft hole, and grooves for accommodating lubricant are arranged on the surfaces where the pin shafts are contacted with the pin shaft holes. The grooves for accommodating the lubricant are arranged on the surfaces where the pin shafts are contacted with the pin shaft holes, the universal joint increases filling quantity of the lubricant, improves uniformity and duration of lubrication, avoids eccentric abrasion, prolongs service life of the pin shafts and even the universal joint, and reduces cost.
Description
Technical field
The utility model relates to a kind of rolling element and closes the universal joint of saving.
Background technique
Rolling element is realized the connection in upset joint through universal joint or cross joint often because upset needs, and then under the effect of drive motor, realizes rotary movement; Wearing and tearing for each parts of universal joint in the umklapp process seem particularly outstanding; Concern the smooth completion and the upset number of times of the rotary movement of whole rolling element, and the similar lubricant oil such as normally relying on coating butter that lubricates between each parts of present universal joint is realized, along with the realization of umklapp process; Butter disperses uneven; Phenomenons such as leakage happen occasionally, and cause bearing pin part serious wear and cause eccentric wear occurring, have quickened the wearing and tearing of bearing pin.
Summary of the invention
The purpose of the utility model provides a kind of rolling element and closes the universal joint of saving, and with the lubrication effect that improves its each parts and ageing, prolongs lubrication time, reduces maintenance times, reduces maintenance cost.
For reaching above-mentioned purpose; The utility model provides a kind of rolling element to close the universal joint of saving; Its special way is, comprises ring support, evenly is arranged on four bearing pins on this ring support; Each bearing pin is arranged on this ring support through a pin shaft hole, and the surface that each bearing pin contacts with this pin shaft hole is provided with in order to put the groove or the hole of hiding of oiling agent.
Above-mentioned groove is along the radially extension of said bearing pin.
Above-mentioned groove extends axially along said bearing pin.
The above-mentioned groove or the hole of hiding are the array-type setting, and adjacent grooves or the distance between the hole of hiding are 2 to 5.5mm.
The above-mentioned hole of hiding is circular, and its internal diameter is 1.5 to 2.5 mm, and the degree of depth is 1 to 1.5 mm.
The utility model has the advantages that: through the groove of kind of lubricant storage is set on bearing pin and face that pin shaft hole contacts; Increase the loading of oiling agent, improved lubricated uniformity and often, avoided the generation of eccentric wear phenomenon; Prolong the working life of bearing pin and even universal joint, reduced cost.
Description of drawings
Combine accompanying drawing and embodiment that the utility model is elaborated at present:
Fig. 1 is the structural representation of the universal joint that provides of the utility model.
Fig. 2 is the structural representation that the surface is provided with the bearing pin of the groove that radially extends.
Fig. 3 is the structural representation that the surface is provided with the bearing pin of axially extended groove.
Fig. 4 is the schematic representation of hole when being array-type and being provided with of hiding.
Among the figure: 1, inner ring; 2,3,4,5, the outer ring; 6; The groove or the hole of hiding.
Embodiment
For the lubrication effect of each parts of improving universal joint and ageing; Prolong lubrication time, reduce maintenance times, reduce maintenance cost; Present embodiment provides a kind of rolling element as shown in Figure 1 to close the universal joint of saving; Comprise ring support 1, evenly be arranged on four bearing pins 2,3,4,5 on this ring support 1, each bearing pin is arranged on this ring support 1 through a pin shaft hole; And the surface that each bearing pin contacts with this pin shaft hole is provided with in order to putting the groove 6 (as shown in Figure 2) of oiling agent, and extend along radially or axially (as shown in Figure 3) of bearing pin in this groove or the hole 6 of hiding.
As shown in Figure 4, the hole of hiding 6 is the array-type setting, and adjacent grooves or the distance between the hole of hiding are 2 to 5.5mm.Hide the hole be circular, its internal diameter is 1.5 to 2.5 mm, the degree of depth is 1 to 1.5 mm.
The advantage of this universal joint is: through the groove of kind of lubricant storage is set on bearing pin and face that pin shaft hole contacts; Increase the loading of oiling agent, improved lubricated uniformity and often, avoided the generation of eccentric wear phenomenon; Prolong the working life of bearing pin and even universal joint, reduced cost.
The above is merely preferred implementation of the present invention; Only do not represent and be limited by the examples; Other any do not deviate from any change, the modification done under the situation of spirit and principle of the utility model, substitutes, combination, simplify; All should be regarded as the substitute mode equivalent, all be included in protection scope of the present invention with the present invention.
