Abstract
The utility model discloses a kind of ball cage of replaceable lubricating grease, comprise housing and be located at the star sleeve in housing, and the half shafts to be connected with star sleeve, and be located at the multiple steel balls between star sleeve and housing by retainer, and be connected to the dust-proof cover between housing and half shafts; Described dust-proof cover is wavy, has a deep gouge bottom it, and the side of deep gouge is provided with greasing mouth, and the inside of described greasing mouth is provided with valve body; Each wave circle inside of described dust-proof cover is provided with shaping loop; This ball cage is provided with greasing mouth on dust-proof cover, replacing lubricating grease can be carried out by it, overall without the need to dismantling ball cage, change fat convenient, quick, time saving and energy saving, the deep gouge simultaneously set by dust-proof cover is not only convenient to change fat operation, also its damage rotated by external force can be prevented, set shaping loop further enhancing its radial strength, and set damping device enhances its compressive resistance, effectively raises the working life of dust-proof cover.
Description
Technical field
The utility model relates to a kind of ball cage of replaceable lubricating grease, belongs to AE field.
Background technique
Ball cage is the power transmitting deice between motor car engine and driving wheel, for the tractive force that provides automobile required under various operating mode and the speed of a motor vehicle, make both can coordinate change and have enough excursions simultaneously, ensure that vehicle right and left drives wheel can adapt to differential requirement.The structure of ball cage generally comprises housing and is located at the star sleeve in housing, retainer, steel ball, ball cage one end is connected with half shafts, and need lubricating grease be provided with in ball cage inside, lubricating grease set by its inside gradually can reduce lubrication effect in the process of Long-Time Service, usually because the fricative impurity of internal mechanical also can be mixed in lubricating grease, therefore need after long-term use to change lubricating grease in time, all ball cage is taken apart change under normal circumstances, such mode trouble very, waste time and energy, be not easy to operation, secondly, in prior art, the dust-proof cover of ball cage also extremely easily damages.
Model utility content
For solving the problem, the utility model proposes a kind of rational in infrastructure, changing that fat is convenient, the ball cage of the replaceable lubricating grease of long service life.
The technological scheme that the utility model adopts is: a kind of ball cage of replaceable lubricating grease, comprise housing and be located at the star sleeve in housing, and the half shafts to be connected with star sleeve, and be located at the multiple steel balls between star sleeve and housing by retainer, and be connected to the dust-proof cover between housing and half shafts; Described dust-proof cover is wavy, has a deep gouge bottom it, and the side of deep gouge is provided with greasing mouth, and the inside of described greasing mouth is provided with valve body; Each wave circle inside of described dust-proof cover is provided with shaping loop.
Further, the mouthpiece cover of described greasing mouth is equipped with lid.
Further, described shaping loop is made by steel wire.
Further, also damping device is provided with between each wave circle outside described dust-proof cover.
Further, described damping device is the elastic rubber ring of the V-shaped mechanism in cross section.
Compared with prior art, it has following beneficial effect to the utility model:
The ball cage of replaceable lubricating grease of the present utility model is provided with greasing mouth on dust-proof cover, replacing lubricating grease can be carried out by it, overall without the need to dismantling ball cage, change fat convenient, quick, time saving and energy saving, the deep gouge simultaneously set by dust-proof cover is not only convenient to change fat operation, also its damage rotated by external force can be prevented, set shaping loop further enhancing its radial strength, and set damping device enhances its compressive resistance, effectively raises the working life of dust-proof cover.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1-housing; 2-star sleeve; 3-half shafts; 4-retainer; 5-steel ball; 6-dust-proof cover; 7-deep gouge; 8-greasing mouth; 9-valve body; 10-shaping loop; 11-lid; 12-damping device.
Embodiment
Clearly understand to make the purpose of this utility model, technological scheme and advantage, below in conjunction with drawings and the embodiments, the utility model is further elaborated, should be understood to, embodiment described herein only in order to explain the utility model, and is not used in restriction the utility model.
The ball cage of a kind of replaceable lubricating grease as shown in Figure 1, comprise housing 1 and be located at the star sleeve 2 in housing 1, and the half shafts 3 to be connected with star sleeve 2, and be located at the multiple steel balls 5 between star sleeve 2 and housing 1 by retainer 4, and the dust-proof cover 6 be connected between housing 1 and half shafts 3, form confined space each other; Described dust-proof cover 6 is in wavy, and have a deep gouge 7 bottom it, the side of deep gouge 7 is provided with greasing mouth 8, the inside of described greasing mouth 8 is provided with valve body 9; Lid 11 is equipped with in the mouthpiece cover of greasing mouth 8, when needing add or change lubricating grease, open lid 11 and the valve body of greasing mouth 8, by syringe and can by lubricating grease extract out and inject, generally some lubricating grease sinks in deep gouge 7, it both can be convenient to change, and also can form certain gravity and form dust-proof cover 6 counterweight, rotated by external force to prevent ball cage dust-proof cover 6 when tilting.
In order to prevent dust-proof cover 6 to be out of shape in the process used, each wave circle inside of described dust-proof cover 6 is provided with shaping loop 10, and this shaping loop 10 is made by steel wire, to strengthen the radial strength of dust-proof cover.
In order to reduce the peak-to-peak pressurized situation of dust-proof cover 6 ripple, be also provided with damping device 12 between each wave circle outside described dust-proof cover 6, described damping device 12 is the elastic rubber ring of the V-shaped mechanism in cross section.
The ball cage of replaceable lubricating grease of the present utility model is provided with greasing mouth on dust-proof cover, replacing lubricating grease can be carried out by it, overall without the need to dismantling ball cage, change fat convenient, quick, time saving and energy saving, the deep gouge simultaneously set by dust-proof cover is not only convenient to change fat operation, also its damage rotated by external force can be prevented, set shaping loop further enhancing its radial strength, and set damping device enhances its compressive resistance, effectively raises the working life of dust-proof cover.
Embodiment recited above is described preferred implementation of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that related domain ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
