Grease lubrication device for cam
Technical field
The utility model is mainly concerned with the mechanical transmission field, refers in particular to a kind of grease lubrication device for cam that is used for open cam.
Background technique
As mechanically operated conventional components, cam is able to extensive use on various machinery equipments.For example, in the packaging facilities that relates to medicine, food service industry, Chang Daliang adopts cam mechanism to carry out exercises, and the most of Open architecture that adopts of these cam mechanisms.But, for medicine, food service industry, its packaging facilities is all had special hygienic requirements, so one all adopts grease-added lubricating system to lubricating of existing open cam.In the prior art, when giving above-mentioned open cam grease-added, one adopts the mode of manually smearing.Thisly have many shortcomings by manually smearing to the grease-added mode of cam, for example workload is big, working efficiency low, it is inhomogeneous to smear, it is grease-added or the like often to forget.Therefore be necessary to design a kind of simple in structure, can easily realize open cam grease lubrication device.
The model utility content
The technical problems to be solved in the utility model just is: at the technical problem that prior art exists, the utility model provide a kind of simple and compact for structure, with low cost, installation and processing is convenient, easy and simple to handle, efficient is high, have the grease lubrication device for cam of preferable lubrication effect.
For solving the problems of the technologies described above, the utility model by the following technical solutions.
A kind of grease lubrication device for cam, it is characterized in that: comprise wobble component, greasing assembly and with the assembly of smearing of cam working face contact matching, the described assembly of smearing is fixed on the wobble component and can moves with wobble component, described greasing assembly comprises grease injection device and is used for to the greasing pipe of smearing the assembly stuffing that one end of described greasing pipe is connected with the outlet end of grease injection device.
As further improvement of the utility model:
Described wobble component comprises fork, fork axle and balance staff seat, and an end of described fork is fixed on the fork axle, described smearing on the other end that assembly is fixed in fork, and described fork axle is installed in the balance staff seat.
Described greasing pipe is installed on the fork.
One section of described greasing pipe is arranged in the swing axis inner chamber.
The described assembly of smearing is a rolling bearing, the outer rolling face of described rolling bearing and cam working face contact matching, and the outlet end of described greasing pipe is towards the outer rolling face of rolling bearing.
Compared with prior art, advantage of the present utility model just is: the utility model grease lubrication device for cam, simple and compact for structure, with low cost, installation and processing is convenient, easy and simple to handle, efficient is high, have preferable lubrication effect, greatly reduces working strength of workers; The utility model can directly be installed on the former open cam mechanism.

Embodiment
Below with reference to specific embodiment and Figure of description the utility model is described in further details.
As depicted in figs. 1 and 2, be respectively the structural representation of the utility model grease lubrication device for cam when being applied to cylindrical cam 6 and the structural representation when being applied to face cam 8, this cylindrical cam 6 and face cam 8 are open cam and are installed on the camshaft 7, and the principle that both lubricate is identical.Grease lubrication device for cam of the present utility model comprise wobble component, greasing assembly and with the assembly of smearing of cam working face contact matching, smearing assembly is fixed on the wobble component and can moves with wobble component, the greasing assembly comprises grease injection device 9 and is used for to the greasing pipe 4 of smearing the assembly stuffing that an end of greasing pipe 4 is connected with the outlet end of grease injection device 9.
In the present embodiment, wobble component comprises fork 3, fork axle 2 and balance staff seat 1, one end of fork 3 is fixed on the fork axle 2, smear on the other end that assembly is fixed in fork 3, fork axle 2 is installed in the balance staff seat 1, greasing pipe 4 is installed on the fork 3, and a section of greasing pipe 4 is arranged in swing axis 2 inner chambers 9 belows that are positioned at fork axle 2 of grease injection device.By wobble component, can guarantee to smear the influence that assembly can not be subjected to cam work, remain and the cam working face contact matching.
In the present embodiment, smear assembly and adopt rolling bearing 5, the outer rolling face of this rolling bearing 5 and cam working face contact matching, the outlet end of greasing pipe 4 is towards the outer rolling face of rolling bearing 5 or directly press close to the outer rolling face of rolling bearing 5.
During work, when through grease injection device 9 grease ups, lubricating grease can overflow from greasing pipe 4, adheres on the outer rolling face of rolling bearing 5.When open cam turned round, the outer rolling face of rolling bearing 5 will rotate thereupon, and at this moment, the lubricating grease that adheres on the rolling bearing 5 outer rolling faces will be applied on the working surface of open cam automatically, thereby finishes grease-added operation very like a cork.
The above only is a preferred implementation of the present utility model, and protection domain of the present utility model also not only is confined to the foregoing description, and all technological schemes that belongs under the utility model thinking all belong to protection domain of the present utility model.Should be understood that; for those skilled in the art; in the some improvements and modifications that do not break away under the utility model principle prerequisite; for example; smear assembly adopt the roll piece of other type or non-roll piece, greasing pipe 4 not to be installed on the fork 3 and directly tie up on the frame of the equipment of being located at, wobble component adopts the swing part of other type, grease injection device 9 is designed to quantitative charging point of automatic timing or the like, these improvements and modifications also should be considered as protection domain of the present utility model.
