Abstract
The invention discloses a parallel type spin-on filter anti-looseness device and a parallel type spin-on filter anti-looseness method. The parallel type spin-on filter anti-looseness device comprises an anti-looseness ring and a plurality of sawtooth-shaped anti-looseness teeth, wherein the sawtooth-shaped anti-looseness teeth are evenly arranged on the outer side of the anti-looseness ring, each anti-looseness tooth comprises a windward side and a leeward side, and the gradient of the windward side is smaller than the gradient of the leeward side. According to the parallel type spin-on filter anti-looseness device, two or more spin-on filters which are arranged in a parallel connecting mode can be prevented from becoming loose at the same time, extra connection between the spin-on filters and other parts is not needed, the anti-looseness effect can be achieved only by means of the mutual restraint of adjacent units, and the problem of looseness of the filters caused by vibration, or load impact or change of operating temperature of the filters or a loading power device is effectively avoided. The parallel type spin-on filter anti-looseness device has the advantages of being simple in structure, low in cost, easy to implement, strong in universality and the like.
Description
Technical field
The invention belongs to the rotary filter loosing Prevention Technology field of internal-combustion engine equal power device, be specifically related to a kind of locking device for parallel rotary filter and anti-loose method.
Background technique
Filter cleaner is the critical elements of engine system; its effect is the impurity of removing in diesel oil, the lubricant oil; power plant in use; because self or power plant vibration equipment, load impacting or temperature change etc.; rotary filter produces the phenomenon that gets loose through regular meeting; and then cause and reveal, to the Security of motor and even car load and the influence of environment.Owing to reasons such as spatial constraints or installation conveniences, it is reliably fastening still not have ideal method at present.
Summary of the invention
At the problems referred to above, the invention provides a kind of parallel rotary filter locking device.
Technological scheme of the present invention is:
A kind of rotary filter locking device comprises anti-loose ring and the locking tooth of a plurality of zigzag fashion, and locking tooth is evenly distributed on the outside of locking tooth, and locking tooth comprises windward side and lee face, and the gradient of windward side is less than the gradient of lee face.
Preferred locking device adopts elastic material to make, and as hard rubber material, plastics, resin, nylon etc., it is effectively locking that these elastic materials can be realized, and does not influence the rotary filter installation.
A kind of rotary filter anti-loose method, comprise a plurality of rotary filters, described rotary filter is installed on the power plant by screw thread, rotary filter locking device of suit on the filter cylinder of each rotary filter, gap between adjacent filter cylinder is less than adjacent gear ring thickness sum, and the windward side of rotary filter locking device is towards the tightening direction of rotary filter.
The rotary filter locking device adopts the method for stickup or interference assembling to be sleeved on the rotary filter filter cylinder.
Beneficial effect of the present invention: can have characteristics such as simple in structure, separate, easy to implement, highly versatile for the rotary filter that is arranged in parallel more than 2 and 2.Use has the gear ring that certain flexible materials processing becomes to have the hangnail structure, with stickup or interference assembly method this device is fixed on the rotary filter filter cylinder, hangnail mutual extrusion on the utilized device prevents the filter cleaner counterrotating, thereby plays anti-loosening effect.Characteristics such as that this device has is simple in structure, with low cost, easy to implement, highly versatile.

Embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing.
First embodiment:
Rotary filter links together by screw thread and the power plant of bottom, before rotary filter is installed, adopt the method for stickup or interference assembling that the rotary filter locking device is sleeved on the rotary filter filter cylinder in advance, the filter cylinder of rotary filter and rotary filter locking device closely are adjacent to, relative movement can not take place, successively with suit the rotary filter of rotary filter locking device be installed on the power plant, because the windward side of the locking tooth of rotary filter locking device is towards the tightening direction of rotary filter, so rotary filter can easily be tightened and not have a stuck phenomenon; After rotary filter is tightened, along with the power plant operation, the trend that rotary filter becomes flexible again, this moment, rotary filter had the trend of contrary tightening direction motion, but because the locking tooth lee face of rotary filter locking device intermeshes, must cause adjacent rotary filter to rotate simultaneously, for adjacent rotary filter, rotation makes it rotate to tightening direction in opposite directions, and the loosening trend that this will prevent loosening rotary filter is assemblied on the power plant it securely.
Second embodiment:
Rotary filter links together by screw thread and the power plant of bottom, before rotary filter is installed, adopt to paste in advance or the method for interference assembling is sleeved on the rotary filter locking device wherein on the rotary filter filter cylinder, the filter cylinder of rotary filter and rotary filter locking device closely are adjacent to, relative movement can not take place, respectively with suit the rotary filter locking device rotary filter and not the rotary filter of suit rotary filter locking device be installed on the power plant, again rotary filter locking device cover is installed to after tightening on the rotary filter of suit rotary filter locking device not, and the windward side of locking tooth that guarantees the rotary filter locking device is towards the tightening direction of rotary filter.
Claims (5)
1. a rotary filter locking device comprises anti-loose ring and the locking tooth of a plurality of zigzag fashion, and it is characterized in that: locking tooth is evenly distributed on the outside of anti-loose ring, and locking tooth comprises windward side and lee face, and the gradient of windward side is less than the gradient of lee face.
2. rotary filter locking device according to claim 1 is characterized in that: the making of described locking device employing elastic material.
3. rotary filter locking device according to claim 2, it is characterized in that: described elastic material is hard rubber material, plastics, resin or nylon.
