Description
Technical field
The utility model relates to field of bearings, particularly relates to a kind of necessary because of installation requirements for balancing axle or other
Be installed separately has the needle bearing assembly cutting formula retainer open.
Background technology
In some application scenario, for example, being installed on the bearing on balance shaft of engine, it is because installation question, and bearing is necessary
Subdivision is wanted to open assembling.In a duty cycle, the movement velocity of piston is very fast, and speed is very uneven for engine；Up and down
During dead-centre position, the speed of piston is zero, and when the middle position of upper and lower stop, the speed of piston reaches the highest.Due to work
Plug does high-speed straight-line motion repeatedly in cylinder, necessarily makes to produce on piston, piston pin and connecting rod very big inertia force.Though
So on connecting rod, the counterweight of configuration can balance these inertia force effectively, but only some moving-mass of the counterweight on connecting rod
Participating in linear motion, another part participates in rotating.In addition to upper and lower dead-centre position, also other various inertia force can not be complete
It is balanced, so that engine creates vibration, and then produce noise.These noises make driver or the sense of personnel by bus
To uncomfortable, and existing there is many to be not balance axle in the car, even if having, being also normally applied sliding bearing, so a lot
Engine works, in order to reduce energy consumption, select typically to select needle roller axle during rolling bearing when supporting balance axle on the engine
Hold, but, owing to needle bearing of the prior art is not suitable for separately assembling, therefore need design one to cut formula needle roller axle open
Hold, it is simple to it is installed.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of needle bearing having and cutting formula retainer open
Assembly, it is simple to it is installed on balance axle or is easy to need the technical field being installed separately to use at other, and this cuts formula rolling open
Needle bearing can reduce the energy consumption of engine, reduces noise, plays and protects environment, the purpose of raising ride comfort, and it
Also have that structure design is simple, fabricate easy advantage.
To achieve these goals, the technical solution adopted in the utility model is: a kind of have the rolling cutting formula retainer open
Needle bearing assembly, including retainer, retainer is provided with needle roller, it is characterised in that: described retainer sidewall is provided with along guarantor
Holding the opening of the axially cutting formation of frame, this opening includes open upper end face and open lower end face, and open upper end face is provided with draw-in groove, institute
Stating open lower end face and being provided with the lock dog with card slot fit, described lock dog is distributed in open lower end face end edge and opening respectively
In the middle part of lower surface, respectively end lock dog and middle part lock dog.
In said structure, when bearing is installed, retainer is in separating up and down, and open upper end mask has 3 draw-in grooves, respectively position
In two ends, open upper end face and middle part, open lower end mask has 3 lock dogs, respectively 2 end lock dogs and 1 middle part lock dog,
This hatch frame makes retainer be in free split state, it is simple to install, and passes through 3 lock dogs and 3 draw-in grooves after installing
Coordinate the effect playing locking bearing.The internal diameter of bearing during opening-like state can than closure state when bearing bore diameter big, but
This retainer is plastic material, and it has certain elastic deformability, and it can occur certain deformation in installation process, side
Civilian dress is joined, and after installation, after the locking of lock dog and card slot fit, bearing returns to original size, and above-mentioned lock dog and draw-in groove
Cooperation ensure that bearing install after size and installation before uniformity.
Arranging further as of the present utility model, described end lock dog is the barb-like draw-in groove direction towards open upper end face
Extending, described middle part lock dog is that inverted T shape structure is arranged, and described draw-in groove includes end draw-in groove and middle part draw-in groove, end draw-in groove and end
Portion's lock dog coordinates, and middle part draw-in groove coordinates with middle part lock dog.
In said structure, lock dog carries out sealed by end and middle part respectively, plays and further increases sealed fastness
Effect with stability.
Arranging further as of the present utility model, described end lock dog includes being extended by edge, open lower end face
Connecting sidewall, this connection sidewall free end has the hook portion bending inwardly.
In said structure, the cavity connecting between sidewall and hook portion then cooperatively forms location fit with end draw-in groove.
Arranging further as of the present utility model, the both sides end edge in described open lower end face is equipped with end lock
Block, and the end lock dog at two ends is symmetrical arranged with the center line of middle part lock dog for symmetry axis the right and left.
In said structure, the opening part of retainer is by three lock claw Structural lock this aperture positions of incompatible Guan Bi, i.e. 2 ends
Portion's lock dog and end card slot fit, 1 middle part lock dog and middle part card slot fit, i.e. install after being further ensured that retainer Guan Bi
Uniformity before finishing rear size and installing.
Arranging further as of the present utility model, the upper surface of described end lock dog is neat with the upper surface of middle part lock dog
Flat.
In said structure, the contour structure of end lock dog and middle part lock dog, it is simple to processing and manufacturing.
Using such scheme, the utility model has the advantage that this is cut formula needle bearing assembly open and achieves the axis of rolling
Hold and needing to split the use in the technical field installed, and on balance shaft of engine, it is achieved that with cutting formula needle roller axle open
Hold replacement sliding bearing, more energy-conserving and environment-protective, decrease environmental pollution, also add the comfortableness of rider simultaneously.
