Description
Technical field
This utility model is related to field of bearings, more particularly to one kind is used for balance shaft or other are necessary because of installation requirements
Be installed separately with the needle bearing for cutting formula retainer open.
Background technology
In some application scenarios, such as bearing being installed 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 electromotor；Upper and lower
During dead-centre position, the speed of piston is zero, and during position in the middle of upper and lower stop, the speed of piston reaches highest.Due to work
Plug does high-speed straight-line motion repeatedly in cylinder, necessarily causes to produce very big inertia force on piston, piston pin and connecting rod.Though
The counterweight for so configuring on connecting rod can effectively balance counterweight on these inertia force, but connecting rod only some moving-mass
Linear motion is participated in, another part participates in rotation.In addition to upper and lower dead-centre position, also other various inertia force can not be complete
It is balanced, so that electromotor generates vibration, and then produces noise.These noises make driver or the sense of personnel by bus
To uncomfortable, and it is existing have many to be there is no balance shaft in the car, even if having, sliding bearing is also normally applied, so a lot
Needle roller axle is typically selected when engine works select rolling bearing in order to reduce energy consumption, on the engine when supporting balance shaft
Hold, however, because needle bearing of the prior art is not suitable for separate assembling, therefore need design one kind to cut formula needle roller axle open
Hold, be easy to it to install.
Utility model content
In order to overcome the deficiencies in the prior art, this utility model to provide a kind of with the needle roller axle for cutting formula retainer open
Hold, be easy to it to be installed in balance shaft or be easy to the technical field being installed separately in other needs to use, this cuts formula needle roller open
Bearing can reduce the energy consumption of electromotor, reduce noise, play environmental protection, improve the purpose of ride comfort, and it is also
With structure design is simple, the easy advantage of processing and manufacturing.
To achieve these goals, the technical solution adopted in the utility model is：It is a kind of with the rolling for cutting formula retainer open

In said structure, when bearing is installed, retainer is in separate up and down, closing piece and the open lower end face in open upper end face
Groove separate, make retainer in free split state, the internal diameter of such bearing will be than in bearing during closure state
Footpath is big, but the retainer is plastic material, and it has certain elastic deformability, and certain change can occur in installation process
Shape, convenient for assembly, after installation, after the locking of closing piece and groove fit, bearing returns to original size, and above-mentioned closing piece with
The cooperation of groove ensure that the size after bearing installation and the concordance before installation.
Used as further setting of the present utility model, the open upper end face is provided with least 2 prominent closing pieces, and 2 are dashed forward
The closing piece for going out is spaced apart.
In said structure, 2 closing pieces and 2 groove fits are played and further increase sealed fastness and stability.
As further setting of the present utility model, cavity is connected between 2 prominent closing pieces, under the opening
It is provided between 2 grooves of end face towards the raised snapping block in open upper end face, the snapping block is adapted to the cavity.
It is sealed closing the lock of the aperture position, i.e., 2 by three lock claw structures at the opening of retainer in said structure
Block and groove fit, 1 snapping block coordinates with cavity, is further ensured that after retainer closure and installs rear size and install
Concordance before.
Used as further setting of the present utility model, one end composition that the closing piece of the protrusion is connected with open upper end face is prominent
The closing piece connection end for going out, prominent closing piece constitutes prominent closing piece connection end towards one end of groove, and the closing piece of the protrusion is in prominent
The pyramidal structure that the closing piece connection end that goes out is little and prominent closing piece free end is big is arranged, and the snapping block is connected with open lower end face
One end constitute snapping block connection end, the snapping block other end constitutes snapping block free end, and the snapping block is little in snapping block connection end
And the big pyramidal structure of snapping block free end is arranged.
In said structure, the retainer is made up of plastic material, and with certain elastic deformability, its free end is big, even
The little structure in end is connect, Anti-extrusion effect can be played after fastening.
Used as further setting of the present utility model, the edge of opening in the open lower end face is higher than snapping block upper surface,
The edge of opening in the open upper end face and the edge of opening cooperation in open lower end face, the cavity bottom surface in open upper end face and snapping
Block upper surface coordinates.
In said structure, snapping block upper surface does not flush with open lower end face both sides of the edge, can strengthen its intensity, it is to avoid
It is easy to lose.
Used as further setting of the present utility model, the snapping block is located at the middle part in open lower end face, and open lower end
2 grooves in face are distributed in the symmetrical setting in snapping block both sides.
In said structure, it is symmetrical set, structure is more stable, it is easy to processing and manufacturing.
Using such scheme, this utility model has advantages below：This is cut formula needle bearing open and realizes rolling bearing and exists
Need to split the use in the technical field installed, and on balance shaft of engine, realize with cutting formula needle bearing generation open
For sliding bearing, more energy-conserving and environment-protective, environmental pollution is reduced, while also add the comfortableness of rider.
