Abstract
The utility model relates to a sliding bearing of an axle balance shaft, which aims to solve the technical problems that the conventional sliding bearing is easy to abrade and the service life is short. The sliding bearing of the axle balance shaft comprises a ring-shaped body and is characterized in that a plurality of uniformly-distributed oil grooves are formed on one side end face of the body; the oil grooves are sector-shaped and the depths of the oil grooves range from 0.5mm to 1 mm; the symmetrical centerlines of the oil grooves are tangent to the inner circumferential surface of the ring-shaped body; and two positioning holes are also formed on the body symmetrically along the diameter.
Description
Technical field
The utility model relates to a kind of engine fittings, especially the sliding bearing of vehicle bridge trunnion shaft.
Background technique
Vehicle bridge trunnion shaft (being also referred to as " balancer weight ") is exactly the balace weight that a kind of metal of installing in the side of motor inside crankshaft is made, about being used in engine operation, reducing or rocking tendency up and down, and the vibrations that produce when offsetting engine running; Trunnion shaft essence is an eccentric shaft, and its rotating speed is identical with bent axle but sense of rotation and bent axle are opposite.
The vehicle bridge trunnion shaft is positioned on the bearing support by sliding bearing usually.Existing vehicle bridge trunnion shaft sliding bearing is a cirque structure, makes substrate with carbon steel, and at surperficial sintering thin copper layer or thin aluminium lamination, frictional behavior is good by sintering process; But in actual use, still can occur causing the accident of seize to take place because of lacking lubricant oil.
The model utility content
The purpose of this utility model is the deficiency that overcomes in the above-mentioned background technology, and a kind of vehicle bridge trunnion shaft sliding bearing that improves structure is provided, and this sliding axle is promised and had characteristics not easy to wear, long service life.
The technological scheme that the utility model proposes is: a kind of vehicle bridge trunnion shaft sliding bearing comprises the body of ring; A side end face that it is characterized in that described body is shaped on several equally distributed oil grooves.
Described oil groove is fan-shaped, and the groove depth of oil groove is 0.5-1mm.
The inner peripheral surface of the symmetrical center line of described oil groove and ring body is tangent.
Also be shaped on two positioning holes of arranging along diameter symmetry on the described body.
The beneficial effects of the utility model are: owing to be shaped on oil groove on the sliding bearing, have certain oil storage function, and be easy to form stable lubricant film, can effectively prevent because of phenomenons such as dry friction that oil starvation causes, seizes; In addition, arc oil groove and diameter form certain included angle, can significantly improve the holdup time of lubricant oil in oil groove, so the utility model is not easy to wear, can prolong 2-3 working life doubly.

Fig. 2 is the structural representation of looking up of the present utility model.
Embodiment
A kind of vehicle bridge trunnion shaft sliding bearing comprises the body 1 of ring; A side end face that it is characterized in that described body is shaped on several equally distributed oil grooves 2 (8 oil grooves of demonstration among the figure; Also can increase and decrease oil groove quantity as required).
Described oil groove is fan-shaped, and radius R 2 can be determined as required at the bottom of the arc top radius R 1 of oil groove and the arc; As recommendation, R may be selected to be 10-20cm.
The groove depth of oil groove is recommended as 0.5-1mm.
As recommendation, the symmetrical center line 5 (dotting among the figure) of described oil groove is tangent with the inner peripheral surface of ring body.
Also be shaped on two positioning holes of arranging along diameter symmetry 3 on the described body.Can pass positioning hole with screw during installation, sliding bearing is positioned on the bearing support.
Adopt imprint process when the utility model is made, once form uniform oil groove; Can enhance productivity fast; And finished product does not have the burr of milling.Oil groove arc top radius is identical with radius at the bottom of the arc, forms the sector structure that is in tilted layout.Adopt two hole modes, can effectively realize the location of bearing.
Claims (4)
