Abstract
The utility model relating to a bearing for the balance shaft of an engine double-shaft balancer is characterized in that the bearing is a sliding bearing formed by a balancer shaft and a bearing sleeve matched to the shaft. Adoption of the bearing in such a structure simplifies the assembly process, depresses the cost, saves the space, and provides the engineering design with great convenience.
Description
Technical field: the utility model belongs to engine balance device field, relates to a kind of balance shaft bearing of motor double-shaft balance device.
Background technique: four cylinder engine second-order inertia force unbalance, engine luggine are relatively more severe.This is a geneogenous problem in motivation design, the manufacturing, in order to overcome this problem, begin to develop this second-order inertia equilibrium of forces mechanism, present most of limousine all has been equipped with this four cylinder second-order inertia equilibrium of forces mechanisms, and the four-cylinder diffusion that progressively turns to minibus, Light-duty Vehicle, intermediate-size car, truck etc. to use.What the four cylinder second-order inertia equilibrium of forces mechanisms that present Cummins Corp develops adopted is needle bearing, the manufacture cost height, and assembling is trouble very, expends man-hour, has increased cost.Bearing lubrication is to provide by the mist of oil in the crankshaft room.
Summary of the invention: the utility model is in order to solve the problem that existing balance shaft bearing assembling is complicated, cost is high, a kind of balance shaft bearing of motor double-shaft balance device is proposed, it is characterized in that: described bearing is a sliding bearing, constitutes by the balace weight axle with the bearing housing of its coupling.Adopt the bearing of this structure, simplified linkage editor, reduced cost.
Description of drawings: Fig. 1 is the structural representation of the balance shaft bearing of the utility model motor double-shaft balance device;
Fig. 2 is the bearing housing structural representation of the balance shaft bearing of motor double-shaft balance device of the present utility model.
Embodiment: as shown in Figure 1, the balance shaft bearing of this motor double-shaft balance device is by balace weight axle 1 and the sliding bearing that constitutes with the bearing housing 2 of its coupling.Have the dynamic lubrication oil duct that man type grooving 3 constitutes on its centre bearer bush, with the angle of bearing housing end face be 10 °～80 °, width is 1mm～20mm, the degree of depth is 2mm～20mm, highly is 0.2mm～2mm.The lubricant oil of outside can be directed to bearing housing 2 the insides by grooving 3.Its principle is: when trunnion shaft moves with respect to bearing housing with high speed, lubricant oil is just driven high-speed motion by the ogival of man type grooving, and at this moment, a lubricant oil part is the direction along the man type grooving, move to bearing centre along the bearing play, this part lubricant oil just can lubricate whole bearing surface; Another part is driven high-speed motion by the trunnion shaft of high speed rotating, and bearing is played " dynamic lubrication " effect, and dynamic lubrication comprises two aspect effects: the one, and kinetic energy is converted into the pressure energy, and load is played the carrying effect; The 2nd, the bearing play that makes changes, and is descending, thereby produces oily contract carrying and lubrication.Wherein, kinetic energy is converted into the pressure energy, the machine oil that is exactly high speed rotating is sticked by the bearing housing surface, do not allow rotation, but because the pressure that bearing load produces less than the machine oil motion, so machine oil can not sticked by the bearing housing surface, under the effect that oily contract is lubricated, bearing can keep the better fluid lubricating status simultaneously.Thereby make that the friction factor of this bearing is enough little.In order further to improve greasy property, the opening end 4 of man type grooving can be widened intensification, it widens width is 5～40mm, the intensification degree of depth is 2～10mm, highly is 2mm～5mm; As shown in Figure 2, simultaneously, the shape of opening end 4 can be triangle, rhombus, rectangle and rectangular; Purpose is to strengthen oil inlet quantity by widening intensification oil duct junction size, reaches the effect of strengthening dynamic lubrication.
