Abstract
The utility model relates to a bearing, particularly a bearing applied to an engine connecting rod of a small-size petrol engine. The bearing is provided with a holder of which the circumference is uniformly distributed with rolling needles connected with a shaft in a rolling way. The outside of the holder is provided with a 15CrMo outer ring of which the inner wall is connected with the rolling needles in a rolling way. The outer ring 4 is provided with a flange 5, and a gap is arranged between the shaft 3 and the flange 5. The utility model has the advantages of novel design, favorable heat-sinking capability and convenient assembly with the connecting rod because of the outer ring arranged outside the bearing holder, reduces requirements for machining accuracy and material of the connecting rod, and can bear high torque force, high rotation speed and the impact force of a crankshaft connecting rod system.
Description
Affiliated technical field
The utility model relates to a kind of bearing, especially a kind of a kind of bearing that is applied on the miniature gasoline engine engine connecting rod.
Background technique
Miniature gasoline engine engine connecting rod generally only has supporting retainer and needle roller with bearing at present, needle roller directly is connected with tie rod holes inner ring face, because special working environment, needle bearing must bear impact force, the piston rod of cylinder blast, the effect of bent axle inertial force, therefore, this needle bearing must be born great centrifugal force, accelerating force, this has just determined the connecting rod endoporus to need higher processing precision to reach and has possessed certain antiwear property, general connecting rod adopts alloy steel material and after heat treatment carries out fine finishing, has increased cost of production.
Summary of the invention
To connecting rod endoporus precision and the too high requirement of connecting rod material, the utility model is set up the outer ring on the basis of original bearing when assembling with bearing and connecting rod in order to overcome above-mentioned miniature gasoline engine engine connecting rod.
The technological scheme that realizes the utility model purpose is: a kind of miniature gasoline engine engine connecting rod bearing, have retainer, be evenly equipped with needle roller on the retainer circumference, needle roller rolls with axle and is connected, in the retainer arranged outside outer ring is arranged, needle roller rolls with the outer ring inwall and is connected.
In order to prevent that retainer from coming off from the outer ring, further: the outer ring is provided with rib.
Consider the lubricant oil circulation, increase heat diffusion area, prevent the inordinate wear of running-in period, more further: between axle and rib, be provided with the gap.
In order to strengthen the mechanical property of outer ring, further: the outer ring is the 15CrMo outer ring.
The utility model modern design, the outer ring is set outside retainer, more convenient with the assembling of connecting rod, reduced Machining of Connecting Rod precision and material requirement, have good heat dissipation potential simultaneously, and can bear the impact force of high torsion, high rotating speed and crankshaft rod system.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1. 5. ribs, 6. gaps, 3. 4. outer rings of retainer 2. needle rollers
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Miniature gasoline engine engine connecting rod bearing as shown in Figure 1, have retainer 1, be evenly equipped with needle roller 2 on the retainer circumference, needle roller 2 rolls with axle 3 and is connected, in the retainer arranged outside outer ring 4 is arranged, needle roller 2 rolls with outer ring 4 inwalls and is connected, and comes off from outer ring 4 in order to prevent retainer 1, and outer ring 4 is provided with rib 5, consider the lubricant oil circulation, increase heat diffusion area, prevent the inordinate wear of running-in period, between axle 3 and rib 5, be provided with gap 6.The outer ring material is 15CrMo, and oozes altogether through C-N, makes it can bear the impact force of high torsion, high rotating speed and crankshaft rod system.
Owing to set up outer ring 1, when assembling with connecting rod, outer ring 1 connects with the load of connecting rod inner hole sleeve, installs more convenient.Connecting rod adopts aluminum alloy material, and processing technology is simple, has alleviated the load of motor, has saved cost.
Claims (3)
