Description
Technical field
The present invention relates to a kind of planet gaskets.
Background technique
In existing mixed dynamic gearbox, power dividing system --- planet gasket in planet row assembly is using biography
The ordinary construction of system, the alloy-steel sheet such as handled by nitrogen treatment or high-frequency quenching, or be molded into using resin material
The resin gasket of type.And above-mentioned planet gasket is during occurring relative motion with planet carrier and planetary gear, due to not having
There is anti-rotation measure and material wear ability is to be improved, therefore planet gasket is prone to wear, and biggish noise occurs.When planet pad
When the abrasion loss of piece reaches a certain level, planetary gear is easy to appear more serious unbalance loading, eventually leads to power dividing system ---
There is biggish risk in planet row assembly.
Summary of the invention
The present invention is intended to provide a kind of structure is simple, has anti-rotating function and the preferable planet gasket of wearability.
The present invention is realized by the following scheme:
A kind of planet gasket, including ontology, the ontology global sections are rounded, open up on the middle position of the ontology
There is through-hole, the through-hole global sections are in similar round, and the through-hole is made of several segments and the arc section of ontology concentric, described
Through-hole matches with corresponding planet pin shaft, is provided in the one side that the ontology is in contact with corresponding planet carrier end face several
One end of a along the circumferential direction uniform first groove and the first groove towards through-hole, the first groove the other end towards ontology
Outer edge, first groove on corresponding planet carrier boss correspond it is mating be entrenched togather, the ontology and phase
Several the second grooves being along the circumferential direction distributed, second groove are provided in the one side that corresponding planetary gear end face is in contact
One end be connected towards through-hole and with through-hole, for the other end of second groove towards the outer edge of ontology, described second is recessed
Slot is for storing lubricating oil.The thickness of ontology can be designed adjustment, generally 2.4~2.6mm as needed.The circular arc of through-hole
Segment number can be adjusted as needed, and the length of each section of arc section, diameter can be adjusted design as needed, logical to meet
Hole is conveniently sleeved on corresponding axis, the arc section composition through-hole of for example, two or more different lengths, diameter.First is recessed
Slot, the second groove quantity can be designed adjustment as needed.
Further, the face surface laser cladding that the ontology is in contact with corresponding planetary gear end face has compound painting
Layer, the material of the composite coating are wear-resistant material.The setting of composite coating, so that the surface abrasion resistance of planet gasket obtains very
The raising of big degree, to prolong its service life.
Further, the cross section of first groove is square, the boss size in size and corresponding planet carrier
Match, under normal circumstances, the width of the first groove is 2.8~3.2mm, and the depth of the first groove is 0.9~1.1mm.
Further, the cross section of second groove is integrally V-shaped, and the v-shaped opening of second groove is towards ontology
Outer edge, the V-arrangement of second groove merges end and is connected with through-hole.
Further, the width of whole V-shaped the second groove in the cross section is 0.6~0.8mm, depth is 0.2~
0.3mm, V-arrangement angle are 95~100 °.
A kind of planet gasket of the invention, structure is simple, conveniently recognized to make in the groove of ontology two sides setting different structure
With, the setting of the first groove, guarantee the close contact between planet gasket and corresponding planet carrier and can prevent planet gasket and
Without relative motion between corresponding planet carrier, play the role of anti-rotation, reduces planet gasket and the friction of corresponding planet carrier generates
Noise and abnormal sound；The setting of second groove can store enough lubricating oil, by the effect of lubricating oil, to reduce planet
Friction between gasket and corresponding planetary gear；Laser is used on the one side surface that ontology is in contact with corresponding planetary gear end face
The composite coating of melting and coating technique setting wear-resistant material makes planet gasket so that the compactness in the face is improved compared to ontology
Surface abrasion resistance is significantly improved, to prolong its service life.A kind of planet gasket of the invention, using being expert at
Star is arranged between planet carrier and planetary gear in structure, for preventing planetary gear end face and the excessive wear of planet carrier end face, ablation, is mentioned
The safety of high planet row structure.
Detailed description of the invention
Fig. 1 is the structural schematic diagram (one) of planet gasket in embodiment 1；
