Description
Technical field
The utility model relates to a kind of solar energy tracking generating drive bearing, the especially a kind of generating of the solar energy tracking for new energy field drive bearing.
Background technique
Solar energy tracking generating drive bearing of the prior art has following several mode: carbon steel base self-lubricating bearing, the embedded graphite bearing of copper base, plastic bearing.Carbon steel base self-lubricating bearing is with the carbon steel of high-quality for matrix, the spherical bronze layer of intermediate sintering, the ring sleeve of surface rolling teflon mixture.Realize solar energy tracking generating transmission shaft by sliding friction to rotate in the nut installing carbon steel base self-lubricating bearing.Its work basic principle is: be fixed on by carbon steel base self-lubricating bearing in two nuts of solar energy tracking generating, then the main shaft that generated electricity by solar energy tracking penetrates in carbon steel base self-lubricating bearing, by drive unit solar energy tracking generating main shaft with carbon steel base self-lubricating bearing in forward and backward two nuts for fulcrum, make solar energy tracking generate electricity main shaft follow the tracks of in carbon steel base self-lubricating bearing running track from sun rotate.Its advantage is to have higher wear-resisting property, carbon steel base self-lubricating bearing quality gently can reduce costs, but also there is certain shortcoming: its kind of drive is that sliding friction causes its transmission efficiency not high, there is good wear resistance need to carry out surface treatment to appearance, improve bearing cost greatly.
The embedded graphite shaft of copper base is with ring-type, copper sheathing with holes for matrix, is embedded by graphite and is fixed in copper datum hole.Realize solar energy tracking generating transmission shaft by sliding friction to rotate in the nut installing carbon steel base self-lubricating bearing, but have employed embedded graphite mode and reduce friction factor between transferring member.Its work basic principle is: be fixed on by embedded for copper base graphite bearing in two nuts of solar energy tracking generating, then the main shaft that generated electricity by solar energy tracking penetrates in the embedded graphite bearing of copper base, by drive unit solar energy tracking generating main shaft with the embedded graphite bearing of copper base in forward and backward two nuts for fulcrum, make solar energy tracking generate electricity main shaft follow the tracks of in the embedded graphite bearing of copper base running track from sun rotate.Its advantage is to have employed the friction factor that embedded graphite mode reduces between transferring member and improves transmission efficiency, but also there is certain shortcoming: its kind of drive is that sliding friction causes its transmission efficiency not high, copper itself is the material that a kind of price is more expensive, and many circular holes is processed by copper base thus substantially increases the cost of this bearing.
Plastic bearing take high molecular polymer as the annular plastics cover of material.Realize solar energy tracking generating transmission shaft by sliding friction to rotate in the nut installing plastic bearing.Its work basic principle is: be fixed on by plastic bearing in two nuts of solar energy tracking generating, then the main shaft that generated electricity by solar energy tracking penetrates in plastic bearing, by drive unit solar energy tracking generating main shaft with plastic bearing in forward and backward two nuts for fulcrum, make solar energy tracking generate electricity main shaft follow the tracks of in plastic bearing running track from sun rotate.It is little that its advantage is to have employed itself quality of PE family macromolecule material, and friction factor is less.But also there is certain shortcoming: its kind of drive is that sliding friction causes its transmission efficiency not high; PE family macromolecule material is a kind of somewhat expensive material, so the cost of plastic bearing is high; Under the thinner pressure at solar energy tracking generating main shaft of plastic bearing wall thickness concentrates situation, can there is larger resiliently deformable in bearing local, greatly reduce plastic bearing working life.
