Abstract
The utility model discloses a novel rotary table, and mainly applies to rotation of a solar tracking device, and situations such as factory industrial equipment needing to be borne and rotate. The rotary table comprises an upper rotary table board, a lower fixed seat, a wheel carrier and a driving unit; the driving unit which comprises a motor, a speed reducer and a pinion is mounted on the upper rotary table board; the lower fixed seat is a circular ring shaped component with a hole at the center; and holes evenly distributed along the hole at the center are formed on two end surfaces close to the hole at the center; the centers of the distribution circles of the holes coincides with the rotation center of the lower fixed seat; pintles passing through the holes on the lower fixed seat are fixedly connected to the lower fixed seat; the pinion are meshed with the evenly distributed pintles; the wheel carrier is provided with two cylindrical journals; and axes of the two journals are vertical to each other; a first rolling wheel and a second rolling wheel are arranged on the journals; the upper rotary table is borne on the lower fixed seat through the first and the second rolling wheels mounted at the bottom of the rotary table, and rotate around the lower fixed seat; and the driving unit can further comprise the speed reducer. The novel rotary table replaces the prior large-diameter rotary bearing structure, and causes installation and adjustment to be easy; and furthermore, the cost is very low.
Description
Technical field
The utility model relates to a kind of novel panoramic table, and the revolution, factory's tooling device etc. that are mainly used in solar tracking device need carrying and rotating occasion.
Background technology
The slew gear of present large-scale workbench particularly in the rotating application of solar energy tracking, mainly adopts pivoting support or large size bearing to wait and forms slew gear, and there is following subject matter in they:
1, manufacturing cost is very high.Because the bearing capacity that the solar energy tracking slew gear needs is little, but tactical diameter is bigger, as using pivoting support, then its manufacturing cost is very high, and the high of solar electrical energy generation tracking system cost brings very big obstacle for the application of solar energy;
2, the manufacturing cycle is long.At present the major part of slew gear is a pivoting support, because its special manufacturing process and material make the manufacturing cycle very long, it is unfavorable to bring for the fast development of Application of Solar Energy;
3, the raising of precision quality is difficult.Under the operating mode of major diameter underload, require pivoting support gently to approach, thereby make pivoting support yielding, influence the raising of the rotating accuracy of pivoting support;
4, make difficulty.To big and pivoting support underloading, wall is thin because diameter of movement is big, brings very big difficulty for the machining in making and the control of heat treatment deformation.
Summary of the invention
This purpose of this utility model is to overcome the deficiency that above structure is brought, and provides a kind of both economical and practical, again manufacturing, easy-to-install rotary table.
The purpose of this utility model is achieved in that
A kind of rotary table, comprise upper turntable face, lower fixed seat, wheel carrier, driver element, driver element comprises motor, reductor, pinion, driver element is installed on the upper turntable face, lower fixed seat is a ring-shape accessory, the centre also is provided with porose, both ends of the surface near the hole are provided with the hole uniform along the hole, the distribution circle center in hole overlaps with the centre of gyration of lower fixed seat, pin passes the hole on the described lower fixed seat, be fixedly connected on the lower fixed seat pinion and uniform pin engagement.
Wheel carrier is provided with the perpendicular cylindrical axle journal of two axial lines, and axle journal is provided with first roller, second roller.
First roller, second roller wheel bearing of last rotary table by being installed in its bottom is on lower fixed seat, and around the lower fixed seat revolution.
Also can comprise reductor in the described driver element.
Beneficial effect: this rotary table, by the driver element outputting power, pass to lower fixed seat, go up the rotary table rotation thereby drive, last rotary table is bearing on the lower fixed seat by the truck assembly that is installed in its bottom, and around the lower fixed seat revolution.
The utility model replaces original large diameter pivoting support structure, makes Installation and Debugging simple, and cost is extremely low, has the following advantages:
1, manufacturing cost is very low.Owing to adopt a large amount of standard components, make that the cost of whole device is extremely low, make this device can be used widely in the photovoltaic industry of cost sensitivity;
2, the manufacturing cycle is very short.Because wherein part mostly is standard component.Therefore, tissue is produced very simple, need not special equipment and processing technology, can finish the manufacturing of package unit in the short period;
3, the decline that can not bring the final assembly precision because of the difficulty in the processing.Because the precision of standard component can be controlled in this structure, thereby can improve the final precision of sleeve mechanism;
4, make, assemble simple.Part in this structure all can machine by machine tool, does not have special technology and special adjustment, gives to make and assemble to adjust to bring great convenience, and is convenient to the construction easily in the open air of photovoltaic industry.
