Abstract
The invention provides a planet gear installation structure for a double-crank planet gear reducer. The planet gear installation structure for the double-crank planet gear reducer comprises a supporting element and an installation element. The supporting element comprises a shaft. The shaft comprises a first connection part, a first installation part, a second installation part and a second connection part which are sequentially arranged. The installation element comprises an eccentric wheel provided with a connection hole. The second installation part of the shaft is arranged in the connection hole. The center line of the eccentric wheel deviates from the center line of the shaft. The shaft and the eccentric wheel are detachably connected. By the adoption of the planet gear installation structure for the double-crank planet gear reducer, the eccentric wheel and the shaft are detachably connected, so that detachment is easy, practicality is high, and production cost is reduced to a certain degree.
Description
Technical field
The invention belongs to plane table thermoconductivity meter field, especially relate to a kind of planetary pinion mounting structure of double-crank plane table thermoconductivity meter.
Background technique
In present plane table thermoconductivity meter, planetary pinion is paired use generally, therefore planetary crankshaft is driven to exist in pairs, in working procedure, because crankshaft is formed in one, if therefore there is damage, in order to ensure two planetary synchronisms in a crankshaft, need two crankshafts all to change, cause the raising of cost of production and the waste of assets.
Summary of the invention
In view of this, the present invention is intended to the planetary pinion mounting structure proposing a kind of double-crank plane table thermoconductivity meter, to solve the problem that the crankshaft that mates with planetary pinion raises because of the cost that can not generally cause.
For achieving the above object, technological scheme of the present invention is achieved in that
A kind of planetary pinion mounting structure of double-crank plane table thermoconductivity meter, comprise supporting member and installation elements, described supporting member comprises axle, described axle comprises the first joint, the first assembly department, the second assembly department and the second joint that set gradually, described installation elements comprises eccentric wheel, and described eccentric wheel is provided with attachment hole, and the second assembly department of described axle is arranged in attachment hole, the center line of described eccentric center line off-axis is arranged, and described axle and eccentric wheel removably connect.
Further, described eccentric wheel is connected by flat key with axle, and described flat key is arranged on one end that eccentric wheel protrudes described shaft centre line.
Further, the diameter of described first joint, the first assembly department and the second joint is identical, and the diameter of described second assembly department is greater than the diameter of the first joint.
Further, tool withdrawal groove is respectively equipped with between described second assembly department and the first assembly department, between this second assembly department and second joint.
Further, described first joint is provided with keyway.
Relative to prior art, the planetary pinion mounting structure of a kind of double-crank plane table thermoconductivity meter of the present invention has following advantage:
In the planetary pinion mounting structure of a kind of double-crank plane table thermoconductivity meter of the present invention, be arranged on axle owing to connecting planetary eccentric wheel by the mode removably connected, if damaging appears in an element therefore in axle and the eccentric wheel that is connected with this axle, only need change this element, therefore save raw material, reduce cost of production.
