Abstract
A clutch with a temperature control protection device comprises a transmission shaft, a bearing, a spring, a main wheel hub, an accessory wheel hub, a permanent magnet, a temperature sensing magnet and a guide key, wherein the bearing and the spring are respectively connected with the transmission shaft; the wheel hubs are connected with the bearing; the guide key is connected with the wheel hubs; and the spring is connected between the main wheel hub and the accessory wheel hub. The clutch is characterized in that the permanent magnet is also connected with the main wheel hub; the temperature sensing magnet is connected with the accessory wheel hub; and the temperature sensing magnet is corresponding to the permanent magnet in position. The clutch has the technical effect that the clutch is disconnected when the magnetic property of a magnetic material drops dramatically when the magnetic material is arranged at an inner point, thereby preventing superhigh temperature in the chassis to protect other main parts.
Description
Technical field
The utility model relates to a kind of clutch, particularly a kind of clutch with the temperature control protective gear,
Background technique
Present mechanical transmission usually will be used clutch, reaches the purpose of transmitting torque and motion, and the pivot friction heating in the transmission shaft high speed rotating of clutch, gear-box easily produces high temperature, causes temperature in chassis too high, and its parts are burnt out.
Summary of the invention
The purpose of this utility model is to provide a kind of clutch with the temperature control protective gear, and the wheel hub of clutch is thrown off automatically when temperature is too high, and transmission shaft idle running can not assembled high temperature and burn out other critical piece.
The utility model is achieved like this, it comprises transmission shaft, bearing, spring, the main wheel hub is paid wheel hub, permanent magnet, temperature-sensitive magnet, feather key, difference connection bearing, spring connect wheel hub on the bearing on transmission shaft, are connected with feather key on the wheel hub, the main wheel hub is connected spring with paying between the wheel hub, it is characterized in that being connected with permanent magnet on the main wheel hub, paying connection temperature-sensitive magnet on the wheel hub, temperature-sensitive magnet and permanent magnet position match.
Technique effect of the present utility model is: utilize magnetic material when curie temperature, magnetic sharply descends, and makes throw-out-of clutch, avoids temperature in chassis too high, protects other master unit.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
In the drawings, 1, transmission shaft 2, bearing 3, spring 4, main wheel hub 5, permanent magnet 6, temperature-sensitive magnet 7, pay wheel hub 8, feather key
Embodiment
As shown in Figure 1; the utility model comprises transmission shaft 1; bearing 2; spring 3; main wheel hub 4; pay wheel hub 7; permanent magnet 5; temperature-sensitive magnet 6; feather key 8; difference connection bearing 2 on transmission shaft 1; spring 3; connect wheel hub on the bearing; be connected with feather key 8 on the wheel hub; main wheel hub 4 is connected spring 3 with paying between the wheel hub 7, it is characterized in that being connected with on the main wheel hub permanent magnet 5, is paying connection temperature-sensitive magnet 6 on the wheel hub; temperature-sensitive magnet and permanent magnet position match; the utility model is having fluid medium and other working mediums or transmission of heat preferably in axle and the cabinet, and when reaching curie temperature according to magnetic material, the fall into disarray of magnetic moment is unordered; magnetic force sharply descends; this characteristic is installed in temperature-sensitive magnet 6 on pair wheel hub, and curie temperature is set in bearing; following certain point of other workpiece Maximum operating temperatures such as gear; when temperature reaches the magnetic material curie temperature; magnetic material becomes paramagnet by ferromagnet, and magnetic disappears, under the effect of spring 3 or other external force; two wheel hubs are thrown off; transmission shaft idle running descends and also can not fill the span of a man's arms automatically even separates the back temperature, wait exclude fault after; the people is for filling the span of a man's arms; its permanent magnet 5 and temperature-sensitive magnet 6 are contained in respectively on corresponding wheel hub tooth and the groove, and the design mechanism is simple, do not need complicated temperature transducer; reliable in action; good reproducibility can be used in the interior protection to integral body normal operation equipment of lathe and gear-box widely, can make castellated according to this this clutch of principle; friction type, or the magnet clutch of nominal torque.
