Transmission mechanism for magnetic refrigerator

Abstract

The invention discloses a transmission mechanism for a magnetic refrigerator. The transmission mechanism comprises a lead screw and a sliding block in screw thread fit with the lead screw, wherein the lead screw is connected and arranged between bases in a rotating mode through a bearing. The transmission mechanism further comprises a claw type packaging box and linear slide rails, wherein the linear slide rails are connected and arranged between the bases in parallel; the top end of the claw type packaging box is fixedly connected with the sliding block through a bolt; the two sides of the claw type packaging box are in sliding fit with the linear slide rails; motors driving the lead screw to rotate through a gear pair are arranged on the outer sides of the bases; U-shaped magnets are respectively arranged on the inner sides of the two ends of the bases. The transmission mechanism is simple and compact in structure and relatively low in cost; the transmission mechanism is stable in transmission and high in transmission efficiency, and linear reciprocating motion of the claw type packaging box can be realized; the claw type packaging box is of a claw type structure, so that the sliding block in the lead screw device can be mounted on the top of the claw type packaging box, so that the space is saved, and the claw type packaging box can be driven to enter a narrow space without being obstructed by the magnets; therefore, the transmission mechanism can be applied to working environments with narrow spaces.

Description

technical field [0001] The invention belongs to the technical field of machinery, in particular to a transmission mechanism for a magnetic refrigerator, which can realize the transmission device that converts the rotational motion of a motor into the reciprocating linear motion of a packaging box. Background technique [0002] As a high-tech green refrigeration technology, magnetic refrigeration has the following advantages compared with the traditional compression refrigeration cycle: (1) Environmental protection and pollution-free: the use of Freon and other refrigerants in the traditional compression refrigeration cycle has brought about the environmental problem of ozone layer destruction, Moreover, refrigerants such as ammonia, hydrocarbons, and freon have disadvantages such as poisonous, flammable, easy to leak, and explosive, and the magnetic refrigeration cycle is well overcome due to the use of magnetic refrigerants of solid materials and water as the heat exchange f...
