The purpose of this utility model is achieved through the following technical solutions: a kind of new mine product engaging and disengaging gear, comprise drive end part, Partner part and adjustment component, between this drive end part and Partner part, adjustment component is housed, it is characterized in that, described drive end part comprises drive end axle sleeve, external tooth wheel hub, supporting disk and external tooth friction disk, be bolted external tooth wheel hub between drive end axle sleeve and supporting disk, the inner peripheral surface of this external tooth wheel hub is connected with multiple external tooth friction disks spaced apart axially slidably; Described Partner part comprises Partner axle sleeve and internal tooth friction disk, the outer circumferential face of Partner axle sleeve leads to external tooth and is connected with multiple internal tooth friction disk, each internal tooth friction disk embeds in the gap of adjacent external tooth friction disk, and internal tooth friction disk and external tooth friction disk are arranged alternately.
Described adjustment component comprises adjusting screw rod, disc spring, disc spring briquetting and disc spring guide rod, adjusting screw rod is arranged in the screw of described drive end axle sleeve, one end of disc spring guide rod is against the outside of internal tooth friction disk or external tooth friction disk, multiple disc spring overlap is enclosed within disc spring guide rod, and the top of described adjusting screw rod is offseted by disc spring briquetting and outermost disc spring.
Described external tooth wheel hub is by being located at the internal tooth of inner circumferential surface and described external tooth friction disk external tooth setting-in.
Described Partner axle sleeve is by being located at the external tooth of radial flange outer circumferential face and described internal tooth friction disk internal tooth setting-in.
The utility model has the advantages that: rational in infrastructure, overload protection is reliable and secure, protects and the function of rope compensation, can be applicable to the multiple occasion such as underground coal mine, ground with common electric winch with the use of oil cylinder can be replaced to realize tension force.
Accompanying drawing explanation
Fig. 1 is axial sectional structure schematic diagram of the present utility model.
Embodiment
See Fig. 1, new mine product of the present utility model intelligence engaging and disengaging gear, its preferably embodiment as shown in Figure 1, comprise drive end part A, Partner part B and adjustment component C, between this drive end part A and Partner part B, adjustment component C is housed, it is characterized in that:
Described drive end part A comprises drive end axle sleeve 1, external tooth wheel hub 6, supporting disk 10 and external tooth friction disk 8, it is external tooth wheel hub 6 between the left side of drive end axle sleeve 1 and supporting disk 10, three is fastenedly connected mutually by bolt 9, the inner peripheral surface of this external tooth wheel hub 6 is connected with multiple external tooth friction disks 8 spaced apart by internal tooth, external tooth friction disk 8 can move axially relative to external tooth wheel hub 6, and can not relatively rotate.
Described Partner part B comprises Partner axle sleeve 11 and internal tooth friction disk 7, the outer circumferential face of Partner axle sleeve 11 leads to external tooth and is connected with multiple internal tooth friction disk 7, each internal tooth friction disk 7 embeds in the gap of adjacent external tooth friction disk 8, and internal tooth friction disk 7 and external tooth friction disk 8 are arranged alternately.Internal tooth friction disk 7 can slide axially relative to Partner axle sleeve 11, and can not relatively rotate.
