Utility model content
Technical problem to be solved in the utility model is: the drive mechanism providing a kind of penknife that penknife chip efficiency can be made to improve.
For solving the problem, the technical solution adopted in the utility model is: a kind of drive mechanism of penknife, comprise and being connected and the hob head of synchronous axial system with penknife handle, described hob head is provided with hobboing cutter and hobboing cutter gear, hobboing cutter gear is external tooth, the outer ring being positioned at hob head driving end is fixedly connected with a driven wheel, described driven wheel be external tooth and with hob head synchronous axial system, the outer ring of described hob head driving end is also provided with a rotatable hobboing cutter driven wheel and a travelling gear, described hobboing cutter driven wheel and travelling gear are connected to a fixed and synchronous axial system, described hobboing cutter driven wheel and travelling gear are internal tooth, described travelling gear and the diameter of travelling gear corresponding with the position of driven wheel is greater than the diameter of driven wheel, an idle pulley is at least fixedly installed between described travelling gear and driven wheel, described idle pulley coordinates with the internal tooth of travelling gear and the external tooth of driven wheel respectively, described hobboing cutter driven wheel and diameter of hobboing cutter driven wheel corresponding with the position of hobboing cutter gear on hob head is greater than the diameter of hobboing cutter gear, the internal tooth of described hobboing cutter driven wheel matches with the external tooth of hobboing cutter gear.
Preferably, two idle pulleys can be provided with between described travelling gear and driven wheel.
Preferably, described hobboing cutter driven wheel and travelling gear can be formed in one.
Preferably, described hobboing cutter driven wheel and travelling gear can also be coordinated by assembling.
Preferably, described penknife handle and hob head can be threaded connection.
The beneficial effects of the utility model are: the rotation of the utility model hobboing cutter driven wheel accelerates the geared speed of hobboing cutter gear and hobboing cutter driven wheel internal tooth, thus accelerates the rotation of hobboing cutter, therefore improve the chip efficiency of penknife, and structure is simple.

Detailed description of the invention
The utility model is further described by specific embodiment below in conjunction with accompanying drawing.
As shown in Figure 2, the drive mechanism of described a kind of penknife, comprise and being connected and the hob head 2 of synchronous axial system with penknife handle 1, penknife handle 1 described in the utility model is threaded connection with hob head 2, be threaded and install and manufacture homogeneous phase to convenient, described hob head 2 is provided with hobboing cutter 3 and hobboing cutter gear 4, hobboing cutter gear 4 is external tooth, the outer ring being positioned at hob head 2 driving end 21 is fixedly connected with a driven wheel 5, described driven wheel 5 be external tooth and with hob head 2 synchronous axial system, the outer ring of described hob head 2 driving end 21 is also provided with a rotatable hobboing cutter driven wheel 6 and a travelling gear 7, as shown in Figure 3, described hobboing cutter driven wheel 6 and travelling gear 7 are connected to a fixed and synchronous axial system, described hobboing cutter driven wheel 6 and travelling gear 7 are internal tooth, described travelling gear 7 and diameter of travelling gear 7 corresponding with the position of driven wheel 5 is greater than the diameter of driven wheel 5, an idle pulley 8 is at least fixedly installed between described travelling gear 7 and driven wheel 5, described idle pulley 8 coordinates with the internal tooth of travelling gear 7 and the external tooth of driven wheel 5 respectively, described hobboing cutter driven wheel 6 and diameter of hobboing cutter driven wheel 6 corresponding with the position of hobboing cutter gear 4 on hob head 2 is greater than the diameter of hobboing cutter gear 4, the internal tooth of described hobboing cutter driven wheel 6 matches with the external tooth of hobboing cutter gear 4, as shown in Figure 5.
The utility model does not do concrete restriction to the number of idle pulley 8, when preferentially selecting, be provided with two idle pulleys 8 between described travelling gear 7 and driven wheel 5, as shown in Figure 4, not only can not additionally increase too many cost but also the rotation of handle 3 can be made relatively lighter;
Hobboing cutter driven wheel 6 described in the utility model and travelling gear 7 can be formed in one, one-body molded easily manufactured, easy for installation; Also can be coordinated by assembling, after hobboing cutter driven wheel 6 and travelling gear 7 wherein have one to be damaged, only need change the gear of damage, need not change simultaneously, decrease maintenance and repair cost comparatively speaking; Concrete condition can be determined according to specific needs.
During use, penknife handle 1 rotates, hob head 2 rotates with penknife handle 1 together, hobboing cutter gear 4 now on hob head 2 just starts to revolve round the sun around the center of hob head 2, and constantly engage with the internal tooth of hobboing cutter driven wheel 6 simultaneously, therefore hobboing cutter gear 4 also starts rotation, thus drives hobboing cutter 3 to start to rotate, and now just starts chip; Meanwhile, when penknife handle 1 rotates, driven wheel 5 drives the reverse of travelling gear 7 by idle pulley 8, therefore hobboing cutter driven wheel 6 also starts to reverse, and now, the rotation of hobboing cutter driven wheel 6 accelerates the geared speed of hobboing cutter gear 4 and hobboing cutter driven wheel 6 internal tooth, thus accelerates the rotation of hobboing cutter 3, therefore improves the chip efficiency of penknife.
