Abstract
The utility model discloses a fixed axle type gear transmission box, comprising a box body (6), a cover (8), an input gear shaft (9) and an output gear shaft (4), wherein the input gear shaft (9) and the output gear shaft (4) are coaxially and respectively arranged on the box body (6) via a bearing (5), the output end of the input gear shaft (9) is provided with an input gear (2), the input end of the output gear shaft (4) is provided with an output gear (3), the box body (6) via the bearing (5) is provided with a duplex gear (7) whose rotation shaft is parallel with the input and the output gear shafts (9, 4), the large gear of the duplex gear (7) is meshed with the input gear (2) and the small gear is meshed with the output gear (3). The aforementioned structure can resolve the gravity deflection defect of the machine, having the advantages of reasonable structure, simple operation, high transmission efficiency and uniform axis centers of the input and the output gear shafts.
Description
Technical field
The utility model relates to a kind of transmission device, particularly a kind of gear that is used on ground auger and the ice driller.
Background technique
At present, domestic common small-sized ground auger and ice driller generally adopt put-put as power, and transmission decelerating device adopts worm gear, worm drive, drives drilling tool work again by worm gear, worm drive; The deficiency of its existence is: owing to worm gear, worm drive are slowed down, power input shaft and output shaft can not be arranged on same axle center, cause machine center obviously to depart from the drilling tool center, when probing, will certainly cause drilling tool to depart from, so not only reduce transmission efficiency and probing precision, and cause user's operating difficulties; For this reason, manufacturer and knowledgeable people have carried out R and D at the problems referred to above, but do not have better products to come out so far as yet.
Summary of the invention
For solving the problem that above-mentioned transmission decelerating device exists, the purpose of this utility model provide a kind of simple and reasonable, easy to operate, transmission efficiency is high, the fixed shaft type gear of input output axle center unanimity.
The technological scheme that its technical problem that solves the utility model adopts, it comprises transmission case body, transmission-case cover, input gear shaft, output gear shaft, transmission-case cover is fixed on the transmission case body, described input gear shaft and output gear shaft are separately positioned on the transmission case body by bearing and are on the same axle center, the output terminal of input gear shaft is provided with the input gear, and the input end of output gear shaft is provided with output gear; Be provided with duplicate gear by bearing on the described transmission case body, the rotatingshaft of duplicate gear be arranged in parallel with input gear shaft and output gear shaft, the gearwheel of duplicate gear and input gear engagement, the small gear of duplicate gear and output gear engagement.
For the ease of being connected with put-put, the input end of described input gear shaft is fixedlyed connected with clutch disk.
After adopting said structure, following advantage and effect are arranged: the one, because input gear shaft and output gear shaft are on the same axle center, can guarantee that the petrol engine axle center is consistent with the drilling tool axle center, make machine center not depart from the drilling tool axle center, help operator's control, can improve borehole accuracy simultaneously.The 2nd, owing to adopt gear graduation to replace worm gear, worm screw speed change, can effectively improve the transmission efficiency of transmission case.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Shown in Figure 1, specific embodiments for the utility model fixed shaft type gear, it comprises transmission case body 6, transmission-case cover 8, input gear shaft 9, output gear shaft 4, transmission-case cover 8 is fixed on the transmission case body 6, described input gear shaft 9 and output gear shaft 4 are separately positioned on the transmission case body 6 by bearing 5, input gear shaft 9 and output gear shaft 4 are on the same axle center, the output terminal of input gear shaft 9 is provided with input gear 2, the input end of input gear shaft 9 is fixedlyed connected with clutch disk 1, and the input end of output gear shaft 4 is provided with output gear 3; Be provided with duplicate gear 7 by bearing 5 on the described transmission case body 6, the rotatingshaft of duplicate gear 7 be arranged in parallel with input gear shaft 9 and output gear shaft 4, the gearwheel of duplicate gear 7 and 2 engagements of input gear, the small gear of duplicate gear 7 and output gear 3 engagements.
The torque of put-put passes to input gear 2 by clutch disk 1, input gear shaft 9 during the utility model work, input gear 2 drives the gearwheel of duplicate gear 7, the small gear of duplicate gear 7 drives output gear 3, output gear 3 drives output gear shaft 4 and drilling tool rotary work, like this, both realized the requirement of gearing down, reach again simultaneously input gear shaft 9, output gear shaft 4 in same axle center, the unswerving purpose of machine center.
Claims (2)
1, a kind of fixed shaft type gear, comprise transmission case body (6), transmission-case cover (8), input gear shaft (9), output gear shaft (4), it is characterized in that: described input gear shaft (9) and output gear shaft (4) are separately positioned on the transmission case body (6) by bearing (5) and are on the same axle center, the output terminal of input gear shaft (9) is provided with input gear (2), and the input end of output gear shaft (4) is provided with output gear (3); Described transmission case body (6) is gone up and is provided with duplicate gear (7) by bearing (5), the rotatingshaft of duplicate gear (7) be arranged in parallel with input gear shaft (9) and output gear shaft (4), the gearwheel of duplicate gear (7) and input gear (2) engagement, the small gear of duplicate gear (7) and output gear (3) engagement.
2, fixed shaft type gear according to claim 1 is characterized in that: the input end of described input gear shaft (9) is fixedlyed connected with clutch disk (1).
