Abstract
The utility model discloses a structure for matching a winch main shaft and a transmission shaft, comprising a winch main shaft and a transmission shaft, wherein a boss is formed on the end face of the main shaft; a recess is formed in the end of the corresponding transmission shaft; the boss and the recess are matched; and the winch main shaft and the transmission shaft are connected. The boss is easy to process; the boss and the shafts can be processed together; the late finish machining is easier than the processing in the recess as well; relatively, the finish machining on the end face with the recess is more difficult; since the weight of the winch main shaft with a winding drum is very great and the shape is larger, a change is made, i.e. the boss is formed on the end face of the winch main shaft difficult to process, and the recess is formed on the end of the transmission shaft easier to process; if the production is performed according to the changed structure, the process flow is simpler; no other equipment is used; and moreover, the period is shortened, and the structure can be finished in the interior of a unit.
Description
Technical field
The utility model relates to a kind of structure of winch main shaft, specifically a kind of winch main shaft and transmission shaft fit structure.
Background technology
Winch is called again winch, mainly applies to build, material lifting or flat the dragging of hydraulic engineering, forestry, mine, harbour etc.
Prior art winch main shaft 1 is with shown in transmission shaft fit structure Fig. 2, offer groove 4 at main-axis end 2 end faces, transmission shaft 6 end faces are provided with boss 5, groove 4 matches with boss 5, as shown in Figure 1, for guaranteeing the precision of winch main 1, winch main 1 welds with reel 7 after prtreatment, and then carries out machinework.It is very heavy that winch main 1 adds both weight of coiling 7, and profile is larger, the inconvenience upset, especially main-axis end 2 grooves 4 interior bad processing, so structure of recessing 4 on the winch main shaft, this is so that the processing of main shaft end face is very inconvenient, and the process-cycle can be elongated, but also will process with different equipment.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of winch main shaft and transmission shaft fit structure, is convenient to the processing of main-axis end.
To achieve these goals, the technical solution adopted in the utility model is: a kind of winch main shaft and transmission shaft fit structure, comprise winch main shaft and transmission shaft, offer boss at the main-axis end end face, offer groove on the axle head of corresponding transmission shaft, boss matches with groove, and the winch main shaft links to each other with transmission shaft.
Be evenly equipped with some mounting holes on the winch main shaft end face, winch main shaft and transmission shaft are bolted.
Because processing boss ratio is easier to, can together process with axle, the later stage fine limit work is also than handling ease in groove, fine limit work is relatively more difficult on reeded end face relatively, and that winch main adds both weight of coiling is very heavy, profile is larger, so the utility model is changed on the winch main-axis end end face of processing difficulties and is offered boss, processing is relatively easy to offer on the transmission shaft end groove, produce by the structure after changing, so that technological process is fairly simple, need not change other equipment, and the cycle can shorten, just can finish at internal institution.
Description of drawings
Fig. 1 is the prior art structural representation;
Fig. 2 is prior art winch main shaft and transmission shaft fit structure scheme drawing;
Fig. 3 is the utility model structural representation.
Among the figure: 1, winch main shaft, 2, main-axis end, 3, centre hole, 4, groove, 5, boss, 6, transmission shaft, 7, reel.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 3, the utility model winch main shaft and transmission shaft fit structure comprise winch main shaft 1 and transmission shaft 6, offer boss 5 at main-axis end 2 end faces, offer groove 4 on the axle head of corresponding transmission shaft 6, boss 5 matches with groove 4, and winch main shaft 1 links to each other with transmission shaft 6.
Be evenly equipped with some mounting holes on winch main shaft 1 end face, winch main shaft 1 and transmission shaft 6 are bolted, and be for convenience detach.
