Abstract

The utility model discloses a ground trowelling machine. The machine top is provided with an internal combustion engine (1), an output shaft of the internal combustion engine (1) extends downward to be connected with a speed shifting mechanism. An output shaft (4) of the speed shifting mechanism extends downward to be fixedly assembled with a grinding disc (5). The speed shifting mechanism is a two-stage or more than two-stage speed shifting mechanism formed by that at least two pairs of straight gears are made a transmission fit. The prior similar products all need commutation components. The structure of the utility model does not need the commutation component any more, is easier to process and manufacture, improves the transmission efficiency, decreases the abrasion of the transmission component, and ensures that the manufacture and use cost are both decreased.

Description

A kind of terrace trowelling machine
Technical field
The utility model relates to a kind of terrace trowelling machine, particularly a kind of terrace trowelling machine that adopts internal combustion engine as engine, and it comprises internal combustion engine, gear and mill.
Background technology
Adopt internal combustion engine in its power transmission process, all to need to drive the grinding of mill realization in the market to terrace through commutation as the terrace trowelling machine of engine; Its structure is that the power shaft of output shaft by belt transmission and gear of internal combustion engine is in transmission connection, and the output shaft of gear stretches out downwards with mill and fixedly is assembled together.Owing to need through commutation parts transferring power, unavoidably be subjected to the commutating restriction of parts of the transmission efficiency of this terrace trowelling machine.This type of terrace trowelling machine is to adopt worm and gear as its parts that commutate in the market, and the commutation parts that comprise worm and gear are compared spur gear and it is low to explain in words efficiency of movement, the energy consumption height; The wearing and tearing of the following commutation of same in addition working condition parts are also bigger, thereby make the allowance for depreciation of product higher.Aspect processing and fabricating, comprise that the commutation component processing manufacture craft of worm and gear is compared the spur gear complexity, cost is also higher.
The utility model content
The technical problems to be solved in the utility model provides a kind of transmission efficiency is higher, cost the is lower employing internal combustion engine terrace trowelling machine as engine.
For solving the problems of the technologies described above, the utility model is equipped with internal combustion engine at the machine top, and its output shaft stretches out downwards with gear and is in transmission connection, and the output shaft of gear stretches out downwards with mill and fixedly is assembled together.Above-mentioned gear is to cooperate the two-stage that constitutes or the gear more than the two-stage by at least two pairs of spur gear transmissions.
As a kind of improvement of the present utility model, what internal combustion engine adopted is gasoline engine.
As further improvement of the utility model, gear of the present utility model adopts following two-stage speed changing structure: described gear comprises two pairs of spur gears and the power shaft and the power transmission shaft that are parallel to each other, and the steamboat of first pair of spur gear is fixedly mounted on the power shaft of gear; The steamboat of the bull wheel of first pair of spur gear and second pair of spur gear is fixedly mounted on the power transmission shaft; The axle of the bull wheel of second pair of spur gear is as the output shaft of gear.
As another kind of improvement the of the present utility model, gear of the present utility model adopts following three-step gear shift structure: described gear comprises three pairs of spur gears and two power transmission shafts, and two power transmission shafts all parallel with power shaft; The steamboat of first pair of spur gear is fixedly mounted on the power shaft of gear; The steamboat of the bull wheel of first pair of spur gear and second pair of spur gear is fixedly mounted on first power transmission shaft; The steamboat of the bull wheel of second pair of spur gear and the 3rd pair of spur gear is fixedly mounted on second power transmission shaft of power transmission shaft, and the axle of the bull wheel of the 3rd pair of spur gear is as the output shaft of gear.
As further improvement of the utility model, the output shaft of the internal combustion engine while is as the power shaft of gear in the utility model.
Adopt structure of the present utility model, the output shaft of internal combustion engine stretches out downwards, makes gear no longer need to realize commutation function, thereby no longer needs commutation parts such as worm and gear necessary in the like product in the past, and only needs spur gear to realize speed changing function.The transmission efficiency of spur gear is than commutation parts height, and like product can reduce the power of product under identical working condition thereby make the utility model compare in the past, thereby reaches energy-conservation effect.Simultaneously, spur gear is simpler than commutation such as worm and gear, bevel gear parts on processing and fabricating, and cost is lower, so the utility model has also reduced cost than like product in the past.The spur gear degree of wear in use is littler than the degree of wear of commutation parts, compares the allowance for depreciation that can reduce product with the like product that adopts the commutation parts, thereby reduces use cost.Adopt gasoline engine to make the utility model be easy to realize that good applicability is arranged.Adopt the two-stage gear that the advantage of compact conformation is arranged, adopt three-stage speed change mechanism then can under the constant situation of gearratio, reduce the loss of gear.As the power shaft of gear, such the utility model that is arranged so that has been saved parts to the output shaft of internal combustion engine, and is more compact on the structure simultaneously, easier processing and fabricating, and these have all reduced cost.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2.
The specific embodiment
The utility model is equipped with gasoline engine 1 at the machine top as shown in Figure 1, and the output shaft of gasoline engine 1 stretches out downwards and simultaneously as the power shaft 2 of gear.The output shaft 4 of gear stretches out downwards with mill 5 and fixedly is assembled together.
Fig. 1 is the structural representation of the utility model embodiment 1, and its gear is to cooperate the two-stage gear that constitutes by two pairs of spur gear transmissions.Power shaft 2 and power transmission shaft 3 are parallel to each other, the steamboat 7 of first pair of spur gear is fixedly mounted on the power shaft 2, the bull wheel 8 of first pair of spur gear and the steamboat 9 of second pair of spur gear are fixedly mounted on the power transmission shaft 3, and the axle of the bull wheel 10 of second pair of spur gear is as the output shaft 4 of gear.
Fig. 2 is the structural representation of the utility model embodiment 2, and its gear is to cooperate the three-stage speed change mechanism that constitutes by three pairs of spur gear transmissions.Wherein power shaft 2 and power transmission shaft 3, power transmission shaft 6 are parallel to each other, the steamboat 7 of first pair of spur gear is fixedly mounted on the power shaft 2, the bull wheel 8 of first pair of spur gear and the steamboat 9 of second pair of spur gear are fixedly mounted on the power transmission shaft 3, the steamboat 11 of the bull wheel 10 of second pair of spur gear and the 3rd pair of spur gear is fixedly mounted on the power transmission shaft 6, and the axle of the bull wheel 12 of the 3rd pair of spur gear is as the output shaft 4 of gear.
