Description
Technical field
The utility model belongs to technical field of mechanical transmission, is specifically related to a kind of two ends reducing gear utilizing crank to link.
Background technique
On the product line of mechanical manufacturing field, needing a mechanical device only to do simple straight reciprocating motion sometimes can complete production.Solution general is at present, utilizes automatically controlled mechanical arm to carry out program control work.Although accuracy of manufacturing can ensure like this, device price is higher, improves cost of production, and long-time stability in use also can be subject to very large challenge, and maintenance is comparatively complicated.
Model utility content
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of two ends reducing gear utilizing crank to link, and its structure is simple, transmission efficient stable, and motion speed is adjustable, and repair demolition is convenient and with low cost.
For achieving the above object, the utility model adopts following technological scheme to be achieved:
The two ends reducing gear utilizing crank to link, comprises gear variable speed motor, transmission shaft, stationary platen, steering channel, guide rod, leader casing; Wherein, stationary platen is provided with two bearing supports, a bearing is provided with in each bearing support, transmission shaft is through the bearing in two bearing supports, and its one end is provided with belt wheel, and the other end is provided with crank, gear variable speed motor is connected with the belt wheel on transmission shaft by belt pulley, the external part of crank is slidably connected by the groove on roller and steering channel, and steering channel is set with and is fixed on guide rod, and the two ends of guide rod are set with two leader casings respectively and are connected.
The utility model further improves and is: one end of crank and transmission shaft is connected by key and keyway.
The utility model further improves and is: the fluting direction of steering channel upper groove is perpendicular to guide rod.
Compared with prior art, the utility model tool has the following advantages:
What the whole mechanism of the utility model adopted is common mechanical structure, and manufacture so convenient, cost is lower, good economy performance.The movement travel speed variability of guide rod in leader casing is by the structures shape of whole mechanism, less by external interference factor, so good stability.The output effect of mechanism is simple, and applicability is more extensive.
Therefore, the utility model structure is simple, and stable transmission is efficient, and the driving mechanism that motion speed is adjustable, can ensure accuracy of manufacturing, can reduce manufacture cost again, and easy to maintenance.

Fig. 2 is the plan view of the two ends reducing gear that the utility model utilizes crank to link;
Fig. 3 is the side view that guide rod and leader casing coordinate.
In figure, the implication of each label has: 1-gear variable speed motor, 2-transmission shaft, 3-stationary platen, 4-crank, 5-steering channel, 6-guide rod, 7-leader casing.
Embodiment
Below provide specific embodiment of the utility model, it should be noted that the utility model is not limited to following specific embodiment, all equivalents done on technical scheme basis all fall into protection domain of the present utility model.
As shown in Figure 1, a kind of two ends reducing gear utilizing crank to link of the utility model, comprises gear variable speed motor 1, transmission shaft 2, stationary platen 3, steering channel 5, guide rod 6, leader casing 7; Wherein, stationary platen 3 is provided with two bearing supports, in each bearing support, is provided with a bearing, transmission shaft 2 through the bearing in two bearing supports, by bearing just its smooth transfer power more during transmission shaft 2 transmission; One end of transmission shaft 2 is provided with belt wheel, the other end is provided with crank 4, gear variable speed motor 1 is connected with the belt wheel on transmission shaft 2 by belt pulley, the external part of crank 4 is slidably connected by the groove on roller and steering channel 5, the friction between crank 4 and steering channel 5 can be reduced like this, and then minimizing kinetic energy rejection, steering channel 5 is set with and is fixed on guide rod 6, and the two ends of guide rod 6 are set with two leader casings 7 respectively and are connected.
Further, crank 4 is connected by key and keyway with one end of transmission shaft 2.In addition, the fluting direction of steering channel 5 upper groove is perpendicular to guide rod 6, and roller can slide up and down in steering channel 5 upper groove, and steering channel 5 to be sleeved on guide rod 6 and can not relative sliding, and guide rod 6 and two leader casings 7 are set with and are connected and can relative sliding.
Above-mentioned integrated model motion speed can be regulated by gear variable speed motor 1, and the running speed of whole mechanism can be made to change within the specific limits, to realize best running speed.The speed variable of guide rod 6 in its whole movement travel, realizes accelerating in the middle of stroke, the conversion slowed down in two ends, effectively shortens the time of reciprocating stroke, increase work efficiency, so just can meet the usage requirement of special manufacturing machine.
In order to understand further the utility model, now an explanation is done to its working procedure:
As shown in Figure 1, first gear variable speed motor 1 rotates, transmission shaft 2 is driven to rotate in stationary platen 3 by belt pulley, and then order about crank 4 and rotate, then the roller end of crank 4 in steering channel 5 along approaching channel direction reciprocating rolling, roller moves in a circle around transmission shaft 2 simultaneously, and being sleeved in steering channel 5 due to guide rod 6 and relatively can not sliding, last steering channel 5 orders about guide rod 6 in leader casing 7, does the to-and-fro motion of slowing down at two ends.
