Abstract
The utility model discloses a fan-shaped gear constant-speed reciprocating mechanism. The fan-shaped gear constant-speed reciprocating mechanism comprises a base, a work table and fan-shaped gears. The work table is provided with a first rack and a second rack. The fan-shaped gears are arranged on the base and between the first rack and the second rack, and can be meshed with the first rack and the second rack. According to the fan-shaped gear constant-speed reciprocating mechanism, when the fan-shaped gears are meshed with the first rack, the first rack drives the work table to move in one direction, and when the fan-shaped gears are meshed with the second rack, the second rack drives the work table to move in an opposite direction. Due to the facts that the upper ends and the lower ends of the gears are opposite in rotation direction and identical in linear speed, the constant-speed reciprocating motion of the work table can be achieved.
Description
Technical field
The utility model belongs to the technical field of transmission device.
Background technique
Current reciprocating mechanism the most often selects fourbar linkage, but fourbar linkage is in the time carrying out transmission, has the characteristics such as urgency is returned, dead point, can not carry out the transmission of average rate.But in the time of some production and processings, need to carry out average rate to-and-fro motion, as continued to adopt fourbar linkage, just can not reach production and processing requirement.We need a kind of simple in structure, average rate to-and-fro motion that transmission is stable.
Model utility content
The utility model provides a kind of fan tooth constant speed reciprocating mechanism, the problem that can not carry out average rate transmission to solve existing reciprocating mechanism.
In order to solve the problems of the technologies described above, the utility model provides following technological scheme: a kind of fan tooth constant speed reciprocating mechanism, comprise pedestal, worktable and fan type tooth, worktable is provided with the first tooth bar and the second tooth bar, fan type tooth is arranged on pedestal, gear is between the first tooth bar and the second tooth bar, and fan type tooth can engage with the first tooth bar and the second tooth bar.
Compared with prior art, the utility model has the advantage of: in the time that fan type tooth engages with the first tooth bar, the first rack drives worktable moves along a direction; In the time that fan type tooth engages with the second tooth bar, the second rack drives worktable moves along contrary direction.Because top and bottom switched in opposite and the linear velocity of gear are identical, therefore can realize the average rate to-and-fro motion of worktable.
Further, a side of described fan type tooth is provided with groove, and another side is provided with the projection of mating with groove.Multiple fan type teeth can be linked together by groove and projection, form the fan type tooth of different sizes, thus the mobile range of adjusting operating platform.
Brief description of the drawings
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
Fig. 1 is the structural representation of the utility model fan tooth constant speed reciprocating mechanism for implementing example.
Reference character in Figure of description comprises: 1, pedestal; 2, worktable; 3, fan type tooth; 4, the first tooth bar; 5, the second tooth bar; 6, groove; 7, projection; 8, temperature transducer.
Embodiment
As shown in Figure 1, a kind of fan tooth constant speed reciprocating mechanism in the present embodiment, comprise pedestal 1, worktable 2 and fan type tooth 3, worktable 2 is provided with the first tooth bar 4 and the second tooth bar 5, fan type tooth 3 is arranged on pedestal 1, gear is between the first tooth bar 4 and the second tooth bar 5, and fan type tooth 3 can engage with the first tooth bar 4 and the second tooth bar 5.One side of described fan type tooth 3 is provided with groove 6, and another side is provided with the projection 7 of mating with groove 6, on fan type tooth 3, is also provided with temperature transducer 8.
The present embodiment engages with the first tooth bar 4 and the second tooth bar 5 respectively by fan type tooth 3, thereby drives worktable 2 to-and-fro motion.When installation, 2 fan type teeth 3 can be used in combination, but be noted that 2 fan type teeth 3 can not engage with the first tooth bar 4 and the second tooth bar 5 simultaneously.
For a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some distortion and improvement, these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
Claims (2)
1. a fan tooth constant speed reciprocating mechanism, comprise pedestal and worktable, it is characterized in that: also comprise fan type tooth, worktable is provided with the first tooth bar and the second tooth bar, fan type tooth is arranged on pedestal, gear is between the first tooth bar and the second tooth bar, and fan type tooth can engage with the first tooth bar and the second tooth bar.
