Description
Technical Field
The utility model relates to a spur rack technical field specifically is a spur rack.
Background
The spur rack is a special gear with teeth distributed on the strip-shaped body. The rack is also divided into a straight rack and a helical rack which are respectively matched with a straight cylindrical gear and a helical cylindrical gear; the tooth profile of the rack is a straight line instead of an involute (a plane for the tooth surface), which is equivalent to a cylindrical gear with an infinite reference circle radius; the rack is a strip-shaped part matched with the gear. It is equal to a section of the periphery of a gear of infinite diameter. A plurality of teeth are uniformly distributed on one side, and are meshed with the gear to change rotation into movement or change movement into rotation. The rack is in a strip shape, one side of the rack is provided with teeth, and the rack can be regarded as a section of a gear with infinite diameter.
At present, the existing straight rack is inconvenient to install, low in structural strength, single-type gear teeth, only one gear can be used due to the single gear teeth, and the application range is narrow. Accordingly, a spur rack is provided to solve the problems set forth in the background art described above by those skilled in the art.

An object of the utility model is to provide a spur rack to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a spur rack, includes rack, the first teeth of a cogwheel, the second teeth of a cogwheel and fixed through hole, the rack upper end is provided with a plurality of first teeth of a cogwheel, rack upper end just is located first teeth of a cogwheel front side department and all is provided with the second teeth of a cogwheel, the first teeth of a cogwheel and the second teeth of a cogwheel all are parallel equidistant range at the rack.
As a further aspect of the present invention: the width of the first gear teeth is smaller than that of the second gear teeth, the length of the first gear teeth is larger than that of the second gear teeth, and the number of the first gear teeth is equal to that of the second gear teeth.
As a further aspect of the present invention: and a plurality of fixing through holes are symmetrically formed in the left side and the right side of the front end of the rack.
As a further aspect of the present invention: the rack is made of one of forged steel, cast steel or manganese steel.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses structural design is simple reasonable, convenient and fast uses, the practicality is very high, in operation, it can realize the fixed to the rack to run through fixing hole through fastening nut, and fixed convenient firm, outside gear is located the rack rear side can be connected with the meshing of first teeth of a cogwheel, realize the transmission, outside gear is located the rack front side can be connected with the meshing of second teeth of a cogwheel and realize the transmission, can realize the multi-purpose target of a straight-teeth rack from this, the practicality is better, and this device structural strength is big, wear-resisting, life is of a specified duration more.
