Abstract
The utility model relates to a single stage, large speed ratio cycloid retarding mechanism, which comprises pin wheel housing, a gear pin, a cycloid gear and an eccentric bearing. The utility model is characterized in that by improving number of cycloid gear and employing gear shaping method, the precision and quality of the cycloid gear and the pin wheel housing. The utility model is mounted inside the first level cycloid retarding mechanism, which is a substitution for the well known two stages cycloid retarding mechanism of 89-149 large speed ratios, and reduces volume, saves material, decreases cost and improves bearing capacity of the retarding mechanism.
Description
Technical field
The utility model belongs to the deceleration component of speed reducer, particularly relates to a kind of cycloid speed reducer structure of single-stage large speed ratio.
Background technique
At present, domestic known X series cycloid speed reducer, its general structure is made up of input block, deceleration component and output block three parts.Wherein one-level (being single-stage) speed ratio is 1: 87 to the maximum.If desired greater than the speed reducer of speed ratio 87, just must adopt the two-stage collocation to form, and on speed ratio, have certain narrow limitation, in addition, also increase the boundary dimension of speed reducer, promptly increased the volume of speed reducer, increased the input and the machining period of material, its cost is increased, benefit reduces.
Summary of the invention
The utility model provides a kind of cycloid speed reducer structure of single-stage large speed ratio for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of cycloid speed reducer structure of single-stage large speed ratio, form by pin wheel housing, gear pin, cycloid wheel and capacity eccentric bearing, the endoporus of cycloid wheel is moving to be contained on the capacity eccentric bearing, it is characterized in that: the interior circle of pin wheel housing is evenly distributed with 45-75 semicircle orifice, wherein, rotatable gear pin all is housed in each semicircle orifice, is evenly distributed with 89-149 the gear teeth on the excircle of cycloid wheel, the gear pin in the gear teeth meshing pin wheel housing of cycloid wheel in first circular hole of circle.
Advantage and the good effect that the utlity model has are: the utility model is need be greater than the speed reducer of speed ratio 87, and in order to dwindle the volume of speed reducer, do not adopt under the situation of double reduction again, promptly adopt the number of teeth that increases cycloid wheel and the pin number of teeth that increases pin wheel housing, because of the internal diameter circumference of pin wheel housing is limited, this necessity of making use of momentum reduces the diameter of gear pin, for many years, old technology to processing small holes adopts boring, reams always is difficult to reach the requirement of design accuracy.Because development of technology adopts the gear shaping generating method to process a plurality of uniform apertures, both solved the low difficult problem of precision at present, and improved manufacturing efficiency again greatly, the speed ratio of cycloid speed reducer single-stage is further improved, now, slowest ratio can reach 149.Can replace a part of double reduction machine like this, promptly available one-level large speed ratio replaces in the past that speed ratio is the double reduction machine of 89-149.Thereby reduced the part of first class reducer, dwindled axial dimension, reduced volume, saved material, reduced cost.And in the running of speed reducer, because increasing of total number of teeth in engagement relatively reduced the contact strength of the flank of tooth, so the bearing capacity of speed reducer is further enhanced.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, the utility model belongs to the deceleration component of cycloid speed reducer, is made up of pin wheel housing 1, gear pin 2, cycloid wheel 3, capacity eccentric bearing 4.The endoporus of cycloid wheel 3 is moving to be contained on the capacity eccentric bearing 4, so that cycloid wheel 3 forms the eccentric gearing structure, the interior circle of pin wheel housing 1 is evenly distributed with 61 semicircle orifices, rotatable gear pin 2 wherein all is housed in each semicircle orifice, be evenly equipped with 121 gear teeth on the excircle of cycloid wheel 3, gear pin 2 in the gear teeth of cycloid wheel 3 and the pin wheel housing 1 in first circular hole of circle is meshed, and the transmission by capacity eccentric bearing 4, cycloid wheel 3 is evenly slowed down rotate.
The power of input drives cycloid wheel 3 by capacity eccentric bearing 4 and rotates and swing, a part of gear pin 2 in the gear teeth meshing pin wheel housing 1 of cycloid wheel 3 in first circular hole of circle, cycloid wheel 3 is slowly run, and the guide, the bearing pin that install in uniform 10 circular holes on the intermediate circumference by cycloid wheel 3, with the low speed of cycloid wheel 3, big torque output.
The utility model is contained in the one-level cycloid speed reducer, and can replace known large speed ratio is 89 to 149 two-stage cycloid speed reducer, and can shorten axial dimension, reduces volume, saves material, reduces cost, and improves the bearing capacity of speed reducer.
