Abstract

The utility model relates to a quaternary reduction gear, which comprises a box body; the box body adopts an integral two-box structure; an input deceleration part is mounted in the first box; and an output deceleration part is mounted in the second box. The quaternary redactor adopting the integral two-box structure has the advantages of reasonable design of the box body and reasonable arrangement of transmission chains; and the transmission ratio reaches1 to 30; the tertiary deceleration is achieved in the first box, so that the structure of a reduction gearbox is extremely compact and reasonable. The quaternary reduction gear has the characteristics of large transmission ratio, great output power, simple installation, stable transmission and strong anti-impact force; meanwhile, the design principles are advanced, so that the quaternary reduction gear can be manufactured by ordinary equipment, the manufacture is simple, and the processing cost is low; and the utility model is suitable for reduction gears providing corresponding power input for large or medium sized stirrers or stirring plants.

Description

The level Four retarder

[technical field]

The utility model belongs to the retarder technical field, and relating to a kind of is that large and medium-sized stirrer (station) provides the power input, and then replaces the planetary bevel gear retarder of same function and the level Four retarder of cycloidal-pin wheel retarder.

[background technique]

Go up the speed reducer that uses at large and medium-sized stirrer (station), it must possess and have: one has than the big retarding ratio, and two have bigger output power, and the 3rd, limited installing space, characteristics such as the equilibrium of having ideals, morality, culture, and discipline reduction of speed, strong shock resistance.The large and medium-sized of early development or introduction built on the machine at home, major part is to adopt the import deceleration system, main retarder has planet umbrella tooth retarder, cycloidal-pin wheel retarder, helical gear-conic reducer etc., the technology of these retarders is all very complicated, process all very difficult, need to be equipped with,, need ten thousand yuan of 2-4 as a 30Kw planet umbrella retarder so cost an arm and a leg with ad hoc.Continuous introduction along with technology and equipment, these retarders can domesticize, but still need specialized factory, could produce with special device, price is still high, therefore presses for the exploitation big speed ratio, big output power, the reduction of speed equilibrium, the common cylinder gear reducer of strong shock resistance.General cylinder gear speed reducer has only three grades of decelerations, and velocity ratio is less.If obtain bigger velocity ratio, adopt the horizontal triaxial cylinder gear speed reducer, the external form volume of retarder is very huge, the waste wide variety of materials, the cost of production height, and need large-sized processing equipment and could make production.

[model utility content]

In order to overcome the above-mentioned shortcoming of prior art, it is a kind of for large and medium-sized stirrer (station) provides supporting power input speed reducer that the utility model provides, and have bigger velocity ratio, output power big, simple and easy, stable drive is installed, anti-impact force is strong and processing cost is hanged down the level Four retarder of characteristics.

The technological scheme that its technical problem that solves the utility model adopts is: a kind of level Four retarder, casing is arranged, and this casing is one two end structures, and the input deceleration part is housed in first railway carriage or compartment, and the output deceleration part is housed in second railway carriage or compartment.

In described input deceleration part, motor gear is meshed with the driving wheel of first order reduction gear, the driving wheel of the follower of first order reduction gear and second level reduction gear is meshed with shaftgear I respectively, the driving wheel of the follower of second level reduction gear and third level reduction gear is meshed with shaftgear II respectively, and the follower of third level reduction gear is meshed with shaftgear III.

Described output deceleration part is a fourth stage speed reducer, and the output gear of fourth stage speed reducer is meshed with shaftgear III.

The beneficial effects of the utility model are: adopt the level Four retarder of one two end structures, and the appropriate design of casing and the reasonable Arrangement of Transmitted chains, its ratio reaches 1: 30, just finishes three grades of decelerations in first railway carriage or compartment, makes the structure of speed reducer very compact, reasonable; Have that velocity ratio is big, output power is big, it is simple and easy to install, stable drive, characteristics that anti-impact force is strong, simultaneously because the design principle advanced person, fully can be by conventional equipment production, make simple and easyly, processing cost is low; Be well-suited for large and medium-sized stirrer (station) supporting power input speed reducer is provided.

[description of drawings]

Fig. 1 is a structural representation of the present utility model;

Among the figure: 1-motor gear, 2-first order reduction gear, 3-shaftgear I, 4-second level reduction gear, 5-shaftgear II, 6-third level reduction gear, 7-shaftgear III, 8-output gear, 9-casing.

[embodiment]

Below in conjunction with drawings and Examples the utility model is further specified:

Referring to Fig. 1, a kind of level Four retarder has casing 9, and this casing 9 is one two end structures, and the input deceleration part is housed in first railway carriage or compartment, and the output deceleration part is housed in second railway carriage or compartment; Each grade reduction gearing has driving wheel and follower.These casing 9 designing requirements are very compact, rationally, should consider the feasibility of processing, consider the formulation of assembly technology again, also to consider supporting installation with complete machine.

In described input deceleration part, motor gear 1 is meshed with the driving wheel of first order reduction gear 2, the driving wheel of the follower of first order reduction gear 2 and second level reduction gear 4 is meshed with shaftgear I3 respectively, the driving wheel of the follower of second level reduction gear 4 and third level reduction gear 6 is meshed with shaftgear II5 respectively, and the follower of third level reduction gear 6 is meshed with shaftgear III7; Finish three grades of decelerations by motor gear 1 to third level reduction gear 6, utilize first railway carriage or compartment of speed reducer just to finish three grades of decelerations, make the structure of speed reducer very compact, reasonable.

Described output deceleration part is a fourth stage speed reducer, and the output gear 8 of fourth stage speed reducer is meshed with shaftgear III7.

The utility model is broken through the traditional design thinking, optimizes the kind of drive, improves transmission efficiency, is a technological innovation of retarder industry.Adopt the utility model technology, the special Gear Reducer Optimal of big retarding ratio can be become common cylinder structure retarder; Can only become the simple and easy cylinder gear speed reducer that just can process with conventional equipment by professional production producer, the special Gear Reducer Optimal of producing with production equipment special, processing cost reduces greatly, so market prospects are wide.
