Abstract

Compared with the existing mechanical driving turbo-variable-pitch device, the utility model is characterized in that the utility model makes use of a pure mechanical driving and an overrunning clutch control to guide the power of the output end to the input end, to realize the energy feedback, to make the turbo-variable-pitch device completely penetrated under the condition of light load and high speed, to control the maximum speed of an output shaft, and to ensure that the turbo-variable-pitch device is arranged within the speed range of high efficiency under the condition of light load and high speed. The utility model has the advantages of energy saving, high safety, sensitive response, accurate speed limiting, simple structure, small shock, etc. The mechanical driving turbo-variable-pitch device is an ideal turbo-variable-pitch device and is suitable to the turbo-variable-pitch device in various industries; particularly, when the utility model is used on a machine with intermittent operation and frequent fluctuation load, the advantage is prominent.

Description

Mechanical driving turbo-variable-pitch device

The utility model relates to a kind of mechanical transmission hydrotransmitter that is used for industry-by-industry.

Background technique of the present utility model is: the torque-converters of selling on the present domestic and international market; because torque-converters has an efficient district scope; when heavy-duty low-speed or underloading high speed, all be in the work of poor efficiency district; not only waste lot of energy; and heat dissipation equipment that need be huge; during for heavy-duty low-speed; the situation that transmission efficiency is low, because load causes greatly, this situation is seldom; and people utilize the bending moment principle of torque-converters to obtain big output torque; overcoming the load of unexpected increase, and can protect the safety of equipment, also is useful even efficient is hanged down; during for the underloading high speed; the situation that transmission efficiency is low is not desirable just, and unfavorable to the safety of equipment; in order to solve this shortcoming, commonly used at present have three kinds of methods:

First method is to adopt the method for filling oil extraction, but this method response speed is slow, fill oil extraction individual process to be arranged, need artificial operation again, automatically fill discharge equipment even mix, not only damage easily, and response speed still can not solve slowly, and under the condition for the frequent changeable or discontinuity work of load, effect is undesirable.

Second method adopts the adjusting vane formula, and this method reflection is sensitive, but needs artificial operation, even mix automatic control tegulatingdevice, still damages easily, and complex structure can not well address this problem.

The third method adopts turbine and pump impeller enclosed type, but the critical speed of rotation instability during this method locking, and the output shaft rotating speed occurs and take place to change suddenly, and produce and impact, still not a kind of desirable method.

The purpose of this utility model is: adopt pure mechanically operated method, utilize the torque-converters self characteristics, provide a kind of reflection sensitive, simple in structure, long service life, safe and reliable, do not need artificial operation, realize its function automatically, impact little, can guarantee that hydrotransmitter is when the underloading high speed or when being interrupted work, the long-term torque-converters that keeps is efficiently distinguished work in the scope, can save a large amount of energy, and reduce heat dissipation equipment.

Above-mentioned purpose of the present utility model is to realize in order to following method, its special way is the power of output terminal is paid by gear transmission, free wheel device, transmission shaft causes input end, make the impermeability or the slight transmissibility of torque-converters, instantaneous become (Fig. 1) fully thoroughly when a certain rotating speed, power engine is worked under light load, its organization plan is: the mechanical transmission hydrotransmitter, the gear that gear transmission is paid in (6) is connected with the output shaft (3) of hydrotransmitter (2), another gear sky is enclosed within on the transmission shaft (5), sky be enclosed within on the transmission shaft (5) gear with the axle between adopt free wheel device (4) to be connected, gear pair (7) is contained in respectively on the input shaft (1) and transmission shaft (5) of hydrotransmitter (2).

The utility model is compared with background technique, the one owing to adopted pure mechanical transmission feedback mechanism, thus have safe and reliable, the life-span long, non-damageable advantage; The 2nd, owing to having adopted the work of free wheel device Control and Feedback mechanism, relative velocity is very little when locking, thereby has the advantage that reflection is sensitive, accurate, impact is little; The 3rd, owing to adopted free wheel device control, thereby do not need artificial operation, realize its function automatically; The 4th, simple in structure, easy manufacturing, easy to maintenance; The 5th, can limit the highest output speed and the minimum efficiency point of hydrotransmitter accurately by changing the velocity ratio that gear transmission is paid, the safety of protection equipment; The 6th, energy saving reduces heat dissipation equipment, when load is zero, can save 75～80% energy, and is obvious especially to the mechanical advantage of being interrupted work; The 7th, because the maximum speed of torque-converters is limited in a certain numerical value, make the mechanical transmission of back require the contradiction between heavy load and the limit speed to reduce.

In sum, the utility model relates to a kind of mechanical transmission hydrotransmitter that is used for industry-by-industry, adopt the energy feedback method, realize torque-converters by pure mechanical transmission, becoming when the underloading high speed fully can be thoroughly, energy saving, safe and reliable, reflection is sensitive, speed limit is accurate, simple in structure, it is little to impact, and is a kind of desirable hydrotransmitter, is adapted to the industry-by-industry hydrotransmitter, especially for the machinery that is interrupted work, advantage is more outstanding.
