Abstract
The utility model relates to an automatic speed changer with a differential chain planet. The utility model is composed of a box body, a driving shaft, etc., comprising a speed changer and a differential mechanism, wherein, the differential mechanism is composed of two cylindrical gears are arranged on a planetary carrier and two sprocket gears which are mutually matched; the automatic speed changer is composed of a pair of cylindrical gears arranged on the planetary carrier and a pair of non-circular gears. The utility model has the advantage that the utility model has simple structure and large range of transmission ratio, and can obtain the purposes of high speed, safety and convenience and no damage on working mechanisms when the utility model is used for petroleum machinery.
Description
The utility model is the automatic transmission that a kind of chain planet differential is formed, and the last shackle working machine that is applied to products such as tubing in the petroleum industry, pump class, instrument class needs simple in structure, the automatic speed changing of safety easily and fast.Belong to mechanical engineering field.
The shackle working machine that uses on oil drilling at present as GYQ-560 type tubing tongs, is that a kind of high and low shift rotating speed is handled speed change gear with shift fork by gear change hand lever and double speed is even taken turns meshing conversion.U. S. Patent 4,348,920 disclose shackle working machine on a kind of drilling well tubing string, and this machine is to adopt hydraulic pressure, and mechanical mechanism successively clamps tubing string with different rotary speed workings, and it is the electric consumer sequence control that conversion clamps.In these prior aries, all the deficiency of Cun Zaiing is: velocity ratio has a peaceful scope, big in load change, change frequent and don't be convenient to shut down speed change occasion under, can't realize automatic stepless speed change.
The purpose of this utility model is just in order to solve deficiency of the prior art, and proposed the automatic transmission that a kind of chain planet differential is formed.Be applicable to that load change is frequent, be not easy to holdback clutch, or occasion such as the speed change that is not easy to stop, help to realize with movingization operation.
The purpose of this utility model is achieved in that
The automatic transmission that the chain planet differential is formed is made up of casing, transmission shaft etc., comprises speed changer and differential mechanism two-part, wherein differential mechanism by be installed on the planet carrier two cylindrical gears with two mutually the chain gear of interworking gold form; Automatic transmission is made up of a pair of cylindrical gear and a pair of noncircular gear that are installed on the planet carrier.
The purpose of this utility model can also be further perfect by following steps:
Planet carrier in the automatic transmission that the chain planet differential is formed is connected with the planet axis axle; Gear on the speed changer is a pair of speed change gear; Restriction minimum speed gear matches with the ratchet that can throw off; Be equipped with a snail volume or torsion spring on the speed change gear.
The utility model has 3 width of cloth accompanying drawings, and wherein Fig. 1 is a most preferred embodiment of the present utility model, also can make the accompanying drawing of specification digest.
Fig. 1, be structural drawing of the present utility model;
Fig. 2, be the differential design schematic representation in the utility model;
Fig. 3, be the speed changer structure schematic representation in the utility model.
The utility model compared with prior art has following advantage: simple in structure, gear range is big, Applied range can reach when being used for petroleum machinery fast, safety, convenience, not damage Working mechanism Purpose.
Below in conjunction with accompanying drawing most preferred embodiment of the present utility model is described further.
Most preferred embodiment of the present utility model as shown in Figure 1, the automatic transmission that the chain planet differential is formed, form by casing, transmission shaft etc., comprise speed changer and differential mechanism two-part, wherein differential mechanism is made up of 3,4 and two chain gear that cooperatively interact 1,2 of two cylindrical gears that are installed on the planet carrier 9; Automatic transmission is made up of a pair of cylindrical gear 5,6 and a pair of noncircular gear 7,8 that are installed on the planet carrier 9.Planet carrier 9 is connected with 10 of planet axis; Gear 7 and 8 is a pair of speed change gear; Gear limits minimum speed 12,13 matches with the ratchet that can throw off 11; Be equipped with a spring 14 on the speed change gear 7,8.
When gear 8 rotates to the semi major axis engaging position, be in the self-locking zone with gear 6, planet carrier 9, velocity ratio i=1, when the driven shaft moment of torsion increases, spring 11 on the gear 7 is further actuated, and what make 8 cycles of gear crosses the self-locking section, and the planet axis revolution adds rotation again, planet carrier 9 relatively rotates, and velocity ratio i is just along with the situation of change in torque takes place by corresponding the variation; Gear 12, gear 13 are a pair of pick-off gears, can control the minimum speed of driven shaft, when the load peak value is of short duration, can not adorn this a pair of gear, or ratchet thrown off, output speed can drop to very low even to 0, thereby satisfies the Maximum Torque requirement at place, load peak, and a whole set of parts can not damage because of overload.
Velocity ratio Applicable scope i=1 of the present utility model～500; Use power is unrestricted.
Manufacture and design this machine, can be energy development, lifting transportation, mechanical engineering field and provide simple in structure, gear range is big, helps to realize operation automation, saves the energy, increases work efficiency the type of belt drive of economic and reliable easy to use.
