Description
Technical Field
The invention belongs to the technical field of equipment assembly, and relates to a quick installation tool for a planet wheel roller pin of a speed reducer.
Background
In the installation process of the planetary gear reducer, because the inner holes of the planetary gears are very small, a plurality of needle roller mandrels are required to be installed in the inner holes of the three planetary gears to replace a common bearing, so that the mechanical load friction coefficient of equipment in the transmission process is reduced. However, the needle rollers installed in the planet wheels are manually plugged in sequence, so that the needle rollers can fall off by two in the process, the installation mode is difficult to guarantee the assembly time of personnel, and the assembly efficiency of products is difficult to improve.
Disclosure of Invention
The invention aims to provide a quick installation tool for a planet wheel roller pin of a speed reducer, which can solve the problem of low installation efficiency of the roller pin.
According to the technical scheme provided by the invention: the quick installation tool for the planet wheel roller pins of the speed reducer comprises a base, wherein a planet gear positioning groove is formed in the middle of the base, a guide rod is installed in the planet gear positioning groove, the roller pin positioning groove is formed in the periphery of the guide rod, and a stop ring is arranged in the periphery of the guide rod.
As a further improvement of the invention, a guide rod fixing threaded hole is processed in the middle of the planetary gear positioning groove, a connecting screw rod is arranged at the bottom of the inverted rod, and the connecting screw rod is positioned in the guide rod fixing threaded hole.
As a further improvement of the invention, the needle roller positioning groove is in an open arc shape.
As a further improvement of the invention, the inner circumference of the retaining ring is greater than 0.00.0mm of the outer circumference of the guide rod.
As a further improvement of the invention, the guide rod is made of steel materials and is subjected to quenching treatment.
Compared with the prior art, the invention has the following advantages:
1. the invention has the advantages of low manufacturing cost, simple structure and low requirements on personnel and working environment, and can be operated at any time and any place.
2. The device can realize quick installation for installing the planet wheel roller pin, is convenient to replace and low in maintenance cost, and can greatly improve the production efficiency.
Drawings

Fig. 2 is a top view of fig. 1.
Fig. 3 is a schematic structural diagram of the base of the present invention.
Detailed Description
The following further describes embodiments of the present invention with reference to the drawings.
In the figures 1-3, the device comprises a guide rod 1, a roller pin positioning groove 1-1, a check ring 2, a roller pin 3, a planet wheel 4, a base 5, a planet gear positioning groove 5-1, a guide rod fixing threaded hole 5-2 and the like.
As shown in figure 1, the invention discloses a quick installation tool for planet wheel roller pins of a speed reducer, which comprises a base 5, wherein as shown in figure 3, the middle of the base 5 is provided with a planet gear positioning groove 5-1, the shape of the planet gear positioning groove 5-1 is matched with that of a planet wheel 4, and the middle of the planet gear positioning groove 5-1 is provided with a guide rod fixing threaded hole 5-2. A guide rod 1 is installed in a base 5, a connecting screw rod is arranged at the bottom of a reversing rod 1 and is positioned in a guide rod fixing threaded hole 5-2, as shown in figure 2, a roller pin positioning groove 1-1 is formed in the outer periphery of the guide rod 1, the roller pin positioning groove 1-1 is in an open arc shape, a roller pin 3 can be enabled to be tightly attached to the inner periphery of a planet wheel 4, a check ring 2 is arranged on the outer periphery of the guide rod 1, and the size of the inner periphery of the check ring 2 is slightly larger than.
The working process of the invention is as follows:
when the roller pins are installed, a connecting screw rod at the bottom of the guide rod 1 is screwed into the guide rod fixing threaded hole 5-2, the guide rod 1 is in contact with the base 5 for fixation, then a small amount of lubricating grease is coated on the inner periphery of the planet wheel 4, then the roller pins are sleeved into the planet gear positioning grooves 5-1, then the roller pins 3 are placed into the roller pin positioning grooves 1-1, the anti-return rings 2 are sleeved on the guide rod 1, then the guide rod 1 is pulled out, the anti-return rings 2 block the upper ends of the roller pins 3, and the roller pins 3 are prevented from sliding out of the. And finally, taking down the retaining ring 2, and finishing the installation of the planet wheel roller pins.
