Description

Technical Field

[0001] The utility model belongs to the technical field of planetary brackets, and more specifically, particularly relates to a planetary bracket used in a planetary gear device. Background Art

[0002] Planetary gears are a transmission device consisting of two sets of gears, one inside and one outside. The inner gear has central teeth, called "star gears", and the outer gear has outer circular teeth, called "sun gears" or "planet gears". Planetary gears are usually used in mechanical systems that transmit high torque and achieve high-speed deceleration, such as automobile gearboxes, bicycle transmissions, etc. They have a compact structure and high transmission efficiency, and are widely used in various industrial and mechanical equipment.

[0003] Based on the above, the inventors have discovered the following problems: During use, the existing planetary brackets directly install and use the planetary gears, but when shaking occurs, the planetary gears may become detached, causing trouble to the user. At the same time, when used for a long time, the planetary gears and the surface of the planetary bracket will produce greater wear, which is quite inconvenient.

[0004] Therefore, in view of this, research and improvement are conducted on the existing structure and defects, and a planetary carrier for a planetary gear device is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0005] The purpose and effect of the planetary support for a planetary gear device of the utility model are achieved by the following specific technical means:

[0006] A planetary bracket for a planetary gear device comprises a bracket body, a plurality of groups of fixing rods are fixedly mounted on the surface of the bracket body, planetary gears are sleeved on the surfaces of the fixing rods, an arc-shaped frame is fixedly mounted on one end of the fixing rods, a limiting mechanism is installed inside the arc-shaped frame, and a connecting rod is fixedly mounted on one end of the bracket body.

[0007] Furthermore, the limiting mechanism includes a spring, a group of moving blocks are connected and installed on both sides of the spring, a group of connecting blocks are fixedly installed on one end of the moving block, a stop block is fixedly installed on one end of the connecting block, and a pull rod is fixedly installed on the surface of the moving block.

[0008] Furthermore, a group of through grooves are formed on the surface of the arc-shaped frame, and one end of the stopper passes through the through grooves and extends to the outside.

[0009] Furthermore, a slide groove is provided on an outer wall of one side of the arc-shaped frame, and one end of the pull rod passes through the slide groove and extends to the outside.

[0010] Furthermore, a cavity is provided inside the planetary gear, and a plurality of groups of micro holes are opened on the inner wall of the planetary gear.

[0011] Furthermore, a filling port is provided on the surface of the planetary gear.

[0012] Furthermore, the planetary gear is in contact with the surface of the fixing rod.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] Through the cooperation between the spring, the moving block, the connecting block and the stop block, when installing the planetary gear, the staff needs to first pull the pull rod to drive the moving block to move, which can drive the connecting block and the stop block to move, and then the planetary gear can be installed on the fixed rod, and the pull rod can be loosened at the same time. Under the action of the spring, the planetary gear can be effectively limited to avoid shaking that causes the planetary gear to disengage, etc. The operation steps are very simple, which indirectly improves the use efficiency of the bracket, and the design greatly increases the practicality.

[0015] Through the cooperation between the chamber and the micro-holes, the staff can add lubricating oil into the chamber through the filling port during regular maintenance. Then, under the action of the micro-holes, the planetary gears can be effectively lubricated during operation, avoiding large wear and tear due to long-term use, and indirectly increasing the service life of the bracket. It is very simple. BRIEF DESCRIPTION OF THE DRAWINGS
