Abstract
The utility model provides a gear transmission part group of a garage door lifting motor. The gear transmission part group comprises a gear ring body connected to a worm in the garage door lifting motor, a transmission shaft connected to a speed reducer of the garage door lifting motor, and a plastic connection body connected to the gear ring body and the transmission shaft, wherein six grooves are uniformly distributed in an inner ring of the gear ring body; the plastic connection body is provided with bulges matched with the grooves; and the gear ring body and the plastic connection body are coaxially connected to the transmission shaft. The gear transmission part group of the garage door lifting motor provided has the beneficial effects that as the structure that the gear ring body is connected with the plastic connection body is adopted, and the gear ring body, the plastic connection body and the transmission shaft are connected to form a whole body by an injection molding process, the manufacturing cost can be effectively reduced, the strength of the tooth part of the gear ring body and the self-locking capability of the lifting motor are improved, noises of the motor are obviously reduced, the comfortableness of a user is ensured in the operation of the motor, and meanwhile, the service life of the motor is prolonged.
Description
Technical field
The utility model relates to a kind of garage door lifting motor, especially relates to a kind of gear driving member group of garage door lifting motor.
Background technique
The gear driving member group (as shown in Figure 1) of existing garage door lifting motor mainly comprises gear ring body, plastic connecting body, transmission shaft composition.Plastic connecting body is connected with the gear ring body in this structure, exists the not high easy damage of tooth portion intensity of gear ring body, the defective of self-locking performance difference.Its main cause is to cause with plastic connecting body and used material and the linkage structure of gear ring body; Mainly show: 1. the tooth portion material of gear mass is plastics; Its intensity is on the low side, and self-locking performance is poor, causes the garage door lifting motor wheel tooth in use to occur and damages; Lose function of use, glide automatically because of self-locking performance missionary society causes overhead door simultaneously; 2. the tooth portion material of gear mass is a cast iron, though this structure tooth portion's intensity and self-locking performance increase, noise increases during with the worm screw routing motion, directly influences user's travelling comfort, the working life of also having reduced motor; 3. the tooth portion material of gear mass is a tin Qiang copper, though this structure tooth portion's intensity and self-locking performance and noise can both be able to satisfy customer requirements, too high cost all can't be accepted manufacturer and user.
The model utility content
The purpose of the utility model provides the gear driving member group of the garage door lifting motor that a kind of motor gear ring body tooth portion intensity is high, self-locking performance is good, noise of motor is little, cost is low.
The utility model solves the technological scheme that its technical problem adopted: a kind of gear driving member group of garage door lifting motor; Comprise the gear ring body that connects turbine in the garage door lifting motor, the transmission shaft of connection garage door lifting motor retarder and the plastic connecting body that connects gear ring body and transmission shaft; It is characterized in that: be provided with six grooves that are uniformly distributed with in the inner ring of described gear ring body; Described plastic connecting body is provided with the convexity that matches with groove, and described gear ring body, plastic connecting body is coaxial is connected on the transmission shaft.
Concrete, on the surface of described transmission shaft one end annular knurl is set circumferentially.
The beneficial effect of the utility model: owing to adopt gear ring body and plastic connecting body linkage structure; And adopt Shooting Technique that gear ring body, plastic connecting body, transmission shaft three are combined as a whole; Can effectively reduce manufacture cost, improve the tooth portion intensity of gear ring body and the self-locking performance of lifting motor, the noise of motor obviously reduces; User's comfortable feel when guaranteeing the motor operation, the working life of improving motor simultaneously.
Below will combine accompanying drawing and embodiment, the utility model will be carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is the structure sectional view of the gear driving member group of garage door lifting motor of the prior art.
Fig. 2 is the structure sectional view of the utility model.
Fig. 3 is the structure exploded perspective view of the utility model.
Among the figure: 1. gear ring body, 2. plastic connecting body, 3. transmission shaft, 4. groove, 5. convexity, 6. annular knurl.
Embodiment
Embodiment; As shown in Figure 1; A kind of gear driving member group of garage door lifting motor comprises the gear ring body 1 that connects turbine in the garage door lifting motor, the transmission shaft 3 of connection garage door lifting motor retarder and the plastic connecting body 2 that connects gear ring body 1 and transmission shaft 3.
Like Fig. 2, shown in Figure 3; Described copper gear ring body 1 its material is a tin Qiang copper; Be provided with six grooves that are uniformly distributed with 4 in the inner ring of copper gear ring body 1, described plastic connecting body 2 is provided with the convexity 5 that matches with groove 4, described gear ring body 1, plastic connecting body 2 coaxial being connected on the transmission shaft 3.Described transmission shaft 3 materials are selected round steel for use No. 45, and surface hardening is handled, and hardness requirement is HRC35-40.On the surface of described transmission shaft 3 one ends annular knurl 6 is set circumferentially.
Described gear ring body 1, plastic connecting body 2, transmission shaft 3 are connected to an integral body through Shooting Technique.
Above embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that the common engineers and technicians in related domain make the technological scheme of the utility model all should fall in the protection domain that claims of the utility model confirm.
The utility model does not relate to all identical with the existing technology existing technology that maybe can adopt of part to be realized.
