FIXING AND DRIVING MECHANISM WITH SPIRAL BALL DUCT FIELD OF INVENTION
This invention relates to a fixing and driving mechanism with spiral ball duct, which is designed to replace the main shaft component in spiral lifting systems and developed to provide additional functions that cannot be provided by the existing mechanisms, as well as improve working conditions by realizing the functions provided by existing mechanisms in a different manner.
DEFINITION OF INVENTION The driving mechanism according to this invention is designed to improve the operating principle of the spiral lifting mechanism. Since there is no other machine or system operating based on this principle, there is no other similar product except for the existing mechanism. The mechanism according to this invention is designed to replace the main shaft component used in the existing mechanisms and to eliminate the unfavorable parameters determined in that component.
The unfavorable parameters observed in the existing spiral lifting mechanisms are given below: a) The cost of the cam bearing mechanism is very high.
b) Installation of the part is time-consuming and difficult.
c) The part drives the system in one direction.
d) The part cannot be manufactured below a definite size.
e) It is not suitable for mass production.
The most important difference between the product according to this invention and the existing mechanisms is that the system comprises a part specifically designed depending on the required function. Since the cam bearing, which is one
of the most important components of the existing systems, is imported from foreign countries, the general structure of the system is created based on this component. However, the existing system results in high costs, inability to design it in the required sizes, and difficulties in installation.
Advantages provided by the fixing and driving mechanism with spiral ball duct developed according to this invention are listed below:
• The system according to this invention consists of parts, which are suitable for mass production.
• A more efficient and sensitive mechanism is designed in terms of fixing and driving.
• It allows operation under load (pulling, compression load) in both directions.
• Since there are many cam bearings in a driving component with cam bearing, its cost is very high. The mechanism according to this invention eliminates the need for cam bearings, decreases the number of installation and minimizes the costs.
• Installation of the cam bearings on the main part is a time-consuming and difficult process in production. The mechanism according to this invention facilitates such processes.
• The forces applied on the helical band in the existing mechanisms are asymmetrical, so the mechanism operates in one direction. The mechanism according to this invention balances such forces and thus the mechanism can be operated in both directions.
• «The mechanism developed applies compression force at more points on the helical band compared to the existing mechanisms and this compression force is applied equally on both sides of the band. Thus, the
mechanism becomes more stabile and resistant. This feature extends the service life and operating capability of the mechanism.
• The difference in wall thicknesses between the interior and exterior surfaces of the helical band increased when the wrapping diameter of the band is decreased. This difference in wall thicknesses causes small gaps while fixing the band in the systems with a cam bearing. Such gaps affect fixing and operation of the system and may cause failures in the system in time. Therefore, if any existing mechanism is manufactured under a definite diameter, such problems will occur and this will constitute a restriction while determining the sizes of the mechanism. Since the compression force applied on the helical band in the part according to this invention is a point compression, the heights of the interior and exterior ball ducts can be adjusted. Thanks to this adjustment, the helical band can be fixed securely even if it is wrapped with smaller diameters and smaller mechanisms can be manufactured. Thus, smaller mechanisms can be manufactured, which are difficult to manufacture using the existing methods.
• This part, which is used in the existing spiral lifting systems, is the most expensive and important part of the system in terms of installation. The part according to this invention is manufactured using metal injection method. Thus, a more advantageous part is obtained in terms of both production speed and costs. The main operating principle of the system according to this invention is given below:
It can be defined as a spiral geometry by installing a cylindrical pipe on the cam bearings with a definite angle of climb. This geometry may seem asresemble to screw pitches.
The helical band installed by moving along this spiral path created by the cam bearings raises one screw pitch created in one full round. Thus, the system can operate without friction. Here, the main purpose is to drive the helical band on a surface without friction. This frictionless surface is created linearly in the system with cam bearings. The frequency of such lines that create this surface is determined according to the diameter of the cam bearing used. For example, 12 cam bearings are required to create one single round spiral pitch on the cylindrical pipe with a diameter of 40 mm. Based on this example, it may be concluded that the helical band should contact the frictionless surface at 12 linear points.
Cam bearings are required to fix the upper part of the helical band as its lower part. The number of cam bearings that will have an effect on this surface is decreased by half because the system is designed to carry the load in one direction.
In the product according to this invention, the surface geometry consists of specific parts with specifically processed surface geometry. Thus, the limitations in the existing system are eliminated by the system according to this invention and a more advanced mechanism is produced in technical terms. For example, since the surface, on which the helical band will operate, is specifically manufactured to include balls, the number of the contact points is 8 times that of the contact points in the example given above. This allows a more stabilized structure to fix and operate the band.
Since the parts used in the system according to this invention to fix and operate the helical band are produced using the metal injection method, they are considerably cheaper and can be produced domestically. Thus, dependency on foreign countries is decreased in production.
In the existing mechanism, the contact between the cam bearing and helical band is linear and cannot be changed. However, since the helical band is manufactured
by wrapping, different wall thicknesses are observed on its interior and exterior sides. This difference in wall thicknesses requires contact points at different heights on the interior and exterior sides of the helical band in order to align it accurately. The difference in the wall thicknesses of the helical band increases with the decrease in the wrapping diameter and this imposes a limitation on the size of the existing mechanism.
The mechanism according to this invention allows for production of smaller mechanisms. Thus, the heights of the interior and exterior ball ducts can be adjusted in the product according to this invention. This adjustable height allows for accurate alignment of the helical band and prevents gaps.
Since the system according to this invention operates based on the principle of coupling two bands together, the height adjustment of the ball duct is very important in order to fix the helical band and to allow robust operation of the system.
The existing mechanism was designed to operate under compression force. The load is carried by being transmitted to the bearings over the cylindrical pipe formed by coupling two bands. There, the part associated with the bearings is the helical band. Thus, in the mechanism according to this invention, the bearings are located more frequently at the side of the helical band, which bears the load. A number of bearings, which will allow for fixing the helical band, are located on the upper side. This number is half the number of bearings on the lower side.
If it is required to modify the existing system to achieve bidirectional operation, it will be required to increase the number of bearings on the upper side. But this will increase the cost of this part, which is already expensive. The mechanism according to this invention not only decreases such costs but also allows bidirectional operation. In other words, the system according to this invention can work against both compression and traction loads.
Some features that can be developed more in this invention may be listed as follows:
The spiral path that fixes the helical band may be made longer using new techniques and thereby the robustness and load-carrying capability of the system can be increased. In addition, decreasing the installation parts using different production techniques will allow a more effective system in terms of production and cost-effectiveness.
