Embodiment Construction

[0037] According to reference Figure 6-11B In the described invention, the new and improved chain tensioner bottom bracket B includes mounting tabs and retention features to confine the spring group of one or more springs in the bottom bracket, while still allowing the springs ( One or more) are installed in the bottom bracket. Image 6 with 7 Each is a front (outside) and rear (inside) view of the tensioner blade assembly BAS, which includes a bottom bracket B formed according to the present invention, and includes first and second leaf springs S (1S, 2S) operably installed . As stated above, a single spring S may be used for the tensioner blade assembly BAS instead of two or more springs 1S, 2S without departing from the scope and intent of the present invention, but the description herein with reference to exemplary embodiments includes a set of two Tensioner blade assembly with 1S and 2S springs. Compared with the above-mentioned base B', similar components and features o...

Abstract

A chain tensioner includes a shoe including a first spring-receiving slot and a second spring-receiving slot. The first slot includes a first side wall and a first installation tab. The second slot includes a second side wall and a second installation tab. A stack of one or more leaf springs is installed into the first and second spring-receiving slots over first and second installation tabs, and a first end of the stack is laterally retained in the first slot between the first installation tab and first side wall, and a second end of the stack is laterally retained in the second slot between the second installation tab and second side wall. The installation tabs are necessarily lower in height than first and second side walls to allow the spring stack to be installed thereover. The first and second installation tabs are each located in an outboard position and the first and second side walls are located in an inboard position. The outboard position enables the installation tabs to capture the spring stack despite the lower height.

Description

[0001] Cross references to related applications [0002] This application claims the priority of U.S. Provisional Patent Application Serial No. 61 / 735,028 filed on December 9, 2012 and the benefits of its filing date, and the entire disclosure of the provisional application is expressly incorporated into the specification of this application by reference. Background technique [0003] The present invention generally relates to an automobile chain drive system, and more specifically, to a mechanical blade type chain tensioner device that limits the space for applying tension to a chain moving through. Existing blade-type chain tensioning equipment includes chain engaging blades or bottom support elements, usually molded from a resin plastic material, which has a metal spring installed therein to provide the necessary rigidity and damping characteristics while using the plastic bottom support Flexible, low-friction, and good wear-resistant bottom bracket components.
