Abstract
The utility model relates to a timing stretcher including a rotating member, a bearing arranged on the inner wall of the rotating member, and a pivot in the bearing, a through hole is arranged on the pivot for fixing the timing stretcher and is eccentrically arranged relative to the central position of the pivot, the pivot is split into an upper pivot and a lower pivot that are detachably connected. Such a timing stretcher can reduce cost.
Description
Technical field
The utility model relates to a kind of timing stretcher.
Background technique
Be used for Timing Belt, the timing stretcher of flexible gearings such as timing chain, generally comprised rotating parts, be generally belt pulley, sprocket wheel, the rotating parts inwall is provided with bearing, be provided with pivot in the bearing, pivot is provided with a through hole, generally pass through hole and fix the timing stretcher through bolt, at present, the pivot that uses is for being wholely set, pivot is a cylindrical body, cylinder diameter and bearing bore diameter are complementary, and cylindrical both ends of the surface all are extended with flange, and lip diameter is greater than bearing bore diameter, therefore, need constitute and bearing through special purpose machinery processing when mounted, rotating parts fixedly connected, this machine price is very expensive, thereby has increased the price of timing stretcher.
Summary of the invention
The purpose of this utility model: in order to overcome the defective of prior art, the utility model is manually installed, thereby a kind of timing stretcher that can reduce cost is provided by the pivot split is provided with.
The technical solution of the utility model: a kind of timing stretcher, include rotating parts, be arranged on the bearing of rotating parts inwall and be arranged on the interior pivot of bearing, described pivot is provided with a through hole that is used for fixing the timing stretcher, described through hole is with respect to the eccentric setting in described pivot center position, described pivot includes the head lamp brush guard pivot and the following pivot of split, and described upper and lower pivot removably connects.Adopt technique scheme, make when mounted, do not need to install, directly install, thereby greatly reduce cost by manual just can the realization through special purpose machinery.
Further improvement of the utility model: described upper and lower pivot constitutes described removably connecting through screw.Adopt above-mentioned improvement, make that upper and lower pivotal mounting and dismounting are convenient.
Further improvement more of the present utility model: described rotating parts is a belt pulley, described timing stretcher also includes a spacing catch, described spacing catch one end is connected with described screw, the other end extend on the driving face of described belt pulley and and driving face between be provided with the gap.
Adopt above-mentioned improvement, make when transmitting, stuck phenomenon can not occur, transmit more stable at belt pulley.
