Abstract
The invention provides a motor head gear train belt tightener which consists of a mandrel, a belt pulley and a bearing. The mandrel 1 is mounted inside the bearing 2 and in interference fit with an inner ring of the bearing, and the belt pulley 3 is mounted outside of the bearing 2 and in interference fit with an outer ring of the bearing 2. A bolt connecting hole and a regulating hole are arranged on the mandrel 1, and the bolt connecting hole 12 is eccentrically arranged. The motor head gear train belt tightener is low in cost, simple and compact in structure, convenient to mount and adjust belt, small in size and capable of enlarging wrap angle of the belt pulley. Purposes for reducing high cost and solving difficulties in adjustment and maintenance are realized, and the wrap angle of the motor head gear train belt pulley can be enlarged.
Description
Technical field
The present invention relates to motor car engine front end train system, particularly relate to the tension device of motor head train belt.
Background technique
Existing motor head train belt tension generally adopts the automatic tensioner tensioning or regulates that certain component belt pulley comes tightening belt in the front end train.Adopting automatic tensioner tensioning front end train belt is a kind of reasonable tensioning mode, can guarantee the tension force of belt, makes front end train reliable operation; But some train space is less; Cause automatic tensioner to arrange, simultaneously, the automatic tensioner price is higher; For the motor of little discharge capacity, cost is higher; Adopt to regulate front end train component belt pulley and come tightening belt, cost is lower, but regulates trouble of belt tension when maintain in the later stage, and simultaneously, some train front end train belt pulley cornerite hour also can't play the effect of increase belt pulley cornerite.This motor head train belt tightener, cost is lower, but it is more convenient to regulate belt, can increase front end train belt pulley cornerite again simultaneously, and also less to spatial requirement.
Summary of the invention
The purpose of this invention is to provide a kind of cost lower, simple in structure, compact, easy to assembly, regulate the convenient motor head train belt tightener that can increase the belt pulley cornerite again of belt, with reach reduce motor head train stretcher with high costs with regulate, maintenance difficulty and the effect that increases front end train belt pulley cornerite.
Technological scheme of the present invention is following:
A kind of motor head train belt tightener, it is made up of mandrel, belt pulley and bearing; Said mandrel is installed in the bearing and the inner ring interference fit of bearing, and belt pulley is installed in outside the bearing and the outer ring interference fit of bearing; Be distributed with a bolt connecting hole and an adjustment hole on the said mandrel, said bolt connecting hole is eccentric to be provided with.
Among the present invention, mandrel is the adjusting and the supporting structure of whole stretcher, and bolt passes the bolt connecting hole on the mandrel, and whole stretcher is fixed on the support, adopts bearing simultaneously, and when guaranteeing that stretcher rotates around the mandrel center, tensioner position is fixed.Simultaneously, because bolt connecting hole is eccentric the setting, can tightening belt or loosen belt through regulating the mandrel position.It is thus clear that the present invention is simple in structure, compact, adjusting, easy to assembly, can reaches and reduce the effect that motor head train stretcher is with high costs and regulate, maintain difficulty and increase front end train belt pulley cornerite.
Description of drawings
Fig. 1 is the composition schematic representation of front end train belt tightener assembly;
Fig. 2 is the structural representation of front end train belt tightener mandrel;
Fig. 3 is a front end train belt tightener regulation range schematic representation;
Fig. 4 is the front end train belt tightener schematic representation of in train, working.
Embodiment
Referring to Fig. 1; The present invention is made up of mandrel 1, bearing 2 (owing to be existing ordinary construction, a schematic illustration among the figure is known the Internal and external cycle that draws) and belt pulley 3; The inner ring of mandrel 1 and bearing 2 adopts is that the mode of interference fit connects together; The outer ring of belt pulley 3 and bearing 2 adopts the mode of interference fit to be connected, and is distributed with a bolt connecting hole and an adjustment hole on the mandrel 1, said bolt connecting hole 12 eccentric settings.Bolt connecting hole 12 is a circular hole, and said adjustment hole 11 is interior hexagonal blind hole.
When mandrel 1 passed on the mandrel bolt on the bolt connecting hole 12 urgent after, the inner ring of mandrel 1 and bearing 2 is fixing together, the outer ring of bearing 2 rotates under the drive of belt 7 with belt pulley 3, and is as shown in Figure 2.Wherein the characteristic of each assembly is: a hexagonal blind hole 11 is arranged on the mandrel 1; Bolt connecting hole 12; As shown in Figure 3; The effect of adjustment hole 11 is: inner hexagon spanner makes front end train belt tightener around the bolt rotation of passing bolt connecting hole 12 through this hexagonal blind hole, thus tensioning or lax front end train belt.The effect of bolt connecting hole 12 is to make bolt pass the hole of stretcher, and bolt passes this hole, and after stretcher was adjusted to certain position, urgent bolt was fixed on the support stretcher.
The regulation range of described front end train belt tightener is the twice of the eccentric distance of stretcher mandrel 1, i.e. 2R shown in Fig. 3.
Described front end train belt tightener working procedure of tightening belt in train is as shown in Figure 4, and crank pulley 9 drives accessory belt pulley 6 and accessory belt pulley 8 through belt 7, and belt 7 leans on the tensioning of described front end train belt tightener; When Idle wheel was positioned at limit inferior position 5, belt 7 did not have tension force, and can carry out the installation or removal of belt 7 this moment; After belt 7 assembles; Move stretcher rotation with inner hexagon spanner through adjustment hole 11 around bolt connecting hole 12 centers, thus tightening belt, after belt tightening meets certain requirements; Urgent bolt, thereby fixed tensioning device through bolt connecting hole 12.When tension force reduces after belt is because of the operation certain hour, unclamp bolt, again with inner hexagon spanner adjustment tensioner position tightening belt.When stretcher was in limes superiors position 4, just tightening belt again need be changed belt again.
